1.25Cr-0.5Mo | 1.25Cr-0.5Mo-Si

Chemical Composition & Characteristics The 1.25Cr-0.5Mo (also known as “1-1/4Cr-1/2Mo”) steel is a typical low alloy heat-resistant steel of the Cr-Mo steel family. It is widely used for applications at elevated temperatures. The figures “1.25” and “0.5” denote the nominal chemical composition of chromium and molybdenum alloying elements respectively. The chromium provides improved oxidation and corrosion resistance, and, the molybdenum …

The Heat-Resistant Chromium-Molybdenum Alloy Steels

Chemical Composition & Applications The heat resistant chromium-molybdenum alloy steels refer to a series of ferritic alloy steels that feature deliberate addition of chromium and molybdenum alloying elements. It usually contains 0.5% to 9% Cr and 0.5% to 1.0% Mo, which in combination impart improved creep strength and corrosion resistance at elevated temperatures to the alloy steels. This is the …
