[MW:2305] RE: 2298] Cr. cabide exothemic in SS cladding

Ss 309l WELD overlay can be good only in case of CS base metal where PWHT is
restricted at 600-620C but incase of PWHt at 690 and above for overlay or
restoration of cladding you have to use inconel weld i.e. use ENiCrFe2 or
ENiCrfe3 and for Tig process use ER NiCr3 This will definitely serve your
purpose w/o failure in bend
