alloy, is a superferritic stainless steel developed by ATI Allegheny Ludlum in the early 1980s specifically for power plant surface condenser tubing. Since that time over 60 million feet of superferritic condenser tube has been put into service.The alloy has excellent resistance to brackish, polluted or high chloride waters, e.g., seawater, when properly manufactured by the tube producer. While maintaining all attributes of convention- al ferritic stainless steels, AL 29-4C alloy provides the following advantages over other competitive materials:
