Re: [MW:16838] SS-304L Cladding on Inner Dia. of Carbon Steel ring

Dear,

Plz confirm,the Heat treatment of Cladded ring is necessary , my production engineer has recommended that we can use a local arrangement to cool the Ring at the time of cladding.

Cooling arrangement shall be - Water cooled by dipping the ring in the water tub.Heat is absorbed  by cooling water.

Plz recommend is it possible.
