ALTA SPECIAL STEEL supply DIN 1.2738 / AISI P20+Ni in round bar, plate, square and block.
Chrome-manganese-nickel-molybdenum steel for hardening in air or in oil with good hardenability and good firmness during the heat. It is well-workable during the heat and well-workable in the soft-annealed state and it has good polishability. The steel has a high ability of the heat treatment into big depths (better than DIN 1.2311) with the balanced process of firmness around the whole cross-section. It is appropriate for nitriding and hard-chroming.
