How can avoid carbon absorbtion in stainless steel lost foam casting?

05 May 2015 1 5K Report

The melt has 0.06 % carbon but after casting the result comes out with 0.2% carbon.

Dear R. Sadeghi

Low carbon stainless steel parts are formed utilizing a high vacuum of 20" to 29" of mercury during the pouring stage of the lost foam process.

Please See this

(Lost foam process for casting low carbon stainless steel

Publication number US5429172 A)

Good luck
