A312 TP321 Seamless Pipe often referred to as a marine grade stainless steel because of its effective resistance to chloride corrosion in comparison to other grades. It is an austenitic grade pipe with the addition of 2-3% molybdenum which further improves corrosion resistance. In this standard also has TP321H, which has high carbon content that for better high temperature creep property. Both TP321 and TP321H have lower strength requirements for pipe manufactured in nominal wall thicknesses greater than 3/8 in. [9.5 mm].

 

SS321 pipes have a good performance in high temperature, corrosive environment, and it also has excellent weldability. So they are very popular and available in wide range of industries.

 
Product Analysis

At the request of the purchaser, an analysis of one billet or one length of flat-rolled stock from each heat, or two pipes from each lot shall be made by the manufacturer. A lot of pipe shall consist of the following number of lengths of the same size and wall thickness from any one heat of steel:

Hydrostatic or Nondestructive Electric Test

Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

 

For pipe whose dimensions equal or exceed NPS 10, the purchaser, with the agreement of the manufacturer, may waive the hydrostatic test requirement when in lieu of such test the purchaser performs a system test. Each length of pipe furnished without the completed manufacturer’s hydrostatic test shall include with the mandatory markings the letters “NH.”

Nondestructive Electric Test:

Nondestructive electric tests shall be in accordance with Specification A 999/A 999M.

 

The grade 321 steel can be made into plates, sheets, and coils to be used in the following:

  • Food preparation equipment particularly in chloride environments.
  • Laboratory benches & equipment.
  • Coastal architectural panelling, railings & trim.
  • Boat fittings.
  • Chemical containers, including for transport.
  • Heat exchangers.
  • Woven or welded screens for mining, quarrying & water filtration.
  • Threaded fasteners.
  • Springs.
