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.

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.
