Priminox Overseas is a known stockist of STAINLESS STEEL 321 / 321H PIPES AND TUBES, which are accredited to internationally approved quality standards for applications. ASTM A312 321 Seamless Pipes are the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium or Niobium additions. SS 321 Seamless Tubes is a steadied steel that provides as its prime benefit of an outstanding confrontation to inter – granular erosion ensuing acquaintance to heats in chromium carbide precipitation array from 800 Degree F to 1500 Degree F. Grade 321 Welded Pipes is almost same as Grade 304 Welded Pipes; however, covers an addition of Titanium greater than the content of carbon. This titanium addition in Type 321 Welded Tubes reduces or prevents carbide precipitation during welding and in 800 Degree F – 1500 Degree F service. 321H Stainless Steel Seamless Pipes is titanium stabilized austenitic stainless steel that is known for its general corrosion resistance. Titanium is added to the composition of AISI 321H Seamless Tubes to suppress grain boundary chromium carbide precipitation and reduce susceptibility to intergranular corrosion. This titanium comportment ASTM A358 Stainless Steel 321H Welded Pipes are alleviated in contradiction of carbide precipitation and considered for process within the destructive heat array where carbide precipitation progresses.
