Two prehardened tool steels for plastic molds are offered by Hasco America Inc., Arden, N.C. Toolox 33 is a prehardened, tempered steel with exceptionally low residual stresses and high toughness for nearly distortion-free machining, Hasco says. Toolox 44 is prehardened to 45 HRC, which eliminates pre-machining and heat treatment. Both steels can be gas-nitrided and PVD-coated, since they can withstand up to 1094 F (590 C).
