Water, Seawater, Desalination & Marine - Water Distribution and Treatment

ATI Allegheny Ludlum's stainless steels have many applications in water and wastewater treatment facilities. These include aeration pipes, digester gas pipes, sludge transfer pipes, agitators, tanks, screens, filters, slide gates, ozone reactors, chlorine and ozone mixing towers, and ultraviolet disinfection reactors. Type 316L is the most commonly used grade in water treatment facilities, but the AL 2003™ lean duplex alloy offers strength and corrosion resistance advantages compared to Type 316L at a comparable cost. Type 304, Type 316, and AL 2003™ stainless steels may also be used for potable water distribution and can offer considerable life-cycle cost savings over traditional materials, such as ductile cast iron.
