904L is a high-alloy austenitic stainless steel with low carbon content. 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.
It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid.
Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes.
Alloy 20 is used is a wide variety of applications from Sulfuric acid pickling tanks, racks and heating coil, Heat Exchangers, Process piping, Chemical and petroleum process equipment etc.
alloy 59 (UNS N06059) having a typical chemical composition of 59% nickel, 23% chromium, 16% molybdenum and iron levels of less than 1%, appears to have fulfilled this need.
Alloy 59 have shown excellent resistance to localized corrosion, hydrogen embrittlement and stress corrosion cracking while possessing very high strength, ductility, fracture toughness, high-cycle fatigue resistance and very low crack growth rate both in air and sea-water.
