Shashank Stainless is one of the top manufacturers and suppliers of Stainless Steel 321 Bolts in Dubai, United Arab Emirates. Our Stainless Steel 321 Bolts are made from the best Stainless Steel 321 material that has outstanding resistance to oxidation and corrosion at high temperatures. This grade is excellent for welding and therefore our bolts are ideal for use in heat exchangers, boilers and other industrial applications. We are committed to delivering superior quality in all our products, with strict standards for performance and durability.
Stainless Steel 321 Bolts provide outstanding oxidation and corrosion resistance especially at temperatures up to 1500°F (815°C). They have excellent weldability and mechanical properties providing strength and durability in harsh environments. The addition of titanium enhances the resistance to intergranular corrosion making these bolts suitable for high stress applications. Their resistance to sulfur compounds and other corrosive agents makes them reliable in industries such as aerospace, chemical processing and petrochemicals. They also provide good performance under thermal cycling conditions.
