Re: [MW:3683] Re: Cold form dish

Dear Anant,

5% fibre elongation is the limit for Carbon and low alloy steel. For stainless steel it is 15-20%. We have to refere UHA-44 and table UHA-44 where the requirement are clearly mentioned.

Hope this will help to make decision.

Dear Pl. check what percentage elongation is coming while cold forming if it is more than 5 % you have to do heat treatment.
