RANDHIR STAINLESS STEEL 321 SCREW, Certification : ISI Certified

Randhir Metal is a well-known firm that manufactures and distributes a wide range of SS 321 / 321H Screws, which is an electric-furnace processed austenitic stainless steel. These Stainless Steel 321 Screws is a titanium-stabilised version and used in particular applications within the sensitizing temperature range. This titanium addition in Stainless Steel 321H Screws reduces or prevents carbide precipitation during welding and in the 800 ° – 1500 ° F service conditions. However local depletion within the weld area of Stainless Steel 321 Hex Head Screws can still be a problem leading to some inter-granular corrosion if later exposed to severe corrosive conditions. The key property of Stainless Steel 321H Socket Head Cap Screws is the added titanium content stabilising the material and making its resistance to carbide precipitation when exposed to high temperatures and resistance to oxidation its main characteristics. Resistance to organic acids and some inorganic acids in Stainless Steel 321 Socket Set Screws is excellent. Stabilization in Stainless Steel 321H Anchore Screws is recommended for most severe service conditions (above 425 ° C) and particularly for material annealed at the upper side of the annealing temperature range. Stainless Steel 321 Blind Rivet Screws has excellent resistance oxidation to 1500 ° F (816 ° C) and good low temperature toughness. Stainless Steel 321H Concrete Screws has working temperatures of 2100 – 2300 ° F (1149 – 1260 ° C) are recommended for forging, upsetting and other hot working processes.
