Galvanized steel coil

Introduction:

The galvanized steel coil is made by cold rolled steel sheet, then trough chromated. unoiled, various spangles, hot dipped. The surface is coated by zinc or aluzinc. it is widely used as the raw materials of building. we have exported to midle east, africa, south america, ukraine for the good quality and best credit.

Q: I noticed a friend's appliances are not magnetic, and mine are. Both are stainless steel. Are there two types of stainless steel or something? Thanks: There are many types of stainless steel. Some are magnetic and some are non-magnetic. The magnetic properties of stainless steel are very dependent on the elements added into the alloy, and specifically the addition of nickel can change the structure from magnetic to non-magnetic. Poor heat treatment or high heat input welding of normal or high carbon austenitic stainless steels will cause sensitization, ie formation of chromium carbides. The formation of carbides not only reduces the corrosion resistance of the stainless steel but also tends to form martensite around the carbide. This martensite is magnetic and the more severe the sensitisation, the stronger are the magnetic properties. When nickel is added, for instance, the austenite structure of iron is stabilized. This crystal structure makes such steels non-magnetic and less brittle at low temperatures. Martensitic stainless steels are magnetic. *Wrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, ie they are not attracted significantly by a magnet. However, if they are cold worked they will be attracted to a permanent magnet. The change occurs because the cold work deformation induces a transformation of the microstructure from austenite to martensite. The effect is less marked in alloys with high concentrations of austenite stabilisers such as nickel, nitrogen and carbon. Once the martensite is formed, it may also become magnetised. *In contrast to the austenitic alloys, ferritic stainless steels such as 409 or 3Cr12/5Cr12 and martensitic stainless steels such as 420, are strongly attracted to a magnet even in the annealed state. The duplex and super-duplex stainless steels will also be strongly attracted because they contain about 50% ferrite in their microstructure. *

Q: A friends of mine says he has balls of steel and i told him i would melt em off with lava. He said it wouldnt work. i disagree: united is right! its hard to tell the temp... Because lava is not just obsidian, or pillow lava... its several different types of elements. It just depend on ground chemistry.

Q: How are steel coils used in the energy sector?: Steel coils are used in the energy sector primarily for the manufacturing of electrical transformers and power generation equipment. The high strength and durability of steel make it an ideal material for constructing these critical components, ensuring efficient energy transmission and distribution.

Q: How are steel coils inspected for damage during transportation?: Steel coils are typically inspected for damage during transportation through visual inspections and non-destructive testing methods such as ultrasonic testing, magnetic particle inspection, and eddy current testing. These inspections help identify any cracks, dents, or other forms of damage that may have occurred during transportation.

Q: How are steel coils used in the production of steel connectors?: Steel coils are used in the production of steel connectors by being fed into a machine where they are unwound and straightened. The straightened steel is then cut into appropriate lengths and shaped into the desired connector form. This process helps ensure consistency, strength, and efficiency in manufacturing steel connectors.

Q: We bought a new fridge and the magnets don't stick to the front where the stainless steel is.: The stainless steel which dont exhibit magnetic properties are austenitic grades of steel.

Q: How are steel coils tested for strength and durability?: Steel coils are typically tested for strength and durability through a series of rigorous procedures such as tension and compression tests, hardness tests, and impact tests. These tests help determine the coil's ability to withstand various loads and impacts, ensuring that it meets the required strength and durability standards. Additionally, other tests like fatigue tests and corrosion resistance tests may also be conducted to further assess the coil's performance and longevity.

Q: i mean the properties include the elasticity, impact load and ductility. am doing assignment about the perfect material that should be possessed by spring and i found alloy steel is the perfect and am confused whether stainless steel is the same with alloy steel ?: Alloy steel is a stainless steel. The differences between the two are the composition of the metal. Alloy steel is steel with usually less than 5% of other elements, like molybdenum, copper, chrome while stainless steel is a steel with at least 10-11% of chromium.

Q: is there a type of steel that is stronger or does the rail represent the top of the line?: No, train tracks are not made of the strongest steel. Actually, I believe they are made from a rather mild steel, maybe a high-carbon steel in the curves, but no means is this top of the line. Probably the best all around high strength steel, if you count hardness, tensile strength, shear, and yield is Eglin steel. It has a yield of about 245,000 psi an ultimate strength of around 293,000 psi a harness of 45.6 and an impact of about 75 joules. It's cheaper than exotic alloys, you can build aircraft with the stuff because weight isn't an issue and it's plenty strong enough. Its also very strong even in extreme temperatures. The material has a wide range of other applications, from missile parts and tank bodies to machine parts.

Q: density of mild steel (MS) is 7850 KG per metre cube , but i want to know the density of stainless steel: Stainless steels are the most dense, coming in at 8000 kg/m3. Though the densities vary, The answer is 8000 kg/m3. 301 stainless density values seem to vary according to the supplier data sheets, from 7.88 g/cc, (AK Steel) to 8.03 g/cc, (Allegheny Ludlum)
