Speical Alloy Forged Steel is widely used in cold making die steel, with high strength, better hardenability and good wear resistance, but the impact toughness is poor.It is mainly used for the low impact load, which requires high wear-resisting cold punching die and punch, cold cutting scissors, drill sleeve, gauge, drawing die, embossing die, thread rolling, drawing die and thread rolling mould.
The steel has good hardenability, abrasion resistance, hot workability. Carbide distribution in the steel is good, can be used to make complex shape, heavy working conditions of all kinds of cold work mould. Such as cold die punch, thread rolling dies, wire drawing die, die, powder metallurgy die, woodworking cutting tools, cold cutting scissors drill tool and gauge set.
