Stainless Steel Plates - Jindal Stainless


Plates are manufactured through continuous casting & subsequent hot rolling of slabs after annealing and pickling, or by cutting hot rolled annealed pickled coils to desired lengths.


Plates can be available in thicknesses ranging from 6mm to 80mm, in the following austenitic, ferritic, duplex, and martensitic grades:

  • Austenitic Grades: They possess an austenite phase (which has a face-centered cubic, FCC crystal structure). FCC crystal structure gives the required ductility & toughness for these grades. This can be achieved by alloying steel having more than 16% chromium with sufficient nickel and/or manganese and nitrogen to maintain an austenitic microstructure at all temperatures, ranging from room temperature to its melting point.
  • Ferritic Grades: They possess a ferrite phase (which has a body-centered cubic, BCC crystal structure). Ferritic stainless steels contain between 10.5% and 27% chromium with very little or no nickel. This ferrite microstructure is present at all temperatures due to the chromium addition, so they are not hardenable by heat treatment. They cannot be strengthened by cold work to the same degree as austenitic stainless steel. But they are magnetic, unlike Austenitic grades.
  • Martensitic Grades: Martensitic structure (which has a body-centered tetragonal, BCT crystal structure) is formed when a high-temperature austenite phase is rapidly quenched to room temperature. Martensitic stainless steels offer a wide range of properties and are used as stainless engineering steels, stainless tool steels, and creep-resistant steels. They are magnetic, and less corrosion-resistant than ferritic and austenitic stainless steels due to their lower chromium content. Martensitic grade plates are supplied in the annealed condition.
  • Duplex Grades: They contain a mixed microstructure of austenite and ferrite (usually a 50:50 ratio). They can offer higher yield strength compared to austenitic stainless steel, good corrosion resistance & good stress-corrosion cracking resistance.


Hot-rolled plates are further annealed to obtain good mechanical properties like toughness & ductility.

Plates with No. 1 finish as per ASTM A480/A480M can be produced after shot blasting (Mechanical removal of surface oxide layer) & pickling (oxide layer is removed by chemical reaction).

Applications of Plates:

Due to the excellent ease of manufacturability, plates are used in tanks, pressure vessels, structural applications, etc.

It also offers excellent corrosion resistance properties.
