摘　　要：设计并冶炼了三种B含量不同的SA-336-F11 CL3钢锭,测定三种钢的临界点和CCT曲线,制定相应的模拟热处理工艺,通过对比金相组织,分析不同B含量对钢淬透性和组织的影响。Three kinds of SA-336-F11 CL3 ingots with different B contents have been designed and smelted,and the critical point and CCT curve of the three kinds of steels have been measured,and the corresponding simulated heat treatment process has been developed.By comparing the metallographic structure,the influence of different B contents on the hardenability and microstructure of steel has been analyzed.

关 键 词：B含量 CCT曲线 淬透性 金相组织 高温承压用合金钢
