US $5.00-$100 acid pickling 304 welded stainless steel pipeYour Guide to Stainless Steel PassivationOn a side note, its important to know the exact alloy of stainless steel being processed prior to picking your passivating process. This is because using the wrong solution on your stainless steel could cause damage to the steel rather than enhancing it. For example, compare 304 vs 430 stainless steel for passivation processes. Each of these allows have different levels of resistance to nitric acid and other corrosives, which means that one might need a stronger nitric acid Why stainless steel pipe needed Acid Pickling and acid pickling 304 welded stainless steel pipeSep 22, 2017 · 1,Pickling removes both weld oxide and stainless steel But passivation does not remove weld oxides not attack stainless steel. 2,Pickling are typically hydrofluoric, sulphuric (or in steel mills,hydrochloric) acid. It utilizes more aggressive acids than those used in passivation.Passivation are Nitric acid or electropolishing.
