904L /1.4359 Stainless Steel structure Sections Introduction
  • Super austenitic stainless steel Grade 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is a high-alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in sulfuric acid, acetic acid, formic acid and phosphoric acid. It has good resistance to pitting corrosion in a neutral chloride-containing environment, as well as good resistance to crevice corrosion and stress corrosion. In some cases, its corrosion resistance can be equivalent to that of nickel-based corrosion-resistant alloys, and it is not easy to Corrosion spots and cracks appear, and the resistance to pitting corrosion is slightly better than other steel types. It is mainly used in industrial fields such as petroleum equipment, nuclear power plants, offshore platforms and seawater treatment.
  • PeakKong Special Steel's automated laser welding equipment produces 904L stainless steel structural profiles. The strength of the weld seam is the same as or better than that of the base metal, and the deformation is small. The minimum order is one piece.
