Adinox Overseas is a major manufacturer and an exporter of top quality Stainless Steel 321 Fasteners which satisfy extravagant industrial premises. These are titanium-stabilized austenitic stainless steel fasteners, that have high resistance to intergranular corrosion and possess high capability of high-temperature usage. Stainless Steel 321 with the UNS S32100 and ASTM A193 Grade B8T is a material that is perfectly suitable in situations that require exposure at high temperatures extending into the 900-1500 o F (480-800 o C ) range.

Our SS 321 Fasteners find extensive applications in thermal processing equipment, in the heat exchangers, exhaust manifolds, expansion joints and aerospace applications rated at high temperature, where high temperature stability and resistance to stress rupture is critical. By alloying titanium (at least five times as much carbon) Stainless Steel 321 provides greater resistance to precipitation of chromium carbide upon welding and exposure to elevated temperatures, and is a suitable choice as a structural material in welded conditions.

Our UNS S32100 fasteners have high oxidation resistance to 870 o C. They are scale-resistant, too, and display structural characteristics under conditions of extreme thermal fatigue. In contrast with other grades, 321 stainless steel cannot be hardened by a heating process but can be strengthened by cold working. This property renders our fasteners suitable in the parts that have to undergo recurrent heating and in the medium corrosive surroundings.
