Stainless Steel 321 Pipe Fittings

Stainless Steel alloy 321, or as also referred to as UNS S32100 is the titanium stabilized version of Stainless Steel grade 304. The 18/8  alloy blend of elements chromium and nickel have been tempered with titanium in order to impart protective characteristics to stainless steel grade 321 from getting decayed by intergranular corrosion which can occur after the performance of heat treatment on the alloy. The ASTM A403 WP321 Pipe Fittings has the ability to withstand elevated temperatures ranging from 800 to 1500° F. The alloy exhibits high tensile strength and resistance to various forms of corrosions. This includes resistance against aqueous environments as well. Therefore, Stainless Steel 321 Pipe Fittings find application in heavy welding components, in addition to dynamic environments that are subject to frequent changes like in process based industries.

However, the addition of titanium to its alloy limits the application of 321 in terms of working. The alloy for A403 WP321 Elbow is not recommended by many manufacturers for certain welding techniques as it is not consumable. This aside, stainless steel 321 has excellent forming characteristics. Hence, the alloy does not require annealing after the SS 321 Pipe Fittings has been welded. Moreover, these fittings display toughness across a wide range of temperatures. This particular stainless steel grade demonstrates good tensile strength even when the fittings have been exposed to cryogenic temperatures. Additionally, fittings such as the UNS S32100 Tee are often chosen over grade 304 for the alloys increased resistance to creep and rupture. However, both grade 304 as well as stainless steel alloy 321 tend to be susceptible to stress related corrosion cracking.
