Stainless Steel F321/F321h Flanges

Stainless Steel F321/F321h Flanges  are the Standard Specification for Forged Stainless Steel Pipe Flanges and Stainless Steel Forged Fittings. Included are flanges, fittings and similar parts to specified dimensions or to dimensional standards, such as ASME requirements.

F321/F321h stainless steel flanges are austenitic stainless steel plates with titanium stabilisation. As a result of exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C), it has excellent resistance to intergranular corrosion. Alloy 316L resists oxidation up to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. Additionally, it is tough at low temperatures.

The stainless steel F321/F321h flanges have a higher carbon content (0.04 – 0.010). This material was developed to enhance creep resistance and strength at temperatures above 1000°F (537°C). The carbon content of the plate allows dual certification in most cases. ASTM A182 F321 Flanges are widely used in industrial, architectural, and transportation applications.

Our company is widely recognized as a leading manufacturer, exporter, and supplier of Stainless Steel F321/F321h Flanges. Flanges manufactured in accordance with ASTM A182 F321 standards are designed with utmost precision.
