What is ASTM A572 equivalent to?
ASTM A572 steel plate is a popular grade of high-strength low-alloy (HSLA) steel that is typically used in structural applications. A572 steel contains chemical alloys that enhance the material's hardness and ability to bear weight, and this material is lightweight relative to steel grades with similar compositions.
Steel plate ASTM A572 Grade 50, equivalent to national standard Q345B, Japanese standard SM490, European standard S355JR,ASTMA572-55 corresponds to the national standard is A572 G42,
ASTMA572-55 corresponds to the national standard is A572GR42, A572Gr60/65 steel plate belongs to the American standard high-strength low alloy niobium-vanadium structural steel plate. The grades are ASTMA572Gr60, Gr65, corresponding to the national standard Q420B, Q460C steel plate, the steel has a low carbon and low silicon, high strength, high toughness, through the control of trace elements.
A572 steel comes in five different grades: 42, 50, 55, 60 and 65
A572 steel is commonly used in structural applications due to its high strength, ductility, weldability, and corrosion resistance. These applications include structural shapes, rebar, bridges, skyscrapers, and houses.
