Patent
CA 2043146
The invention relates to a precipitation-hardenable tool steel intended for plastic forming tools manufactured therefrom. The tool steel at the manufacturing of the tool and prior to hardening through ageing treatment but after solution heat treatment and cooling to room temperature has a hardness less than 40 HRC, but after the manufac- turing of the tool and the subsequent age hardening treatment, i.e. in the precipitation hardened condition, is harder than 45 HRC and has a high corrosion resistance and a toughness sufficient for plastic forming tools. The steel contains in weight %: max 0.08 C, max 1 Si, max 2 Mn, 9 - 13 Cr, 7 - 11 Ni, max 1 Mo, 1.4 - 2.2 Al, and balance being essentially only iron, impurities and accessory elements in normal amounts.
