Mahavir Metals India is a well-known supplier and manufacturer of SS 321 Pipe Fittings, where our experts ensure suitable delivery of both large and small orders in order to maintain the highest level of quality. The resistance to sensitisation of 321 Stainless Steel Butt Weld Pipe Fittings, combined with its greater potency at high temperatures, makes it ideal for applications where Alloy 304 will become sensitized or where Alloy 304L has insufficient hot potency. Alloy 321 Pipe Fittings are similar to SS 304, except they have a Titanium concentration that is at least 5 times that of SS 304. This build-up is designed to reduce or eliminate chromium carbide precipitation caused by high-temperature exposure or welding. Butt Weld Fittings in Stainless Steel 321 are a stabilized austenitic alloy, similar to Stainless Steel 304, but with a titanium accumulation of at least five times the carbon content.
SS 321Butt Weld Fittings (DIN 1.4541) is a stabilized alloy with a high resistance to intergranular corrosion when exposed to temperatures in the chromium carbide precipitation range of 427 to 816 degrees Celsius. We sell Grade 321 Stainless Steel Pipe Fittings at a low price. Stainless Steel 321 Butt Weld Pipe Fittings (UNS S32100) is an excellent quality for functions in the temperature range of up to roughly 900 degrees Celsius, combining high potency, phase stability, and scaling resistance through resistance to subsequent aqueous corrosion.
