A36 is an American standard carbon structural plate, which is subject to ASTM A36/A36M. This standard is applicable to riveting, bolting and welding structures for bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and bars.
S355 is a European-standard, high-strength low-alloy (HSLA) structural steel, characterized by its medium tensile strength, excellent weldability, and guaranteed impact resistance at sub-zero temperatures. Governed by the EN 10025 series of standards, it offers a superior strength-to-weight ratio compared to standard carbon steels like S235 and S275, making it a premier choice for critical welded and bolited structures in demanding environments.
ASTM A283 is a standard specification for low and intermediate tensile strength carbon steel plates of structural quality for general application. It covers four grades (A, B, C, D) with incrementally higher minimum yield and tensile strength requirements. Q195 is a comparable Chinese standard (GB/T 700) grade, often supplied as an equivalent.
ST12 is German standard (DIN1623), It's ordinary cold rolled steel. In principle, ST12 can only be bent and formed, and no stamping is allowed.
AH36 is a high-strength shipbuilding steel plate, one of the most common grades used in marine and offshore structural applications. It is strong, tough, and offers good weldability and formability to meet the demands of ship construction. As a grade that requires classification society certification (e.g., ABS, LR, DNV), it is important to know its key attributes, which include a minimum yield strength of 355 MPa (51 ksi) and guaranteed impact toughness at low temperatures.
NM500 is a high-strength, wear-resistant / abrasion resistant steel plate specified in the Chinese national standard GB/T 24186. NM500 is known for its superior hardness and durability. This steel is specifically designed to withstand severe abrasive wear conditions to provide extended service life in challenging industrial environments.
S275JR is a non-alloy structural steel plate according to European standard EN 10025-2. It offers good strength, excellent weldability and formability, making it a versatile and commonly used material for general structural applications. Typical uses include: manufacturing plants, machinery frames, construction, various equipment, and other structural components.
SPCC is a commercial quality cold rolled steel sheet/plate as per JIS G 3141 standard. It is generally used for parts requiring bending, pressing, or moderate forming, and is commonly applied in automotive bodies, appliances, cabinets, and general metal products. It does not have inherent good atmospheric corrosion resistance and typically requires surface protection (e.g., painting, plating) for exterior use.
NM400 wear-resistant carbon steel plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, etc. It is also commonly used as high-strength structural steel with yield strength ≥ 800MPa.
SA516Gr. 70 is widely used in petroleum, chemical industry, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, water turbine shells and other equipment and components.
