0.5Ni Chemical CompositionAmong the main factors affecting the brittle transition temperature of 0.5Ni steel, the content of alloying elements and impurities are closely related to the chemical composition.
Influence of various alloying elements: C carbide precipitation will cause porosity, which is generally controlled at <0.08%; Mn austenite phase stabilizes elements to improve wear resistance and nitrogen solid capacity; Si contributes to high temperature oxidation resistance and acid etching resistance; Ni stabilizes the element, reduces brittleness and improves mechanical properties, and enhances acid resistance. <b114>
