The exterior parts of our stainless steel silencers are made from Grade 304 stainless steel. The perforated internals are made from Grade 409 or equivalent. Our stainless absorption silencers have a primary lagging of stainless steel wool. Any moisture retention in the silencer does not result in any corrosion as no mild steel is used in the construction.
