ASTM A202 grade is divided into: A, B, boiler vessel plate is mainly used for welding boilers and other pressure vessels. There are two grades of ASTM A202 boiler vessel steel: Grade A and Grade B. The thickness of ASTM A202 boiler vessel plates is limited to 2 inches.

EN10025-2 steel plate is a low-alloy high-strength structural steel, which is made of carbon structural steel by adding a small amount of alloying elements.

DIN 17100 ST37 is a carbon structural steel widely used in construction, machinery and manufacturing industries. It has good mechanical properties and can be used to manufacture various mechanical parts.

ASTM A514 steel is available in several grades: A, B, C, E, F, H, J, K, M, P, Q, S, and T, all of which have the same mechanical properties. ASTM A514 steel plates are conventionally quenched and tempered steel. ASTM A514 steel plate is known for its high yield strength, weldability and toughness. ASTM A514 steel is a special high-strength steel, mainly used as building structural steel.

A36 is a carbon structural steel plate whose chemical composition and mechanical properties comply with American ASTM standards. This kind of steel plate has good mechanical properties, welding performance and corrosion resistance, and is widely used in construction, bridges, machinery manufacturing and other fields.

ASTM A588 steel is classified into Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.

ASTM A633 steel includes four grades: A, C, D, and E, of which 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 plate, which requires high notch toughness under low temperature conditions.

316L stainless steel has a lower proportion of carbon in its composition. To qualify as 316L stainless steel, the amount of carbon cannot exceed 0.03%. This decreases the risk of carbon precipitation, making it a better option for welding to ensure maximum corrosion 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.

440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, the highest strength, hardness and wear resistance of all the stainless alloys after heat treatment

201 stainless steel generally refers to 201 stainless steel and acid resistant steel. 201 stainless steel refers to 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.

301 stainless steel is an austenitic stainless steel with a chemical composition of 17 percent chromium and 7 percent nickel, which provides good strength and ductility when cold worked. Besides, it also has excellent corrosion resistance properties.
