A656 steel coil is made of a high-strength low-alloy steel commonly used in structural applications where light weight and good formability are essential. A656 steel coils are manufactured in grades of 50, 60, 70 and 80 to meet the specified yield point.

A709 steel coil is high-strength alloy steel coil that is widely used in construction, bridges, ships, automobiles and other fields. The chemical composition of A709 steel coil mainly includes carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and other elements. The carbon content is relatively high, generally between 0.22%-0.29%.

The equivalent material of GB/T700 Q275 carbon steel and low alloy steel coil is S275JR steel coil. S275JR steel coil is a general-purpose carbon structural steel. It is also a carbon structural steel and low alloy structural steel used in engineering steel and structural steel, which is usually not heat treated.

A285 pressure vessel steel coil is made of a common carbon steel used for fusion welding of pressure vessel equipment such as boilers, storage tanks, heat exchangers, etc..

A516 vessel steel coil is made of a high-quality boiler and pressure vessel steel that is very suitable for low to medium temperature applications.
