321 stainless steel is an austenitic stainless steel of excellent corrosion resistance at room temperature, as well as good high-temperature strength and creep resistance.

201 stainless steel is the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.

A36 is a carbon structural steel coil whose chemical composition and mechanical properties strictly conform to American ASTM standards. Good mechanical properties, welding performance and corrosion resistance are basically why they are widely used in construction, bridges, machinery manufacturing and other fields.

ASTM A283 cold rolled steel coil has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.

ASTM A514 steel is available in several grades. And they have the same mechanical properties. ASTM A514 steel coils are conventionally quenched and tempered steel with high yield strength, weldability and toughness. ASTM A514 steel is a special high-strength steel, mainly used as building structural steel.

A572 steel has four different grades: 42, 50, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.

SPCC steel is produced by subjecting hot rolled steel to a cold rolling process, which not only improves its surface finish but also enhances its mechanical properties.

A573/A573M steel has grades including 58, 65 and 70. The coil is suitable for structural grade carbon-manganese-silicon steel in 3 tensile strength ranges. ASTM A573/A573M steel coils are mainly used to improve notch toughness at room temperature.

A633 steel has four grades of A, C, D, and E. The thickness of grade C can reach 4 inches and the thickness of grade E can reach 6 inches. ASTM A633 steel specification is based on the standard specification for standardized high-strength low-alloy structural steel coil, which requires high notch toughness under low temperature conditions.

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.
