ASTM A709 Grade 36 Low-alloy Steel Plate

ASTM A709 steel plate is a carbon, high strength low alloy and quenched and tempered alloy steel primarily used in bridge construction.

American standard bridge structural steel A709 Gr36 is A709M Gr36. The two are the same grade, one metric unit and one imperial unit. The one with "M" is the metric unit standard, and the one without the letter "M" is the imperial unit standard. A709 Gr. 36 futures fixed rolling, guaranteed material and performance, spot inventory cutting and processing, cutting and blanking according to drawings, guaranteed material and performance, and original factory corresponding quality certificate provided.

ASTM A709 gr.36 high strength alloy steel plate composition characteristics

(1) Low carbon: Due to the high requirements on toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%.

(2) Add alloying elements mainly manganese.

(3) Add auxiliary elements such as niobium, titanium or vanadium: A small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtaining fine ferrite grains and improving the strength and toughness of the steel. . In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, and improve toughness and process performance.
