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.

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.

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.

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

DIN 17175 is a standard specification for seamless tubes of heat-resistant steels used in elevated temperatures and high-pressure environments.

This standard applies to seamless steel tubes for general structural and mechanical structures. The main production of steel pipe grade includes Gr 10, Gr 20, Gr 35, Gr 45, Q345, 15CrMo, and 12Cr1MoV.

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.

ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.

A213 is a ferrite and austenitic alloy seamless steel pipe for boilers, superheaters and heat exchangers. Its products should comply with TSG D7002 pressure piping component type test rules.

A179 seamless cold drawn low carbon steel pipe is equivalent to China's No. 10 high-quality low-carbon steel. A179 is suitable for cold-drawn high-quality low-carbon seamless steel pipes for heat exchangers and condensers.

Grade S355 is a low carbon manganese-containing steel alloy. This medium-strength carbon steel has both good weldability and good impact resistance. Grade S355 steel is also well suited for sub-zero temperature applications.

ASTM A335 steel pipe may be hot finished or cold drawn and subjected to the following finishing heat treatment. The specification covers "chrome-molybdenum" seamless pipes with excellent corrosion resistance and high temperature tensile strength.
