    Detailed Information

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

    Newzel is a well-known manufacturer, stockist & supplier of ASTM A312 Stainless Steel 321/321H Welded Pipes. Our ranges of ASTM A312 TP 321/321H SS pipes have complied with several national and international product quality standards. SS321 is a titanium-based austenitic SS with very good resistance to general corrosion. These pipes are chromium-nickel alloy with the addition of titanium which makes it excellent in elevated temperature environments. The SS 321H Welded Pipes also show the equivalent properties are the SS 321 Welded Pipes. It is having phenomenal resistance ability against corrosion into the carbide precipitation temperature ranges from 427 to 816 deg C. It also maintains oxidation to temperature 816 deg C. Furthermore, it has stress and creep-rupture properties. SS321H is the modification of SS321. This material is developed for improvising creep resistance and also greater strength at a temperature ranging 537 deg C.

    These SS 321 Welded Pipes are used in the petroleum industry, chemical industry, making the superheater of the boiler and also in the making of the heat exchangers. As these pipes are high-temperature resistance then they are used in the transmission of the fluid in the power station. It is also used in exhaust purification devices, for construction purposes. And the SS 321H Welded Pipes are used in the oil refinery types of equipment, industrial boilers, in making the pressure vessels, and in many chemical processes in the heat exchangers. Our Stainless Steel 321 EFW Pipes is for the most part considered to have tantamount weldability to Stainless Steel 304 and Stainless Steel 304L with the primary distinction being the titanium expansion which lessens or forestalls carbide precipitation during welding.

    Type 321 is mainly used in applications that require heating between 800-1650 Fahrenheit. 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 Welded 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. These pipes are also used in the industries of petrochemical, natural gas, papermaking, and much water processing, etc. It can transport liquids that have a high temperature and also the gases of high pressure. These pipes have the feature of high tolerance and dimensional stability. These Stainless Steel 321H ERW Pipes have 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.

    The packaging is done in wooden boxes, bundled, wooden crates to protect the package from unauthorized access. Before supplying these Stainless Steel 321 Welded Pipes to our clients, they are tested in terms of quality by our quality controllers such as flaring test, flattening test, positive material test, third-party inspection test, chemical test, intergranular test, Rockwell hardness test, and mechanical test. Because of the wide scope of widths and thicknesses and the assortment of tempers delivered in our ASTM A312 Stainless Steel 321H Welded Pipes and cut lengths, no levelness resiliences have been set up for cold moved hardened steel. Evenness on temper abounded in these Stainless Steel S32100 / S32109 Welded Pipes can’t be ensured. These Stainless Steel 321/321H Welded Pipes are a universally useful grade often supplied in the solidified, yet machinable condition, for applications where high strength and moderate warmth and erosion obstruction are required.
