摘要
通过合理地控制成分,运用微合金化原理,结合控轧控冷工艺措施,使低合金高强度Q345系列钢种低温冲击韧度有明显改善,采用合理热处理工艺可完全保证其低温冲击韧度的要求。
Impact ductility of Q345 series steel was improved by controlling composition,adopting micro-alloy theory and controlled rolling controlled cooling technics.The impact ductility request can be satisfied by adopting reasonable heat treatment process.
