Stainless Steel 321/321H Pipe Fittings

Micron Steel is a well-known manufacturer, traders, supplier and exporter of a range of Stainless Steel 321 / 321H Pipe Fittings. Alloy 321 is a Titanium stabilized Austenitic steel which bears a good general corrosion resistance. It executes excellent resistance to intergranular corrosion after exposure to chromium carbide precipitation range at temperatures of 800–1500°F. Apart from this the alloy also resists oxidation at 1500°F. It shows a high range of creep and stress rupture properties than 304/304L Alloys. Alloy 321 contains high carbon content and was developed to provide enhanced creep resistance.

It also shows higher strength at temperatures above 1000°F. Heat treatment cannot harden Alloy 321. Our SS UNS S32100 Pipe Elbow find application in Chemical Processing, Expansion Joints and more. Aerospace Industry also uses these SS WNR 1.4541 / WNR 1.4878 Butt Weld Reducer as piston manifolds usage. We offer products of the highest quality to our customers.
