(1) The high ratio of Cr, Mo, Ni and N alloy has good resistance to pitting corrosion, crack corrosion, intergranular corrosion and stress corrosion in various acidic corrosive environments containing chloride ions. The [SCALE STEEL]comprehensive corrosion resistance is better than 316L, which is close to nickel-based alloy.
(2) Good mechanical properties, compared with the conventional austenitic stainless steel such as 304,316,317, has a higher tensile [SCALE STEEL]strength, while maintaining excellent material toughness and impact strength.
(3) Excellent welding performance, easy to manufacture and install on site.
Al-6XN alloys are ideal for the following applications:
-- Chemical treatment tanks and pipes
-- Process systems for offshore oil and gas platforms
-- Condensers, heat exchangers [SCALE STEEL]and pipes containing seawater or crude oil
-- Filter washers, vats and press rollers in pulp bleaching plants
-- Flue gas scrubber environment of power plant
-- Tall distillation tower and packaging
-- Desalination equipment and pumps
-- Water piping system for nuclear power plants
-- Transformer boxes exposed to the Marine environment
-- Pharmaceutical equipment (purification)
-- Food processing equipment
