SS 321H THREADED FLANGES, MANUFACTURER OF ASTM A182 WP321 LAP JOINT FLANGES, READY STOCK OF SS 321 FLANGES, STAINLESS STEEL 321 SORF FLANGES, 321H SS LONG WELD NECK FLANGES SUPPLIER

Hariom Steel is a recognised manufacturer and distributor of SS 321 / 321H Flanges, which has good ductility and weld ability as well as outstanding high temperature characteristics. Due of the outstanding general qualities of this alloy, Stainless Steel UNS S32100 Blind Flanges is employed in a variety of sectors for a variety of various purposes. They are utilized in corrosion-resistant electrical enclosures, wheel covers, automotive molding and trim, culinary equipment, hose clamps, and other applications. Stainless Steel WNR 1.4541 Socket Weld Flanges is required in the most severely carburizing atmospheres of industrial heat treatment furnaces. Preheating is not required for this steel since the inter-pass temperature should not exceed 150° C. This steel is commonly used in exhaust manifolds, bellows, heat exchangers, oil refinery equipment, pulp paper and textile processing equipment, naval equipment, and so on.
