Hi All
We have 2 small castings (pump heads) to repair (porosity). Please could anybody with experience in this material give me some pointers in how to repair. I have looked online and pre-heat and post-weld treatment is favoured but as these are only localized repairs, do I need to do the fore mentioned.

Bohler make a rod specifically for welding this..its called BOHLER FOX CN 16/6.......I would have a word with them about it.

With it being a soft low carbon martensite you can probably get away without preheating for welding, however, I dont think ive ever seen it welded so I cant claim any experience.

Talk to Bohler in Hamm, Germany.
