Metalloy Steel is the leading manufacturer and supplier of the SS 321/321H Flanges. We make these flanges in various shapes and size as per the industrial requirements. In industries, flanges are used in a variety of equipment and thus are required in large quantity. We know the requirement of such industries, and so we make a different kind of flanges as per the necessity.
Flanges we produce follows the set industrial, national and international standards. Alloy 321H is a titanium settled austenitic alloy high in carbon content. This SS 321/321H Flange shows best corrosion resistance property. Also, this alloy is known for oxidation resistance up to 1500 F. In addition to this grade shows low-temperature toughness. Another impressive feature is intergranular corrosion resistance. High creep as well as stress rupture properties property of this grade make it suitable product.
