In recent years, in line with the development trend of iron and ASTM A709 high strength steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which ASTM A709 high strength steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
The boiler and pressure vessel steel plates are our main products. Our main conducted standards for boiler and pressure vessel steel plates are (ASME) ASTM (S)A202, (S)A203, (S)A204, (S)A285, (S)A299, (S)A302, (S)A387, (S)A515, (S)A516, (S)A517, ASTM A709 high strength steel, (S)A533, (S)A537, (S)A612, (S)A662, (S)A841, EN10028-2, EN10028-3, EN10028-5, EN10028-6, JIS G3115, JIS G3103, GB713, GB3531, DIN 17155, JIS G3116, GB6653, EN10120, etc. Our typical boiler and pressure vessel steel grades are A204 grade B, A516 grade 70, A537 class 1, A537 class 2, 16Mo3, Q245R,Q345R, etc.
ASTM A709 high strength steel, 30CrMnSiA steel plate is a kind of low alloy high strength steel with medium carbon, high strength and good weldability. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. After quenching and tempering, 30CrMnSiA steel can be used as grinding wheel shaft, gear and sprocket. 30CrMnSiA steel has good processability, small deformation and good fatigue resistance. 30CrMnSiA steel is usually used for shaft, piston parts, etc. It is used for various special wear-resistant parts of automobiles and airplanes.
Vanadium is a weak deoxidizer. Adding vanadium into ASTM A709 high strength steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.
ASTM A537 class 1 boiler plate is pressure vessel steel. ASTM A709 high strength steel, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.
