  in the topic SM45 steel in the forum Off-Topic Discussions

  SM45 steel is a high-quality carbon plastic mold steel. Compared with high-quality 45 carbon structural steel, the content of sulfur and phosphorus in the steel is low, and the purity of the steel is good. Due to the poor hardenability of the steel, the production of large-sized plastic molds is generally hot-rolled, hot-forged or normalized. The hardness of the mold is low and the wear resistance is poor. For the manufacture of small plastic molds, high hardness and good toughness can be obtained by quenching and tempering. The carbon content in steel is high, and cracks are prone to occur in water quenching, and oil quenching is generally used. The advantages of this steel are low price, good machining performance, high hardness after quenching, good strength and toughness and certain wear resistance after quenching and tempering. plastic mold.
