321 Stainless Steel Pipe

Hunan Great supply a wide range of SS 321 / SS 321H Pipes and Tubes to our clients, which are sturdy in construction and ensure long service life.

Stainless Steel 321 Pipes (UNS S32100) is the basic austenitic 18/8 steel (Stainless Steel 304) stabilised by Titanium (321) or Niobium (347) additions. Stainless Steel 321 Tubes is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500 Degree F (427 to 816 Degree C).

The addition of titanium in 321 stainless steel give some desired characteristics:
Prevents harmful carbide precipitation in the heat affected zone (HAZ) of the weld area
Imparts partial immunity to inter granular corrosion
Reduced embrittlement in the HAZ of the weld area

SS 321H Pipes (UNS S32109) is a modification of SS 321 Tubes with a higher carbon content, to provide improved high temperature strength. SS 321H Tubes is the higher carbon (0.04 - 0.10) version of the alloy.

Responds well to hardening by cold working
Good welding characteristics
Excellent corrosion resistance in a wide variety of corrosive media
High creep & stress rupture properties
