Stainless Steel 321 Seamless Pipe


We manufacture Stainless Steel Seamless pipes in ERW, welded, and many other variants as per the requirement occur. The Stainless Steel 321 Seamless Pipe is of SS 321 grade and comes with titanium percentage around 5 times carbon content helping in low carbide precipitation. The SS 321 Welded pipes are welded pipes manufactured with a flat sheet of stainless steel joined with heat the ends. This leaves a joint in the pipes and tubes of welded design. Another variant is 321/321H Stainless steel round pipe manufactured with a composition of 9-12% of Nickel, 17-19% of chromium, Carbon is 0.15% and titanium is 0.80%. The SS 321 ERW tubes hold the same composition but are manufacture by employing the Electric Resistance Welded method (ERW) method. In this process electric current passes through a cold forming strip of stainless steel and then joined with pressure.

The UNS S32100 U tube conforms to the Unified Numbering System (UNS) with U-shaped to meet the specific requirements. Another variant is the UNS S32100 schedule 40 Pipe which conforms to the same standards, however, schedule 40 signifies the wall thickness of 0.154” and 1-inch pipe size.

The ASTM A312 TP 321 ERW pipes conforms to the American Society for Testing and Materials standards. The higher titanium composition leads to lower carbide precipitation and increasing corrosion resistance. Another variant of stainless steel pipe is DIN 1.4541 Rectangular pipe which also comes in square, round, hexagonal shapes, conforms to German Institute of Standardization (DIN) standards with better strength and reliability. The WERKSTOFF NR.1.4541 Heat exchanger Tube is optimum for boiler and other high heat bearing industries with a temperature tolerance of 1600-1650 Fahrenheit. We offer you several ranges of stainless steel pipes according to your specific requirements.
