ASTM A312 Seamless Pipe Manufacturer

Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality ASTM A312 Seamless Pipe, which has excellent forming and welding characteristics. The austenitic structure also gives ASTM A312 Austenitic Stainless Steel Pipes excellent toughness, even down to cryogenic temperatures. These ASME SA 312 Austenitic Stainless Steel Seamless Pipes is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. ASTM A312 Austenitic Stainless Steel Welded Pipes also has outstanding welding characteristics, where post – weld annealing is not required when welding thin sections.

This is combined with better creep properties at temperature and these ASME SA 312 Austenitic Stainless Steel Heavily Cold Worked Pipes is very tough and ductile. With its high chromium content, ASTM A312 Austenitic SS Pipes offers good corrosion resistance to increase high temperature properties. These ASME SA 312 Austenitic SS Seamless Pipes is manufactured using finest grade raw material available to ensure international quality. ASTM A312 Austenitic SS Welded Pipes are considered to be non – sparking and suitable for equipment designed to handle explosives, petroleum, and chemical and gas products.

These ASME SA 312 Austenitic SS Heavily Cold Worked Pipes were developed originally for the chemical industry because of their exceptional resistance to corrosion in many liquids. GTAW or PAW should not be done without a filler metal in ASME SA 312 Pipes unless post weld cleanup is possible, where a heat input should be used for SMAW or GTAW.

Scope And Manufacturing

 

ASTM A312 specification covers seamless pipe and welded pipe for austenitic stainless steel. These high performance austenitic stainless steels have a fully austenitic microstructure in the quench annealed condition. These grades are sometime alloyed with nitrogen to improve strength or with sulphur to improve machinability. 904L was originally developed to withstand environments involving dilute sulphuric acid and it is one of the few stainless steels that, at temperatures up to 35°C, provides full resistance. This is mainly due to the high contents of chromium, nickel, molybdenum and nitrogen.
