The strength of this chromium-molybdenum steel lies in its careful composition, which includes chromium for enhanced strength and molybdenum for improved temperature resistance. This specific alloy is designed to perform reliably in elevated temperature service, offering excellent tensile strength and notch toughness. The “Class 1” and “Class 2” designations refer to the heat treatment, with Class 2 undergoing a more rigorous normalization and tempering process for superior mechanical properties suitable for even more demanding applications.
