Ninthore Overseas is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 321 Pipes, which is often used in spiral Welded tube for burner pipes and flues. Our Stainless Steel 321 Pipes can be slit to your desired width, where annealing is required to rectify if necessary. Annealing Heat of these Stainless Steel 321H Pipes to 1750 ° F – 2050 ° F (954 ° C – 1121 ° C), then water quench or air cool. Our Stainless Steel 321 Seamless Pipes can be stress-relief annealed within the sensitization temperature range 450 Deg C – 800 Deg C without carbide precipitation occurring, thus avoiding the possibility of inter-granular corrosion.

Stainless Steel 321 Pipes

The overall characteristics of these Stainless Steel 321H Welded Pipes make it an excellent, relatively low cost choice for many applications. Our Stainless Steel 321 EFW Pipes is generally considered to have comparable weldability to Stainless Steel 304 and Stainless Steel 304L with the main difference being the titanium addition which reduces or prevents carbide precipitation during welding.

These Stainless Steel 321H ERW Pipes has extensive use in aircraft parts, such as exhaust systems where operating temperatures are higher than 800 ° F. Our Stainless Steel 321 Round Pipes has slightly less corrosion resistance to atmospheric conditions than Alloy 302 or Alloy 304 in the annealed condition. These Stainless Steel 321H Square Pipes has equipment and storage units for Food processing and Aerospace applications.
