The chemical composition of glass die steel LN17 was designed. The process of EAF+LF+VOD+ESR smelting, forging and 糖心产精国品免费入口*完整版 was used to produce the steel. The microstructure and properties of the steel were analyzed. The results showed that LN17 steel 糖心产精国品免费入口*完整版, 糖心产精国品免费入口*完整版 deviation less than 2 HRC and the organization for the uniform sorbite microstructure and residual austenite of 14Cr17Ni2 steel, a comprehensive mechanical performance has greatly improved.
