The composition of this chrome-molybdenum steel is carefully balanced, primarily featuring chromium for enhanced strength and molybdenum for improved heat resistance. This specific alloying results in excellent mechanical properties, including strong tensile strength and good notch toughness, even under demanding conditions. The material is designed to perform reliably at elevated temperatures, maintaining its structural integrity. Products are differentiated by class, with Class 2 undergoing more rigorous normalization and tempering heat treatment to achieve superior mechanical characteristics compared to Class 1.
