30X13 EJ3 1.4028 420F X30Cr13 Delivery from the stock, in stock


Steel of martensitic class 30X13 has mainly iron and chromium in its composition. According to GOST 5632-72, the composition of 12-14% Cr, 0.26-0.35% C. Alloy is alloyed with silicon and manganese 0.8% each, nickel up to 0.6%, copper 0.3%, titanium 0.2%, thousandths of phosphorus. The remainder is iron. Substitute: 40X13.
