Polished 904l Stainless Steel Round Rod N08904 10mm - 300mm Corrosion Resistant

Polished Round Rod 904L N08904 Stainless Steel Rod 10-300mm Corrosion Resistant

904L stainless steel is a super austenitic stainless steel with excellent corrosion resistance and other superior properties. It belongs to the category of high alloy stainless steel and contains a large amount of alloying elements. The combination of these elements makes it perform well in various corrosive environments.

Since the carbon content of 904L is very low (maximum 0.020%), no carbide will precipitate under normal heat treatment and welding. This eliminates the risk of intergranular corrosion after general heat treatment and welding. Due to the high chromium, nickel, and molybdenum content and the addition of copper, 904L can be passivated even in reducing environments such as sulfuric acid and formic acid.

904L stainless steel performs well in various corrosive environments, especially in acidic environments:

• Non-oxidizing acids: Excellent corrosion resistance in sulfuric acid, acetic acid, formic acid, and phosphoric acid.
• Chloride ion media: Superior resistance to pitting and crevice corrosion in seawater and chloride solutions.
• Other acids: Better performance than conventional stainless steel in industrial phosphoric acid and hydrochloric acid.

904L stainless steel is widely used in various applications requiring high corrosion resistance:

• Petroleum and petrochemical equipment (reactors, heat exchangers)
• Power plants (flue gas desulfurization devices, absorption towers)
• Chemical equipment (seawater treatment, papermaking, pharmaceutical industry)
• Food processing equipment (soy sauce tanks, salt tanks)
