Weldable, hard stainless for mixer blades

Weldable, hard stainless for mixer blades

(OP)
Hi All:

Looking for reasonably weldable, hard stainless for mixer blades.  Considered 440C for hardness but weldablility is questionable. 17-4 may be the choice....but trying to get away from post-weld heat treating.

Any suggestions?

430?
17-4?

RE: Weldable, hard stainless for mixer blades

The post weld aging treatment is why 17-4 or 17-7 would be a good option.  You could work from annealed material, weld and then age.

How hard of a material do you need?  There are always the duplex grades.
