AL29-4C alloy is a stainless steel designed by Allegheny Ludlum (www.alleghenyludlum.com) for extreme resistance to corrosive condensates created by partially or fully condensing natural gas- and propane-fired heating appliances where cool flue gases are vented under pressure. The Canadian Gas Research Institute found that test results proved AL29-4C to be one of the "most corrosion-resistant alloys of 20 candidate stainless steels evaluated for resistance to chloride-induced corrosion in condensing and partially condensing gas-fired appliances."
