Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

 

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

 

Q6: What is the difference between galvanized steel and Galvalume steel?

A6: Galvanized steel is metallic coated with Zinc in various coating weights. Minimum recommended for painted metal roofs is G90. Galvalume is a zinc and aluminum coated steel that becomes an alloy and is recommended in either painted or bare applications with a minimum coating weight of AZ50. Galvalume has an excellent performance life in bare exposures. Hence if you are using a bare panel use Galvalume and if painted use either.

Q:I have never owned a non-stainless steel chef's knife and have been looking at some to buy recently, but all of them have various degrees of wear and use. They say that the wear is normal for non-stainless steel knives, but how can I tell if it is too much wear, or if the blade is clean?
cold rolled steel waers as you carve meat. If the blad if to thin you may want a better one. Utica knife in utica N.Y. made them up to about 10 years ago and i still buy them at auctions.
Q:I have a white gold engagement ring, and to be special I thought I'd get a plain band from Tiffany's--in stainless steel. Can stainless steel be worn with white gold or will there be a difference in the color or texture? I'm not planning on getting them soldered together, but I don't want it to be noticeable that they are different metals. Does anyone have experience in this subject?

Q:What are the common storage defects in steel coils?
Steel coils can suffer from various storage defects, including staining or discoloration, rust or corrosion, coil deformation, surface damage, edge damage, coil slippage, contamination, and coil nesting. These defects can negatively impact the appearance, quality, usability, and safety of the steel. To prevent these defects, it is essential to implement proper handling, storage, and protection measures. This involves storing the steel coils in a dry and well-ventilated area, away from moisture and chemicals. Additionally, appropriate stacking and support structures should be used to prevent deformation and bending. To avoid mishandling and transport damage, it is important to stack and handle the coils correctly. Adequate protection against impacts and contaminants should be provided to prevent surface scratches, dents, and abrasions, as well as edge damage. It is crucial to ensure that the edges of the coils are properly protected and secured during storage to maintain their usability and safety. Furthermore, to prevent coil slippage and potential harm to personnel or equipment, the steel coils should be securely stored and stacked. To avoid contamination, the coils should be kept away from substances like dirt, oil, grease, and chemicals. Regular inspections and maintenance should be conducted to identify and address any potential defects or issues promptly. Overall, by implementing these proper handling, storage, and protection measures, the occurrence of these common storage defects in steel coils can be minimized, ensuring the appearance, quality, usability, and safety of the steel.
Q:What are the common thicknesses available for steel coils?
The specific requirements and applications determine the available common thicknesses for steel coils. However, various industries commonly produce and use certain standard thicknesses. Typically, steel coils can range in thickness from 0.005 inches to 0.5 inches or more, depending on the type of steel and its intended use. For instance, in automotive manufacturing, where steel coils are utilized for body panels and structural components, the thicknesses commonly range from 0.5 mm (0.020 inches) to 3 mm (0.118 inches). In the construction industry, steel coils are employed for roofing, siding, and structural framing. The common thicknesses can vary from 0.014 inches to 0.062 inches, depending on the specific application and structural requirements. Similarly, appliances manufacturing, such as refrigerators, washing machines, or HVAC systems, frequently employ steel coils with thicknesses ranging from 0.018 inches to 0.035 inches. It is important to note that these are only a few examples of common thicknesses, and variations can occur based on the specific requirements of different industries and applications. Custom thicknesses can also be produced upon request to meet unique needs in various sectors.
Q:How are steel coils used in the manufacturing of industrial valves?
Steel coils are used in the manufacturing of industrial valves as they provide the necessary raw material for creating valve bodies, stems, and other components. The coils are shaped, cut, and formed into different valve parts, ensuring strength and durability. These steel components are then assembled, welded, and machined to create fully functional industrial valves used in various applications such as oil and gas, chemical processing, and water treatment industries.
Q:I noticed that Jimmy Page finger picked on a steel acoustic guitar on quite a few tracks like Stairway to heaven and other ones and I was wondering how did he do it? I know it is more difficult to finger pick on a steel acoustic because of the rougher steel strings and higher tensions so I was wondering do they make specific strings that allow for fingerstyle playing? Also Randy Rhoads finger picked a steel acoustic on Dee along with a Classical guitar.

Q:How are steel coils inspected for camber using laser profiling?
Steel coils are inspected for camber using laser profiling, which is a non-contact measurement technique. Laser profiling involves the use of a laser beam that is emitted onto the surface of the steel coil. As the laser beam moves across the coil, it creates a profile of the coil's surface, capturing precise measurements. To inspect for camber, the laser profiling system scans the entire length and width of the coil, capturing data points at regular intervals. These data points are then analyzed to determine the deviation from a straight line, which indicates the presence of camber. During the inspection process, the laser profiling system compares the measured profile of the steel coil to a reference profile, which represents an ideal or straight surface. The deviation between the measured profile and the reference profile is calculated, and if this deviation exceeds a predetermined threshold, the coil is flagged as having camber. Laser profiling offers several advantages for inspecting steel coils for camber. Firstly, it provides a non-contact measurement, eliminating the need for physical contact with the coil and reducing the risk of damage. Additionally, laser profiling is highly accurate, capable of capturing even small deviations in the coil's surface. This ensures that camber is detected reliably, allowing for necessary corrective actions to be taken. Overall, the use of laser profiling for inspecting steel coils for camber ensures efficient and accurate detection of this defect, enabling manufacturers to maintain high-quality standards and deliver reliable products to customers.
Q:I know that carbon steels and alloy steels are different but are carbon steels still alloys?Thanks!
Yes. it's an alloy of iron and carbon. Carbon steel can either mean plain carbon steel which is steel that doesn't have significant amounts of other elements, like chromium, manganese, or molybdenum. It can also be used to refer to ANY steel that is NOT a stainless steel. Alloy steel is any steel that has greater than 1% of other elements added to it besides carbon. Stainless steel might be in a certain sense be considered alloy steel but I think most people in the steel business consider it as it's own separate material from carbon steels. Many stainless steels contain only trace amounts of carbon, so they should rightly be considered iron-chromium alloys, not steel, which by default refers to iron-carbon alloys. Note that nearly all modern carbon steels also contain 0.2%-0.5% manganese and silicon. Even steels that are otherwise considered plain carbon and not alloy steels. Mn and Si are added because they prevent defects in cast steel ingots, and hot rolled items like billets and plates. However at low levels they don't affect the properties of the steel greatly.
Q:What are the different types of steel coatings for coil protection?
Some of the different types of steel coatings for coil protection include galvanized coatings, metallic coatings, organic coatings, and polymer coatings.
Q:How are steel coils inspected for uniformity?
To ensure uniformity, steel coils undergo a series of visual and mechanical tests. First, the coil's external appearance is carefully examined for any visible defects like dents, scratches, or rust. This is crucial to maintain the coil's integrity and prevent potential issues during further processing. Next, non-destructive testing techniques such as ultrasonic or magnetic particle inspection are used to measure the coil's thickness at various points. This helps identify any variations in thickness that could affect the overall quality and performance of the coil. Precise instruments are also employed to measure the coil's width and ensure it adheres to the required specifications. This is important for compatibility with downstream processes and applications. Furthermore, the weight of the coil is measured to verify if it falls within the specified range. Weighing scales or load cells are typically used for this purpose, ensuring consistent weight that meets the required standards. For internal inspection, steel coils may undergo eddy current testing, a non-destructive method that detects surface and near-surface defects. By utilizing electromagnetic induction, this technique can identify irregularities in the metal, such as cracks, voids, or inclusions. In summary, a comprehensive combination of visual inspections, thickness measurements, width checks, weight verification, and internal testing methods ensures thorough inspection for uniformity in steel coils. These rigorous processes guarantee the quality and reliability of the coils, enabling them to meet industry standards and customer requirements.
