Q:What is the minimum order quantity for steel coils?

The minimum order quantity for steel coils can vary depending on the supplier and specific product requirements. It is best to consult with the supplier or manufacturer directly to determine their minimum order quantity.

Q:Aluminum and Steel brittle or ductile based on these results? and why? Steel Aluminium% Elongation 0.2510.2705Modulus of E in ksi11833.33964.71Tensile Strength (ksi)87.5 51.5Yield Strength (ksi)78.5 41

Only steel(of this pair)might be liable to brittle fracture,which would be implied by almost zero elongation or reduction in area at fracture.On this basis the steel has not failed by brittle fracture.I would expect much more elongation in pure aluminium than your sample shows so I presume it to be brittle unless it is an alloy rather than commercially pure aluminium.However brittle fracture in metals is a particular phenomenon to be determined by impact tests and examination of fracture surfaces and is particularly relevant to metals with the body centred crystal structure.

Q:Help please.What atoms are there in steel?Like water is equals to 1 Oxygen atom + 2 Hydrogen atoms.Thnx 4 d help.

Steel is an alloy consisting mostly of iron, with a carbon content between 0.2 and 1.7 or 2.04% by weight (C:1000–10,8.67Fe), depending on grade. Steel is Fe(iron) and Carbon alloy. These are the atoms in certain ratio that make up steel. Its not a molecule but alloy.

Q:What is the typical lead time for ordering steel coils?

The typical lead time for ordering steel coils can vary depending on factors such as the supplier, quantity required, and current market conditions. However, it is common for lead times to range from a few weeks to several months.

Q:How do steel coils contribute to energy performance in buildings?

Steel coils contribute to energy performance in buildings primarily through their use in HVAC systems. Steel coils are commonly used in heating, ventilation, and air conditioning (HVAC) systems as heat exchangers or condenser coils. These coils help in transferring heat between the indoor and outdoor environments, allowing for effective heating or cooling of the building. The high thermal conductivity of steel enables efficient heat transfer, optimizing energy usage and enhancing the overall energy performance of the building. By facilitating appropriate temperature control and reducing energy consumption, steel coils play a vital role in improving the energy efficiency of buildings.

Q:420 440 1045 or 1065 ive bought knifes with these steel grades and i want to know which one is better.

SAE 440 is the best. Classified as high grade cutlery steel. There are various grades of 440: A, B, C, and F. 440 A is the most stain resistant while 440 C has the most carbon and can achieve the highest hardness (Best edge Retention). SAE 440 Chemistry: 16 - 18% Chromium, 0.60 - 1.2% Carbon, 0.75% Molybdenum. SAE 420 is pretty good. Classified as cutlery steel, it is a stain resistant grade but has less chromium and significantly less carbon than SAE 440. SAE 420 Chemistry: 12 - 14% Chromium, 0.15% Carbon (min), 0 Molybdenum Chromium is what makes the steel corrosion resistant. It also adds toughness. Molybdenum adds extra corrosion resistance and adds hardenability. So you can see by chemical components that 440 is highest quality although that also means more cost. 1045 and 1065 are low quality steels and you should probably never use them for a knife. The 1 indicates plain carbon steel with little other alloying elements. The last two digits indicate how much carbon is in the steel. 1045 has 0.45% carbon, mid-range hardenability. 1065 has 0.65% carbon, high hardenability. So if I had to choose I would choose 1065 over 1045 but the difference isn't that noticeable. Everything I said here assumes they have all had the optimum Quench and Temper heat-treatment for their chemistry grade.

Q:How do steel coils contribute to energy savings in buildings?

Steel coils contribute to energy savings in buildings by being used in various applications that help improve insulation and reduce heat transfer. They are commonly used in HVAC systems, where they act as heat exchangers, transferring heat between air streams. Steel coils with high thermal conductivity ensure efficient heat transfer, allowing for effective cooling or heating of air without excessive energy consumption. Additionally, steel coils are utilized in the construction of insulated walls and roofs, forming an integral part of the building envelope. This helps minimize thermal bridging, preventing heat loss or gain through the building's structure. By improving insulation and reducing energy transfer, steel coils play a crucial role in enhancing the overall energy efficiency of buildings, leading to significant energy savings.

Q:I want to know where cold formed steel framing is used, is every steel frame we see in a construction sites like houses, building and bridges cold formed steel frames? or hot formed steel framing?I also read that cold formed steel framing is used for floors, is the steel frame beneath the floor's concrete cover?Thank u very much!!

Abeer: I'm a civil/structural engineer. Cold-formed (or rolled) steel framing is typically limited to facades, studs in lightly-loaded bearing walls and non-load bearing wall studs. Hot-rolled steel members are typically used to frame steel buildings and bridges. See the article below on cold-formed steel framing.

Q:What are the different methods of coil slitting for steel coils?

There are several different methods of coil slitting for steel coils, each of which serves a specific purpose and is used in different industries. Here are some of the common methods: 1. Rotary shear slitting: This is the most widely used method for coil slitting. It involves using a set of rotating knives to cut the steel coil into smaller strips. The rotary shear slitting method is known for its high speed and accuracy, making it ideal for large-scale production. 2. Loop slitting: In this method, the steel coil is fed through a loop control system that maintains a constant tension. The coil is then cut into strips using a rotating knife. Loop slitting is commonly used for thinner gauge materials and is known for its ability to produce clean, burr-free edges. 3. Oscillating shear slitting: This method involves using a set of oscillating knives to cut the steel coil. The knives move back and forth in a rapid motion, creating a shearing effect that cuts through the coil. Oscillating shear slitting is often used for thicker gauge materials and can handle higher tensile strengths. 4. Crush cut slitting: Crush cut slitting is a method where the steel coil is cut by pressing a circular blade against the coil. The blade crushes the material, creating a cut. This method is commonly used for softer materials or when edge quality is not critical. 5. Slit edge rolling: Slit edge rolling is a method that involves rolling the edges of the steel coil after it has been slit. This process smooths out the edges and improves the overall appearance of the strips. Slit edge rolling is often used for applications that require a high-quality finish. 6. Laser slitting: Laser slitting is a newer method that uses a laser beam to cut through the steel coil. This method is precise and can handle a wide range of thicknesses. Laser slitting is commonly used for high-precision applications where edge quality is critical. These are just a few of the different methods of coil slitting for steel coils. The choice of method depends on factors such as the thickness and tensile strength of the material, the required edge quality, and the intended application of the slitted strips.
