s 45 c, sa36, S235JR mild steel sheet, The wear-resistant composite plate is quenched once and tempered at low temperature. The quenching temperature is 820-850℃ or 780-810℃. If the strength of the core is required to be higher, it should be quenched at 820-850℃ with low carbon M at the core. If the surface hardness is required to be high, the grain size can be refined by quenching at 780-810℃. It is suitable for solid carburized carbon steel and low alloy hardfacing wear-resistant composite plate workpieces, and coarse grain steel carburized by gas and liquid.
s 45 c, sa36, S235JR mild steel sheet, 13CrMo44 steel plate is a kind of steel which with Cr, Mo,Cr-Mo and mainly used for pressure vessels. The steel grade 13CrMo44 is according to DIN 17155 standard which with the yield strength of 242MPa. The DIN 17155 13CrMo44 steel plate chemical composition is the content of C is 0.15, Mn is 2.00, S is 0.03, Cu is 0.30, Si is 1.00, P is 0.045, Cr is 17 or 19 and the Ni is 8 or 10.
