DC Engineering is a leading manufacturer and supplier of various stainless steel 321 bolts and nuts in various sizes, grades and specifications. The material contains 17% chromium, 9% nickel and titanium for stabilization with carbon, iron, manganese, nitrogen, phosphorus, sulfur and silicon.

Stainless Steel 321 Fasteners Chemical Structure

SS 321 hex bolts have a minimum tensile strength of 621MPa and a minimum yield strength of 276MPa. The material also has a high hardness of 80 HBW. AISI 321 nut bolts are used in high pressure applications due to their high temperature and high melting point. A variety of UNS S32100 321 stainless steel dowel pins have temperatures up to 1399 degrees Celsius depending on the composition. The welding process is better on 321 material than on 304 material due to the addition of titanium. 321 stainless steel threaded rod can be used at temperatures as high as 816 degrees Celsius. Different types of fasteners in this grade like UNS S32100 bolt also have high oxidation resistance and corrosion resistance. Stainless steel 321 bolts are threaded fasteners at both ends designed to secure two components together by engaging the threads of one component with the threads of the other component. The stainless steel 321 bolt alloy used to make them offers exceptional corrosion resistance, high temperature strength and durability, making them an ideal choice for many industrial applications. Stainless steel 321H bolts are made of metal alloys containing at least 10% chromium. This metal contains high levels of chromium and nickel, which gives it excellent corrosion resistance.

Because they contain high levels of chromium and nickel, they can resist corrosion even in damp conditions or when exposed to salt water or other corrosive substances. This makes them ideal for use in marine environments or any other application where corrosion resistance is important. The 321 stainless steel bolt alloy is composed primarily of iron, with a minimum 18% chromium and 8% nickel content. This combination gives it excellent strength and corrosion resistance, making it ideal for use in a wide range of industrial applications. It can withstand temperatures up to 870°C (1600°F), making it suitable for use in high-temperature environments. 321 stainless steel fasteners come with additional titanium in the alloy, increasing its overall physical properties. In other words, adding titanium to Din 1.4449 Bolts helps reduce or prevent carbide precipitation during the welding process.
