American standard H-beam A992 is a high-strength low-alloy steel that meets the ASTM A992/A992M standard. It has excellent mechanical properties and weldability, and is widely used in the manufacture of heavy-duty structures and large buildings. The tensile strength of A992 H-beam is 345MPa, the yield strength is 450MPa, and the elongation is 18%.

A572GR50 is also a high-strength low-alloy steel that meets the ASTM A572/A572M standard. It has good weldability and plasticity, and is widely used in the manufacture of bridges, buildings and mechanical equipment. The tensile strength of A572GR50 H-beam is 450MPa, the yield strength is 345MPa, and the elongation is 21%.

American standard H-beam materials include A36, A572, A709, A992, A913, Q355B, etc.

ASTM A992/A572 Grade 50 Steel Beam and Channel

ASTM A992 (A572 Grade 50) steel is the most used construction-based structural steel in existence. It is used to make I beams, Wide Flange, channels, plates, angles, and other shapes. ASTM A992 structural steel contains small amounts of vanadium or columbium, copper, nickel, chrome, and molybdenum, which provide increased material definition.

A572 Grade 50 Steel Certification

In most cases, ASTM A992 steel can be dual-certified to A572 grade 50, exhibiting the high strength and improved weight-to-strength found in A572 carbon steel. Since A992 welds easily, it is often used to fabricate structural steel components where high corrosion resistance is required.
