Silver Tubes is one of the most prominent industries that are dealing as the top-ranking manufacturer, supplier, stockiest of Stainless Steel 321 Pipes/ Stainless Steel 321H Pipes, which is stabilized against chromium carbide formation by the addition of titanium. As they are customer focused so they are making use of stunning quality of raw materials that are bought from the reputable merchants. This grade SS pipes are having various good features like withstanding heavy loads, rugged construction, pitting resistance, oxidation resistance, stress corrosion cracking resistance, crevice corrosion resistance, machinability, weldability, dimension accuracy etc. Type 321 Pipes is a titanium-stabilised version of 304, used in particular applications within the sensitizing temperature range. Type 321H Pipes is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperature in the chromium carbide precipitation range from 800 Degree F to 1500 Degree F (427 Degree C to 816 Degree C). Grade 321 Pipes is not subject to weld decay intergranular corrosion when exposed to mildly corrosive environments. Resistance to sensitization of Grade 321H Pipes, coupled with its higher strength at high temperature makes it suitable in application where it will become sensitized, or where it has insufficient hot strength.

The welded SS 321 Pipes must never be used in highly oxidizing environments as it is liable to 'Knife-line' attack. A limitation with SS 321H Pipes is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. 321 Stainless Steel Pipes is a much better option in operating temperature environments in excess of 500 Degree C and therefore has its own merits. 321H Stainless Steel Pipes offers higher creep and stress rupture properties and, particularly, also be considered for exposure where sensitization and intergranular corrosion are concern.

The standard specification is ASME SA 358, ASME SA 312, ASTM A 312 and ASTM A 358. The dimension of it is ASME, ASTM, and API. The size is normal 1/8"NB to 30"NB IN, SS 231/321H pipes ½" NB to 16"NB, EFW 321/321H pipes 6" NB to 100" NB and ERW 321/321H pipes ½" NB to 24"NB. The schedule is SCH 20, 40, 30, 60, 80, 120, 160, and 140, STD, XS and XXS. The forms are hydraulic, square, round, rectangle etc. The type of pipes is welded, LSAW, ERW, fabricated and seamless. The length is single and double random and in cut length. The ends are treaded, beveled and plain ends.

The Stainless Steel 321/321H Pipes before getting into the hand of buyers is undergoing various testing that is including PMI test, IGC test, flattening test, flaring test. Also, the other tests like the macro test, micro test, radiography test, hydrostatic test, chemical test, mechanical test etc are making it ideal for various critical applications. This is also greatly responsible for enhancing the quality of this grade pipes.
