Product Details

SS321 Nut
The nut is a fastener with internal threads and used in conjunction with a screw for mechanical parts for movement or power.

BDF can offer all kinds of hot forged and cold formed nuts such as hexagon nuts, heavy hex nuts, hexagon coupling nuts, hexagon thin nuts, hexagon castle nuts, self locking nuts, hexagon domed cap nuts and other non-standard nuts according to customer drawings. The size ranges from M6-M100 in METRIC and 3/8” to 3-1/2” in INCH.
321 alloy has the following characteristics: 1, where Ti exists as a stabilizing element, but it is also a hot steel type, in the high temperature than 316L is much better. 2, in different concentrations, different temperatures of organic acids and inorganic acids, especially in the oxidizing medium has good wear resistance, for the manufacture of wear-resistant acid containers and wear-resistant equipment lining, pipeline. 3, is Ni-Cr-Ti austenitic stainless steel, its performance and 304 is very similar, but due to the addition of metal titanium, it has a better resistance to grain boundary corrosion and high temperature strength. Due to the addition of metal titanium, so that the effective control of the formation of chromium carbide. 4, with excellent high temperature stress breaking (StressRupture) performance and high temperature creep resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel.
