ASTM TP904L Seamless Stainless Steel Tube Sch40 Used In Excellent Mechanical Properties
904L stainless steel plate is a special stainless steel material with high corrosion resistance, mainly composed of chromium, nickel, molybdenum and other elements. It gets its name because it contains up to 23% nickel and low carbon content (C≤0.02), which provides excellent corrosion resistance.
904L stainless steel is based on 316L stainless steel with some changes. In terms of composition, 904L stainless steel has 1.6 times more chromium, nickel and molybdenum content than 316L stainless steel, and 904L stainless steel has more copper components. Therefore, 904L stainless steel is more wear-resistant, more corrosion resistant, and heavier. But there's not much difference in hardness. Designed for harsh corrosion conditions, the alloy was originally developed to resist corrosion in dilute sulfuric acid.
Applications:
904L stainless steel plate is often used in chemical, petroleum, pharmaceutical, Marine engineering, food processing and other fields. It is often used to make chemical reactors, storage tanks, coolers, furnace tubes, offshore drilling platforms and other equipment and components requiring high corrosion resistance and excellent mechanical properties.
