Stainless Steel 321 Pipes are titanium-stabilized austenitic stainless steel pipes that provide exceptional resistance to intergranular corrosion, making them highly suitable for high-temperature service. At Nascent Pipe & Tubes, we manufacture and supply premium-grade Stainless Steel 321 Pipes that meet international quality standards and are designed to perform reliably in corrosive and high-heat environments. These pipes are widely utilized in the petrochemical, aerospace, thermal processing, and chemical industries due to their superior mechanical and physical properties.
Stainless Steel 321, also identified by the UNS S32100 designation, is an alloy that contains titanium as a stabilizing element, which enhances its resistance to chromium carbide precipitation at elevated temperatures. Our ASTM A312 TP321 pipes are specifically engineered for applications involving continuous or frequent temperature ranges between 427°C and 870°C (800°F to 1600°F), where general-purpose stainless steels such as 304 may not suffice. These pipes maintain their strength, structural integrity, and corrosion resistance under high thermal stress, making them ideal for heat exchangers, furnace components, and jet engine parts.
