Siliconsteel manufactures and sells a number of various grades of flanges. One of the Flanges forms on our inventory is SS 321 Flanges. Each flange has its characteristics and qualities. We produce all types of flanges with various specifications, taking into account all industry requirements, and contributing to their production.
Alloy 321 consists of Chrome-Nickel Stainless Steel with Austenitic Titanium. This classification offers intergranular resistance to corrosion, in particular. Alloy 321 is acceptable for applications involving welding at high temperatures. The Alloy 321 contains 0.08% carbon, 0.75% silicon, 0.10% nitrogen and 2% manganese. Alloy 321H is a higher 321 Carbon variant, offering several advantages. Alloy 321H offers high toughness at low temperatures, excellent oxidation resistance, very ductile, and fast shapes. All of these characteristics and qualities are ideal for the development of flanges.
Our SS 321 Flanges offers corrosion resistance, reliability, rust-free, oxidation-resistant, and high solderability. Such advantageous flanges are ideally suited for various industries, including petrochemical, pulp, and paper manufacturing, chemical, pharmaceutical, aerospace, food processing, coal, and power plant industries.
We can manufacture SS 321 flanges in the new technologies and modern equipment. SS 321 Flanges are planned and produced in compliance with national and international standards. Our team of qualified experts tracks flanges output to ensure smooth surface finishes and smooth dimensional precision. We give our customers better Flanges anticipated by the use of sophisticated technology and modern tools. We produce SS 321 Flanges in bulk without compromising their consistency with the use of technology.
