The specification for A403 WP321 material covers Austenitic Stainless Steel grade Pipe Fittings. Typically, these 321 Pipe Fittings used in industries or sectors such as engineering, energy conversion plants, etc. According to the specification ASTM A403 SS 321 Fitting can be manufactured in seamless and welded type. Operations like Forging or shaping must be performed  on the A403 WP321 fittings by either one or a combination of two or more of these operations  like - hammering, piercing, pressing, extruding, upsetting, rolling, bending, fusion welding, machining. All fittings made from the A403 WP321 material must undergo heat treatment. 


Dimensions of the ASTM A403 WP321H Fittings include - ASME/ANSI B16.9, ASME B16.28, MSS-SP-43. While the size of the 321 Stainless Steel Fittings ranges from 1/8 inch NB to 48 inches NB.

The Alloy for ASTM A403 WP321 Material is stabilized stainless steel fitting. The main reason for the A403 WP321H material being popular is because of its excellent resistance to intergranular corrosion even on prolonged exposure to temperatures. This holds true for the 321H Pipe Fittings, which in the chromium carbide  temperature precipitation range ( i.e. from 800 °F to 1500 °F ) remains stable. A403 Grade WP321 Buttweld Fittings are stabilized against chromium carbide formation by the addition of titanium to the alloy during its manufacture.

At high temperatures, ASTM A403 gr WP321 fittings prove to be advantageous for service because of their good mechanical properties and their good performance when exposed to these temperatures. One such advantage offered by the ASTM A403 WP321 Fittings is their higher creep and stress rupture properties, which are much better as compared to stainless steel grades 304 as well as Alloy 304L. Which could also be considered for applications where these A403 WP321 Elbow fittings are exposed to environments where  sensitization and intergranular corrosion are primary concerns of these applications.

321H SS Weld Fittings are basically the same as the regular 321 grade stainless steel, the only difference between them is the content of carbon. In the SS 321H Fitting, the content of carbon is higher i.e. -  between 0.04% to 0.10% of the alloy. The reason for developing these 321H Stainless Steel Fittings was to enhance their creep resistance as well as for their higher tensile strength, especially at temperatures above 537°C.

Although the A403 Grade WP321H Buttweld Fittings And ASTM A403 WP321 Material can’t be hardened by heat treatment, these fittings can be hardened only through cold working.  A benefit of using these A403 WP321  fittings is that can be easily processed  & welded by standard shop fabrication techniques.
