Nitrogen Steels and High?Nitrogen Steels: Industrial Technologies and Properties

Nitrogen pressure during melting can be a basis for the most general classification of steels alloyed by nitrogen. are made under normal pressure, and high-nitrogen being higher atmospheric in special units. Nitrogen, as well carbon, strengthens increases thermal stability austenite. The smaller size nitrogen ion compared with carbon results nitrides, lower surface energy strengthening effect, ability to increase both strength corrosion resistance Herein, mechanisms influence on properties steel, thermodynamics kinetics alloying nitrogen, critical concentration considered. Examples steels, including weld joints, properties, such corrosion-resistant bioactive environments, bactericidal C + N, given.
