S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, 30MnB5 alloy steel for quenching and tempering, the abbreviated designation of this delivery condition shall be AR (As rolled).
40Cr steel belongs to alloy structural steel. 30MnB5 alloy steel for quenching and tempering, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as 30MnB5 alloy steel for quenching and tempering. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of 30MnB5 alloy steel for quenching and tempering, NM500 wear plate is 70mm.
