Introduction About 904L Stainless Steel Plate


904L Stainless Steel Plate is a rectangular shaped hot rolled treated plate made of stainless steel material and is available in various sizes and thickness that varies from 1mm to 5 mm or goes upto 80 mm or more.
Moreover, this type of plate is widely demanded for its efficiency, high performance, rigid design, easy operations, rust proof body and shock proof nature. It is firstly used by a Rolex wristwatch manufacturer in its watches because of its ultimate properties and features.

Properties:-
  • Mechanical properties – Tensile strength, Elongation, Yield strength, Hardness
  • Physical properties – High density, Elastic modulus, Thermal conductivity, Electricity resistant
  • Non magnetic, Austenitic type of steel, Prevents inter-granular corrosion
Applications:-

904L Stainless Steel is highly used for wiring in electrostatic precipitators, oil refinery components, sea water cooling devices, gas scrubbing plants, pulp and paper processing industries, acetic, phosphoric, and suphuric acid processing plants.

Surface Finishes for Stainless Steel Plates are as follows:-
  • Scotch Brite (very fine hairline finish)
  • Embossed (cold rolled annealed and pickled)
  • Anti- Fingerprint (coated with acrylic solution)
  • No.8 / Mirror (polished to mirror finish)
  • Etching (pattern surface)
  • 2E (mechanically descaled and pickled)
Some other applications where 904L Stainless Steel Plate are used:-
  • Food processing and handling
  • Heat exchangers
  • Chemical process vessels
  • Conveyors
  • Architectural
  • Piping systems
  • Pollution control equipment
  • Heat exchangers
  • Bleaching systems
Following are the brilliant features of 904L Stainless Steel Plates:-
Durability – 904L Stainless Steel is used for making storage tanks to paper machines in order to achieve significant thickness reductions and cost savings across application lifetimes.

Corrosion resistant – 904L Stainless Steel has high chromium and nickel content, coupled with additions of molybdenum and copper, assure from moderate to high corrosion resistance.

Harsh environmental friendly – 904L Stainless Steel is 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.

Heat resistant - 904L Stainless Steel can be solution heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for hardening these grades.

Grade 904L is non-magnetic, and offers excellent form ability, toughness and weld ability.
