Kanish Metals is a reputable producer and distributor of Stainless Steel 904L Flat Bars in Dubai, UAE. Stainless Steel 904L is an austenitic stainless steel alloy with superior corrosion resistance, even in severe environments like those that include chlorides and sulfuric acid. We provide 904L flat bars in different sizes and specifications to meet the needs of a broad spectrum of industrial applications with better performance, strength, and long-term reliability. Our products are produced with the finest quality standards so that they can fulfill the requirements of industries like chemical processing, marine, and pharmaceutical.
Stainless Steel 904L consists of approximately 20-23% chromium, 25-30% nickel, and 4-5% molybdenum, along with other elements such as copper and manganese. This alloy provides 904L superior resistance to stress corrosion cracking, crevice corrosion, and pitting, especially in acidic exposures. It exhibits outstanding resistance to sulfuric acid, phosphoric acid, and chloride bearing surroundings. The alloy exhibits superior tensile strength up to 100 ksi and good toughness at both low and high temperatures. Stainless Steel 904L has a hardness of around 220-300 HB and also possesses excellent weldability as well as formability.

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.
904L Stainless Steel Flat Bars are extensively utilized in industries that require high corrosion resistance along with outstanding mechanical properties. The flat bars find frequent use in chemical processing facilities, especially in equipment that gets exposed to corrosive conditions like acid environments, viz., reactors, heat exchangers, and piping systems. 904L flat bars are also employed in the marine sector for seawater applications, and for use in desalination plants due to their chloride-induced corrosion resistance. They are also employed in pharmaceutical and food processing industries, where hygiene is critical, along with resistance to corrosive media. The high performance of 904L makes it perfect for both industrial and critical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
