GNEE stocks 904l stainless steel plate sheets in thicknesses from 3/16" through 2". Alloy 904L (UNS N08904) is a superaustenitic 904l stainless steel plate sheets designed for corrosion and pitting resistance in a wide range of process environments. 904l stainless steel plate sheets is used extensively in the chemical process industry including the production of phosphate-based fertilizers.
Available thicknesses for 904l stainless steel plate sheets:
| 3/16" | 1/4" | 3/8" | 1/2" | 5/8" | 3/4" |
|---|---|---|---|---|---|
| 4.8mm | 6.3mm | 9.5mm | 12.7mm | 15.9mm | 19mm |
| 1" | 1 1/4" | 1 1/2" | 1 3/4" | 2" | |
| 25.4mm | 31.8mm | 38.1mm | 44.5mm | 50.8mm |
904l stainless steel plate sheets was originally developed to withstand environments containing dilute sulfuric acid.
904l stainless steel plate sheets is easily welded and processed by standard shop fabrication practices.
Conventional stainless steels such as 304L and 316L are susceptible to chloride stress corrosion cracking (SSC) under certain conditions. Resistance to SSC increases with the increased content of nickel and molybdenum. Therefore, the higher performance austenitic stainless steels such as 904L have very good resistance to SSC. The table in the upper right corner shows resistance to SSC in a chloride solution under evaporative conditions. High performance austenitic steels and duplex stainless steels clearly outperform 316L.
