Astec Tubes are prominent manufacturers, supplier and exporters of high quality Stainless Steel 321/321H Pipe in Mumbai, India. These SS 321/ 321H Pipes are manufactured using high quality raw materials and latest technology in various types such as seamless, welded, erw, etc. Stainless Steel 321 Pipes is titanium settled austenitic stainless steel with greater general corrosion resistance. It has phenomenal resistance to intergranular corrosion after presentation to temperatures in the chromium carbide precipitation scope of 800–1500 degrees F (427–816 degrees C).The alloy maintains oxidation to 1500 degrees F (816 degrees C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also maintains good low temperature toughness. SS 321H Pipes is the higher carbon (0.04–0.10) version of the alloy. It was produced to improve creep resistance and for higher strength at temperatures above 1000 degrees F (537 degrees C). In most occurrences, the carbon content of the pipes enables dual certification.s

Stainless Steel UNS S32100 / S32109 Seamless Pipes cannot be hardened by heat treatment, just by cold working. It can be effectively welded and processed by standard shop fabrication practices. SS 321 Seamless Pipes can be utilized in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at high temperatures. Alloy 321 opposes polythionic acid stress corrosion cracking in hydrocarbon service. It can also be used in chloride or fluoride free caustic solutions at moderate temperatures. 321 SS Pipes does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service.
