Extensively used in the chemical processing industry, plates produced from 904L Stainless Steel have excellent performance especially in the manufacture of phosphate based fertilizers. Whether to improve its corrosion resistance properties or to improve its mechanical properties or to add value to the ASTM A240 904L SS specified sheets, plates, coils or strips, various kinds of finishes could be applied to its surface. Most commonly, the AISI 904L UNS N08904 is finished with Hairline, satin, Embossed, 8K Mirror, brush, matt, PVC film, Hot rolled plate, Cold rolled Plate or laser film finishes.

Apart from the above mentioned finishes, the ASTM A240 Type 904L could be implemented with finishes such as BA, BA NO(8), NO.4, 2B, 2D, NO.8.HL as well as SATIN (Met with Plastic Coated). In comparison to grade 304, the SA 240 Gr 904L SS strips have superior tensile properties. For instance, the yield strength of plates made from 904L is about 490 Mpa, while its shear strength is valued at 73.0 GPa. With a melting point ranging between 2372 – 2534°F, the usual standard thickness the SS Werkstoff No 1.4539 shim stock is produced ranges between 4.8 mm to 50.8mm

What is ASTM A240 Grade 904L Plate?

This specification covers not only the chemical but also mechanical property requirements for a plate, sheet, and strip made from chromium alloy based stainless steel grades such as alloy 904L, which are designed to be used for the construction of pressure vessels and for general applications as well.
