This chrome-molybdenum alloy steel is specifically engineered for its excellent strength at elevated temperatures. Its composition includes chromium for oxidation resistance and molybdenum for enhanced strength. The material meets stringent mechanical properties, including high tensile strength and superior creep resistance, making it exceptionally durable under stress and heat. The classification into Class 1 (annealed) or Class 2 (tempered) allows for selection based on the specific strength and toughness requirements of your project.
