摘要
介绍了低合金高强度结构钢SM5 70不同热处理制度下的机械性能、低温系列冲击 ,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 。
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.
