304 stainless steel is a superior material with regard to corrosion resistance, heat resistance, low temperature strength and mechanical properties, as one of the most widely used types of stainless steel. In addition, it has exceptional hot-workability such as stamping and bending, without leaving heat treatment hardening phenomenon.

304L stainless steel is remarkably similar to 304 stainless steel in their chemical composition with one key difference. the maximum carbon of 304L stainless steel content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. This is why the “L” in 304L can be interpreted as extra-low carbon.

310S stainless steel is austenitic chromium-nickel stainless steel, with good oxidation resistance, corrosion resistance, because of a higher percentage of chromium and nickel, so that it has much better creep strength, with good high temperature resistance.

316 stainless steel also contains 2-3% molybdenum, in addition to iron, chromium and nickel. The addition of molybdenum significantly improves the performance of 316 stainless steel in certain corrosive environments, especially those containing chlorides. 316 stainless steel is more commonly used in situations requiring higher corrosion resistance.

316L stainless steel features a lower proportion of carbon in its composition. The amount of carbon cannot be higher 0.03%. This lowers the risk of carbon precipitation, making it a better option for welding to achieve maximum corrosion resistance.

309 stainless steel is a stainless steel material with excellent corrosion resistance and high temperature performance. It is commonly put into use in aviation, chemical industry, petroleum, food and other fields.

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.
