Carbon and Low-alloy High-strength Steel steels are not typically made to meet a certain chemical composition, instead they are known to meet specific mechanical properties. They are intended primarily for use in structural fabrications. All-Win steel Carbon and Low-alloy High-strength Steel main steel grade:Q235B, Q355B, S235JR, S355JR, A36 Differences between A572Gr50 Steel and Q345 Steel steel 1.A572Gr50 Steel and Q345 Steel Description A572Gr50 steel is a kind of high-strength low-alloy columbium-vanadium structural steel. 8 to 300 mm A572Gr50 steel plates is widely used in engineering structures, such as construction steel structures, construction machinery, mining machinery, trucks, bridges, pressure vessels, etc., especially for better weldability And tough construction and
Steel Standard:GB/T1591 Rolling Type:High strength low alloy structural steels Thickness:6mm-350mm Width:1500mm-4200mm GB carbon and low alloy steel- GB/T 1591 Q460D low . There are three quality grades under Q460 series steel:Q460C, Q460D and Q460E. Density of this steel is 7.85 g/cm³. Q460D GB low alloy steel tensile strength is 550-720 MPa; the yield strength is minimum 460 MPa when thickness less than 16mm. For Q460D s.
