Chung Metals is a trusted manufacturer and supplier of premium metal products based in Da Nang, Vietnam. Specializing in bulk stainless steel, they are known for their expertise in supplying thin 904L stainless steel. These thin plates are known for their exceptional corrosion resistance, making them ideal for use in chemical, petrochemical, marine and other industries Chung Metals is committed to providing its customers with industrial solutions if durable, reliable and accurate for all their steel needs.
Stainless steel 904L is a strong austenitic stainless steel composed primarily of steel, with nickel (25-28%), chromium (19-23%), molybdenum (4-5%), and copper ( 1-2%) per hour. These properties increase corrosion resistance, especially in acidic environments. The mechanical properties of 904L include high tensile strength (close to 520 MPa), yield strength (close to 200 MPa), and elongation (up to 40%), resulting in excellent durability Provides resistance to pitting and crevice corrosion well in applications in chemical , marine and aerospace industries It is the best.

Stainless Steel 904L Flat Bar is widely used in chemical processing, oil and gas, marine, pharmaceutical, and pulp and paper industries due to its exceptional corrosion resistance, particularly in acidic, chloride-rich, and high-stress environments.
Stainless Steel 904L offers superior corrosion resistance compared to standard austenitic stainless steels, excelling in harsh environments with strong acids (sulfuric, phosphoric) and chloride exposure, due to its high nickel, chromium, and molybdenum content, reducing pitting and stress corrosion.
Yes, Stainless Steel 904L Flat Bar is highly suitable for marine environments due to its excellent resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking, making it ideal for shipbuilding, seawater equipment, and coastal structural applications.
Thin stainless steel 904L Bar are widely used in applications requiring high corrosion resistance. Because of their excellent acid resistance, they are ideal for pharmaceutical, petrochemical and pharmaceutical industries. Typical applications include heat exchangers, reagents, pressure vessels, and piping. Due to its resistance to chloride-induced stress, the material is used in marine environments, offshore platforms and desalination plants in addition to 904L flat pads in decontamination equipment, food processing and aerospace industries in 1999, where durability and resistance are required
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
