Through optimizing designs of carbon, manganese, silicon elements and proportion of carbon and manganese and carbon equivalent, controlling carbon content within 0.18%-0.22%and manganese content within 1.22%-1.32%and the ratio of manganese/carbon≥6, the Lcc-1 valve was developed by reasonable design for heating treatment process. The tests showed that the all properties of trial products met the standard requirements. The composition and process design is rational and feasible. Adopting the quenching and tempering treatment, the products have been mass production, and the once inspection pass rate run up to more than 98%.
