About 321 Stainless Steel

Stainless Steel 321 is the stabilized version of Stainless Steel 304. The 18/8 blend of chromium and nickel is tempered with titanium to give type 321 protection from intergranular corrosion that can occur after heat treatment. It is protected from temperatures ranging from 800 to 1500° F. The metal displays high strength and resistance to various forms of corrosions, including that from aqueous environments. Type 321 finds application in heavy welding components, along with dynamic environments that are subject to changes.

However, the addition of titanium limits the application of 321 in terms of working. The metal is not recommended for certain welding techniques as it is not consumable. Beyond this, stainless steel 321 has excellent forming characteristics, does not require annealing after being welded, and displays toughness in a range of temperatures. The metal shows strength even when exposed to cryogenic temperatures. Additionally, it is often chosen over Type 304 for its increased resistance to creep and rupture. Both metals may be susceptible to stress corrosion cracking.

Stainless Steel 321 is a basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) addition. SS 321 is used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Stainless Steel 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. SS 321H is a modification of SS 321 with a higher carbon content, to provide improved high temperature strength.

Value Added Services for Stainless Steel Plates

  • Packing – We can place stainless steel plates as per your requirements. Normally we have stainless steel plates packed on wooden pallets. On special requests from our customers, we can also do custom packing especially for our export customers.
  • Plasma Cutting – Metline has in-house plasma cutting facilities. We can cut the plates to suit your size requirements, through plasma or fire cutting.
  • Water Jet Cutting – For special size stainless steel plates, we can also offer water jet cutting. However, the cost is higher for water jest cutting as compared to plasma cutting.
  • Laser Cutting – Laser cutting is the most expensive, and required for precision engineered parts. Stainless steel plates can be invoiced separately, and we can separately charge for laser cutting, if the customer accepts the same.
  • Custom Machining – We have in-house machining facilities, and can process stainless steel blocks as per your drawings. If you a are looking for precision engineered stainless steel blocks, please do contact us.
  • Various Forms – We can offer flat rolled products in various forms such as Coils, Foils, Rolls, Plain Sheet, Shim Sheet, Perforated Sheet, Chequered Plate, Strip, Flats, Blank (Circle), Ring (Flange) etc.

Test Certificates & Documentation

  • All Products are Supplied with Mill Test Reports, as per EN 10204 3.1
  • Supplementary Tests Can be Carried Out – Hardness Test, Chemical Analysis – Spectro Analysis, Positive Material Identification – PMI Testing, Flattening Test, Micro and MacroTest, Pitting Resistance Test, Flaring Test, Intergranular Corrosion (IGC) Test
  • Documents – Complete set of documents are provided along with supplies of goods, such as Invoice, Packing List, Test Reports, Certificate of Origin, Insurance Copy, Heat Treatment Charts. We also send pictures of all materials, before delivery to all our customers to take their approval.
