Q:What exactly is surgical stainless steel made of (metals)? Does it contain nickel? If so, what % does it usually contain? I am deciding between surgical stainless steel piercings or titanium. Both same price and looks. I want to know which one is more hypo-allergenic and generally nickel free.

surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel. and some proportion of molybdenum. The word 'surgical' refers to the fact that these types of steel are well-suited for making surgical instruments: they are easy to clean and sterilize, strong, and corrosion-resistant. The nickel/chrome/molybdenum alloys are also used for orthopaedic implants as aids in bone repair, and as a structural part of artificial heart valves and other implants. However, immune system reaction to nickel is a potential complication. In some cases today titanium is used instead in procedures that require a metal implant which will be permanent. Titanium is a reactive metal, the surface of which quickly oxidizes on exposure to air, creating a microstructured stable oxide surface. This provides a surface into which bone can grow and adhere in orthopaedic implants but which is incorrodible after implant. Thus steel may be used for temporary implants and the more expensive titanium for permanent ones

Q:Can steel coils be coated with tin?

Yes, steel coils can be coated with tin through a process called tinplating. Tinplating provides corrosion resistance and enhances the appearance of the steel surface.

Q:What are the guidelines for handling damaged steel coils?

The guidelines for handling damaged steel coils typically involve assessing the extent of the damage, ensuring proper safety precautions are in place, and following industry best practices for handling and storing damaged coils. It is important to inspect the damaged coils for any potential hazards, such as sharp edges or protruding objects, and to use appropriate lifting equipment and protective gear when moving or transporting them. Additionally, damaged coils should be segregated from undamaged ones to prevent further deterioration and potential safety risks.

Q:I'm doing a commercial for chemistry and I need to know any kind of chemistry dealing with Callaway Big Bertha Irons. I know they are stainless steel but any more info would help out! Thank you! :)

Stainless steel is a mixture of metals, each metal is included in order to make up for each others weaknesses. Each metal is included due to a property that is benificial in some way, for instance Chromium is included because it makes the stainless steel 'stainless'. In chemistry a mixture of metals, stainless steel, is called an alloy.

Q:What are the common methods of recoiling steel coils?

Manufacturers and customers have various options when it comes to recoiling steel coils. One frequently used method is slitting, which employs rotating circular blades to cut a wide steel coil into narrower strips. This results in multiple smaller coils with desired widths. Slitting is commonly employed to create coils of different sizes for diverse applications. Another technique is known as cut-to-length (CTL) recoiling, where the steel coil is cut into specific lengths according to the customer's requirements. This involves passing the coil through a straightening and leveling machine, followed by a flying shear that cuts the steel into the desired lengths. CTL recoiling is particularly useful in industries that demand precise and uniform steel lengths, such as construction or automotive. Furthermore, there is a method called coil-to-coil recoiling. This process involves rewinding the steel coil onto a new coil with the desired dimensions and properties. Coil-to-coil recoiling is typically utilized when the original coil needs resizing, reconditioning, or rerolling for further processing or transportation purposes. Specialized recoiling machines ensure proper tension, alignment, and winding of the steel coil onto the new coil. In conclusion, the recoiling of steel coils can be accomplished through various methods, including slitting, cut-to-length recoiling, and coil-to-coil recoiling. Each method offers its own advantages and is chosen based on factors such as required coil dimensions, precision, efficiency, and the specific needs of the industry or customer.

Q:How are steel coils inspected for quality control?

Steel coils are inspected for quality control through a series of rigorous tests and inspections. This typically involves visual checks for any surface defects, such as scratches or dents, as well as measurements of dimensions, weight, and thickness. Additionally, non-destructive testing techniques like ultrasonic or magnetic particle testing may be conducted to detect internal flaws or inconsistencies in the steel. These comprehensive inspections ensure that only high-quality steel coils are approved for use.

Q:Or is it a coating that is applied? If so what types of steel? Or what types of coatings?

there is a weathering steel that corrodes and then stops. The outer surface of the steel is a rusty looking brown but after the first layer of rust appears, the process stops. It used to be called A588 steel. So called mild steel is not A36 anymore, it is A992 (50 ksi yield). The only material that is A36 anymore are angles, channels, and plate. You can coat the steel with an epoxy coating to protect the steel from this highly corrosive environment. Google a company called TNEMEC. They offer epoxy coatings for steel and other coatings. Weathering steel and epoxy coating are not cheap options.

Q:What are the different methods of edge wave correction for steel coils?

There are several methods of edge wave correction for steel coils. One common method is using edge trimmers, which cut off the uneven edges of the coil to create a straighter edge. Another method is through tension leveling, where the coil is stretched to remove the wave-like deformities. Additionally, some manufacturers use roller leveling, where the coil passes through a series of rollers that press and flatten the edges. Lastly, laser technology can be employed to accurately measure and correct any edge wave deformities.

Q:How are steel coils used in the production of household goods?

Steel coils are used in the production of household goods as they are a primary material for manufacturing various products. They are commonly used in appliances, such as refrigerators, stoves, and washing machines, as well as in furniture, shelving units, and even construction materials. The steel coils are typically shaped, cut, and formed into specific components or structures required for these household goods, ensuring durability and strength in the final products.

Q:What are the dimensions of steel coils used in the construction equipment industry?

The dimensions of steel coils used in the construction equipment industry can vary, but they are typically around 48 to 72 inches in width and have an outer diameter of 60 to 80 inches. The weight of these coils can range from 5,000 to 30,000 pounds.
