Contact SupplierRandhir Metal is a well-known firm that manufactures and supplies a wide range of SS 321 / 321H Nipple, which cannot be hardened by thermal treatment. Stainless Steel 321 Nipple is stabilized against chromium carbide formation by the addition of titanium. However, welded Stainless Steel 321H Nipple must never be used in highly oxidising environments as it is liable to ‘Knife-line’ attack. Characterized by high corrosion resistance in general atmospheric corrosive environments, SS 321 Hexagon Reducing Nipple exhibits excellent resistance to most oxidizing agents. This heat resistant grade of SS 321H Hexagon Nipple has a maximum dry air service temperature of 850 º C. Like other austenitic stainless steels, Alloy 321 One End Threaded Nipple works harden quickly and may require annealing after severe forming. Alloy 321H Both End Threaded Nipple is stabilized against weld heat affected zone (HAZ) inter-granular corrosion.
