    Product Description

    Prime Quality Stainless Steel Sheet Price 904L

    Grades 904L is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance..It is is easily welded and processed by standard shop fabrication practices.
    With its highly alloyed chemistry — 25% nickel and 4.5% molybdenum, 904L provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance superior to 316L and 317L molybdenum enhanced stainless steels.
    Alloy 904L was originally developed to withstand environments containing dilute sulfuric acid. It also offers good resistance to other inorganic acids such as hot phosphoric acid as well as most organic acids.

    Possible Alternative Grades

    The suitable alternatives to 904L stainless steels are tabulated below:

    Possible alternative grades to grade 904L stainless steels

    GradeReasons for choosing grade 904L
    316LA lower cost alternative, but with much lower corrosion resistance.
    6MoA higher resistance to pitting and crevice corrosion is needed.
    2205A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.)
    Super duplexHigher corrosion resistance is needed, together with a higher strength than 904L.

    Fabrication

    Grade 904L stainless steels are high purity steels with low sulphur content. They can be machined using any standard methods. These grades can be readily bent to a small radius under cold conditions. Although subsequent annealing is not required in most cases, it should be carried out when the fabrication is performed under severe stress corrosion cracking conditions.

    Applications

    Some of the major applications of grade 904L stainless steels include:

    • Wiring in electrostatic precipitators

    • Oil refinery components

    • Seawater cooling devices

    • Gas scrubbing plants

    • Pulp and paper processing industries

    • Acetic, phosphoric and sulphuric acid processing plants
