22%Cr-12%Ni 不锈钢和碳钢的异种金属焊接 , |
Applications
MIG welding of 22%Cr-12%Ni steel, heat resistant cast steel clad side of 18%Cr-8%Ni clad steel
and stainless steel to Cr-Mo steel or carbon steel.
Applications
Characteristics on Usage
As the weld metal contains ferrite, its crack resistibility is good. Due to its high level of alloy, it has
excellent resistance to heat.
