摘要
介绍了低合金高强度结构钢SM 5 70不同热处理制度下的机械性能、低温冲击 ,并检验分析了该钢的显微组织、夹杂物及晶粒度。结果表明 :研制的SM 5 70钢板的各项性能均满足标准要求 ,特别是低温冲击韧性较好。
The mechanical property at various heat treating systems and low temperature serial impact test of low alloy high strength structural steel SM570 are described. The microscopic structure, inclusion and crystalline grain size of the steel are inspected and analyzed. The result indicates that properties of SM570 steel plate meet the standards, low temperature impact toughness, in particular, is better.
