Stainless Steel 321 / 321H Welded Tube Manufacturer

Supplier & Exporter of Stainless Steel 321/321H Welded Tubes

SS 321 and SS 321H Welded Tubing is a type of Welded stainless steel. SS 321 / 321H Welded Tubes is a standard austenitic chromium-nickel alloy with the addition of Titanium making it an excellent choice in elevated temperature environments. It is stabilized by the addition of titanium. Titanium does not allow the formation of chromium carbide in it. If the industrial product is made using this alloy then it adds several features to the product like amazing resistance against intergranular corrosion, and also provides resistance against high temperature. 

Moreover, it also provides it with higher stress rupture properties and higher creep properties. This alloy contains a higher percentage of carbon in comparison to other alloys. Also, alloy could be used for absolute phosphoric acid at a low-temperature range and diluted acids at high temperatures. This material is the best choice because it can be used for a temperature up to 900 degrees Celsius. ASTM A269 TP SS 321 Welded Tubes has good corrosion resistance that is quite alike to SS 302 or SS 304 in the annealed form and also higher if a weldment has not been post-weld annealed or if the application engages service in the range of 800 Deg F to 1600 Deg F.

SS 321 Welded Tubing is preferred in many companies and industries which includes paper and pulp industries, petrochemical industries, chemical industries, water processing industries, oil refineries, gas-related industries, food processing industries, dairy industries, marine industries, onshore and offshore industries, and many more. Our Stainless Steel 321 Welded Tubes are tested and examined by industrial experts to ensure high standard quality, creek, or damages before supplying them to our clients. We perform a number of tests on our SS 321H Welded Tube to ensure high standard quality. The tests conducted Pitting Resistance Test, PMI Testing, IGC test, Chemical Test, Mechanical Test, Hardness Test, Flattening Test, Flaring Test, Micro Test & Macro Test, Tensile Test, etc. Some of the other tests are chemical analysis, eddy current testing, hydrostatic testing or ultrasonic examination, NDT, and also chemical and physical property inspection, Rockwell hardness test, chemical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection, and so on.

We offer various types of SS 347 / 347H Welded Tubing such as Round Tubes, Heat Exchanger Tubes, Hydraulic Tubes, Coiled Tubes, Cold Drawn Tubes, Seamless Tubes, Square Tubes, Rectangular Tubes, Decorative Tubes, Sanitary Tubes, Polish Tubes, Instrumentation Tubes, Bright Annealing Tubes, and many more. SS 321H Welded Tubing both are made of austenitic stainless steel. They possess several benefits, where the first one is resistance to higher temperatures, excellent intergranular corrosion resistance has low-temperature toughness, resists oxidation at higher temperatures. Our Stainless Steel 321 Round Tubes are often used in woven or welded screens for high-temperature mineral processing. These Stainless Steel 321H Square Tubes are extremely resistant to inter-granular corrosion and have very good corrosion resistance in weld areas. Our Stainless Steel 321 Rectangular Tubes are also used in waste treatment including thermal oxidizers. The hardening rate of these Stainless Steel 321H Electropolish Tubes makes it less machinable than 410 stainless steel, but similar to Alloy 304.
