Characteristics of Stainless Steel 904L material:

Excellent corrosion resistance: 904L exhibits extremely high corrosion resistance in various corrosive media, including sulfuric acid, phosphoric acid, and organic acids.

Good resistance to pitting and crevice corrosion: Especially in environments containing chloride ions, 904L exhibits superior resistance to pitting corrosion.

Non magnetic state: Non magnetic in annealed state, making it suitable for specific magnetic requirements.

High strength and good processing performance: Even under high temperature conditions, 904L maintains good strength and plasticity, making it easy to process and weld.


Application Area:

Chemical industry: Due to its excellent corrosion resistance, 904L is commonly used in chemical equipment, pipelines, heat exchangers, and storage tanks.

Oil and gas: suitable for equipment manufacturing in corrosive oil and gas environments.

Pharmaceutical industry: used for production equipment that meets high standards of hygiene and cleanliness requirements.

Ocean engineering: Due to its resistance to saltwater corrosion, it is commonly used in seawater treatment equipment and marine facilities.
