Heat strain embrittlement in welding low alloy structure steels
低合金结构钢的焊接热应变脆化
The problems of welding austenitic heat resistant steels ( HR3C 、 NF709 、 Super304H) are hot cracks, embrittlement after aging and stress corrosion.
HR3C、NF709、Super304H等奥氏体钢的焊接问题是热裂纹、时效脆化和应力腐蚀。
By restoring heat treatment, hardness can be decrease, impact toughness can be increase and embrittlement of bolts can be eliminated.
经过适当的恢复热处理，可使脆化螺栓的硬度降低、冲击韧性升高，重新满足使用要求。
For the bolt material, heat treatment and hydrogen embrittlement sensitiveness testing and mechanical testing were conducted.
对螺栓材料进行了热处理、氢脆敏感性和力学性能试验。
The technique to assure product quality and avoid of heat embrittlement are put forward.
提出了为保证产品质量、避免热脆性应采用的技术；
Compared with ordinary steel, the weldability of hot-stamped steel is greatly different, and there are many other problems during the welding process, such as softening of heat affected zone, embrittlement of nugget, splashing and so on.
与普通钢板相比，热成形钢电阻点焊可焊性有很大的差异，且在焊接过程中会遇到热影响区软化、焊核脆化、容易产生焊接飞溅等一系列问题。
