Application of different types of 321 stainless steel hex nuts
The substance 321 is austenitic stainless steel that is very stable. 17% chromium, 9% nickel, and titanium are included in the material, along with carbon, iron, manganese, nitrogen, phosphorus, sulfur, and silicon. These elements serve to stabilize the substance.
Hex bolts made from SS 321 have a minimum tensile strength of 621 MPa, while their minimum yield strength is 276 MPa. Moreover, the material has a high hardness rating of 80 HBW. Because of their high melting point, AISI 321 nut bolts are frequently utilized in settings with high temperatures and pressures. Dowel pins made of stainless steel with a UNS S32100 321 designation can withstand temperatures of up to 1399 degrees Celsius, depending on the composition of the material. Due to the presence of titanium in material 321, the welding process produces superior results to material 304. A temperature of 816 degrees Celsius is the maximum temperature at which a threaded rod made of 321 stainless steel can be utilized. Some types of fasteners of this grade, such as SS 321 screws, have high oxidation resistance in addition to their resistance to corrosion.
