Detailed Information
Dinesh Tube is one of the prominent Supplier & Exporters of ASTM 312 Stainless Steel 321 Welded Pipes. We supply Stainless Steel 321 Pipes in various types like SS 321 Seamless Pipes, SS 321 Welded Pipes, SS 321 ERW Pipes, SS 321 LSAW Pipes, SS 321 Fabricated Pipes. Stainless Steel 321 pipes are made from between 70 % to 90 % recycled materials are fully recyclable at the end of their life cycles. Dinesh Tube’s dedicated teams are always easy to get in touch with, where we are here to support you all the way from materials selection to end use, helping you to get the best result possible from our Stainless Steel 321/ 321H Welded Pipes. SS 321 Seamless Pipe arrives by means of titanium adding together for minimum five times to the content of carbon. SS 321H ERW Pipes can be supplied in cut-to length sizes and also machined or fabricated to meet up your customized piping requirements. Annealing Heat of these 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 intergranular corrosion. The overall characteristics of these Stainless Steel 321H Welded Pipes make it an excellent, relatively low cost choice for many applications.
ASTM A312 TP 321 Stainless Steel Seamless Pipe is a common austenitic 18/8 stainless steel alloy, with the addition of titanium, making it a good choice in high temperature environments of up to 900° C. 321 stainless steel seamless pipe has good welding and forming capabilities and is widely used in operating temperature environments in excess of 500° C. ERW pipes consist of pipes in a size range of 6 inch to 24 inch in all major schedules and thicknesses.
All our Stainless Steel 321 Welded Pipes conform to international standards and are manufactured according to ASTM, ASME, DIN, ANSI, EN, WERKSTOFFE, JIS, BS standards. Dinesh Tubes supplies a full range of specialized Stainless Steel 321 Welded Pipes used for high-performance gas chromatography (GC) and liquid chromatography (LC) as components for chromatography columns used for analytical and preparative processes in diverse industries. Each piece of Pipes is fully tested by professionals according to international standards. Also available at best possible rates in the market.
