摘要
本文对加氢反应器用 3Cr - 1Mo - 1 /4V -Ti -B钢母材与焊缝金属的化学成分、力学性能、脆性转变温度进行了测定 ,结果表明该材料与常规Cr -Mo相比其综合性能优越、抗回火脆化性能好 ,能满足高温高压大型热壁加氢反应器制造要求。
In this paper,we measured the mechanical properties,chemical compositions and temper embrittlement of 3Cr-1Mo-1/4V-Ti-B steel and welding.The results show that properties of this steel are better than general Cr-Mo steel and the resistence of temper embrittlment is excellent.This steel can meet the need of large hydrogenation reactor working under high temperature and pressure.
