Stainless Steel 321/321H Sheets Plates

SS 321 Sheets continues to be employed for prolonged service in the 800 Degree F to 1500 Degree F (427 Degree C to 816 Degree C) temperature range. Slightly tougher than other alloys, SS 321 Plates will produce the same tough stringy chips. A preheating is not necessary for SS 321 Coils, where a heat treatment after welding is normally not usual. 321 Stainless Steel Sheets has good creep strength up to 1500 Degree F, along with good resistance to inter-granular corrosion in the as welded condition.

Product information

Alloy 321 (UNS S32100) is stabilized stainless steel plate 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°F (427 to 816°C). Alloy 321 stainless steel plate is stabilized against chromium carbide formation by the addition of titanium.
Alloy 321 stainless steel plate is also advantageous for high temperature service because of its good mechanical properties. Alloy 321 stainless steel plate offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.

Formability
Type 321 can be readily formed and drawn, however, higher pressures are required and more springback is encountered than for carbon steel and ferritic stainless steels. Like other austenitic stainless steels,Type 321 work hardens quickly and may require annealing after severe forming.The presence of certain alloying elements can make Type 321 more difficult to form than other austenitic grades such as 301, 304 and 305.

Heat Treatment
Type 321 is non-hardenable by heat treatment.Annealing: Heat to 1750 – 2050 °F (954 – 1121°C), then water quench or air cool.

Weldability
The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to avoid weld ”hot cracking” by assuring formation of ferrite in the weld deposit. This particular alloy is generally considered to have comparable weldability to Types 304 and 304L. A major difference is the titanium addition that reduces or prevents carbide precipitation during welding. When a weld filler is needed, either AWS E/ER 347 or E/ER 321 is most often specified.Type 321 is well known in reference literature and more information can be obtained in this way.
