Application of 45# steel

45# steel is one of the most widely used steel, almost all heat treatment workers have dealt with it, most colleagues think that 45# steel is a very difficult "opponent", water quenching is easy to crack, oil quenching is not hard. The 45# steel is mainly used for manufacturing all kinds of forgings. Heavy forgings can be used under normalizing condition, and can also be quenched and tempered; Small forgings are basically quenched and tempered. According to the need, it can be tempered at low or medium temperature after quenching.

With the development of national economy and the demand of export-oriented economy, 45# steel is not only used to manufacture various components in engineering, but also can be used to manufacture low-grade molds, slow cutting taps, dies and other tools. It can also be used to manufacture steel wire pliers, spanners, screwdrivers, hammers and other five metal tools, as well as various garden tools and agricultural machinery tools.
