一、前言目前国内生产的16Mn钢板,普遍存在两个问题:一是强度低韧性合格,二是韧性低强度合格。太钢生产的热轧16Mn钢板主要是屈服强度及强度极限低于标准要求,每年约有15％的次品,每吨钢板削价约300多元,如果把合格率提高到95％,一年生产16Mn钢板约3.5万吨,仅此一项一年便带来巨大的经济效益。另外,有些热轧16Mn钢板要求正火状态交货,正火后屈服强度要降低,合格率还 I. Preface At present, 16Mn steel produced domestically has two problems: one is low strength and the other is toughness and low strength. The hot-rolled 16Mn steel produced by TISCO is mainly below the standard yield strength and strength limit. Each year, about 15% of defective products are cut by about 300 yuan per ton of steel plate. If the pass rate is raised to 95%, the annual production of 16Mn About 35,000 tons of steel, this one alone will bring huge economic benefits. In addition, some hot-rolled 16Mn steel requires normalized delivery, normalizing the yield strength to be reduced, the pass rate also
