Passivation is the generic term applied to procedures developed to remove the presence of metallic (free) iron from the surface of stainless steel products. The presence of free iron particles on the surface of stainless steel products can cause the product to show rust spots which should not occur with a clean or “passive” stainless steel surface. A PASSIVE stainless steel surface would have NO free iron particles which could potentially corrode or “rust.” In addition to removing heat color our weld cleaning machines simultaneously passivate.
Stainless steel passivation is simple to achieve with our weld cleaning system!
***Capital Weld Cleaners process will achieve chemical passivation on stainless steel in accordance with ASTM A967 specification.
