This particular chrome-molybdenum alloy steel is defined by its composition, primarily chromium and molybdenum, which gives it excellent strength and resistance to corrosion and oxidation. Mechanically, it is designed for high-temperature service, maintaining its integrity under stressful conditions. The distinction between Class 1, which is supplied in the normalized condition, and Class 2, which undergoes normalized and tempered treatment, allows engineers to select the precise properties needed for their specific pressure and temperature requirements.
