Stainless Steel 321/321H Pipes

Silver Tubes is a leading trader and manufacturer of Stainless Steel 321 Pipes/ Stainless Steel 321H Pipes, which is stabilized against chromium carbide formation by the addition of titanium. 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.
