ASTM A403 WP321 Pipe Fittings Specification

Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings


ASTM A403 WP321 covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations. All fittings shall undergo heat-treatment.

Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, and titanium. Tension test shall be done on the fitting material to determine the tensile properties such as yield strength and tensile strength. Fittings supplied under this specification shall be examined visually for surface discontinuities, surface checks, and mechanical marks.

  • A butt weld Pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.
  • This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.
  • Other types of fittings can be threaded or socket welded.

Several grades of austenitic stainless steel alloys are included in this specification. Grades are designated with a prefix, based on the applicable ASTM/ASME or MSS standards. For each of the WP stainless grades, several classes of fittings are specified, to indicate whether seamless or welded construction was utilized. Class designations are also utilized to indicate the nondestructive test method and extent of nondestructive examination. A general summary of the fitting classes applicable to all WP grades of stainless steel follows. There are no classes for the CR grades

Fitting Classes for WP Grades

CR Corrosion resistant grade. S through WU Classes do not apply.
WP-S Seamless
WP-W Welded, RT or UT all pipe starting material welds made with filler metal. All fitting manufacturer welds except as excluded in A/SA403 paragraph 5.4.3.
If UT is substituted for RT, all welds must be examined 100% for their length as required by A/SA403 paragraph 5.6
WP-WX RT all welds with or without filler metal.
WP-WU UT all welds with or without filler metal.
WPgrade-grade-class Insert grades (304-304L) and class (S,W,WX, or WU). Applies to fittings meeting all chemical and physical requirements of both grades.

UNS S32100 / UNS S32109

ASTM A403 WP321 is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800–1500°F (427–816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.

ASTM A403 WP321H is the higher carbon (0.04–0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification. Alloy 321 cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.

Power plants using fossil or nuclear fuels. Geothermal energy for harnessing heat from the earth.
  • Food and beverage production. From basic ingredients to elaborate desserts. From milk, to juices and other beverages. Cold chain to keep produce fresh, drinks and frozen foods at a set temperature. Desalination plants to transform seawater into drinking water for arid areas and various tropical islands.
  • Pharmaceuticals and biotech production. Medicines and vaccines that treat illnesses and help restore bodies and minds to their top conditions.
  • Semiconductor manufacturing: Microchips that go into all electronics, including smartphones, tablets, computers, television sets, telecom networks, …
  • Pulp and paper production. Newsprint, glossy paper, cardboard boxes, books, writing paper, …
  • Production of construction materials and plastics. From roofing materials, to glassmaking for windows, to copper wiring for transporting electricity, and various plastics throughout houses and office buildings.
