Abrasion resistance weld for 2.25Cr-1Mo Valve Bonnet
Abrasion resistance weld for 2.25Cr-1Mo Valve Bonnet
(OP)
Hi there,
I've got steam letdown valve ofwhich the bonnet is made of 2.25Cr -1Mo.
The internal of the bonnet has scouring marks due to the piston ring rubbing against the inside of the bonnet.
Will Ni Cr 3 (Inco 82) weld rod be a suitable material to be used for the repair (to resist further abrasion)?
How do I confirm this?
Thanks.
