摘要
This paper briefly introduces the process of the hydrocracking reactor made of the steel 1 25Cr-0 5Mo -Si,analyzes the weldability of the steel,make measures to prevent the welds from cold cracking、reheat cracking and temper embrittlement,makes out the optimum parameters and the procedures that make the complete product meet the requirement of mechanical properties.
