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.
Due to so many properties of SS 321/321H Flanges, they are mainly used in the aerospace application, storage and equipment in food processing, waste treatment plant, Chemical as well as petrochemical processing. Also, these are used in the gas processing, pharmaceutical, heat exchangers, condensers and pulp-paper industry.
Different types of flanges we produce are spectacle blind flange, SS socket weld flange, SS weld neck flange and SS ring joint flange. We also customise the SS 321/321H flanges in custom specifications. All the material we use are tested and impurity free. Product is individually tested and inspected by the inspection team. The product documentation, test certification and packaging are done.
