Product Details

General description:

Stainless 321 is a heat resistant, titanium stabilized, austenitic alloy which is similar to 304. Such alloy is mainly used in the temperature of 1000 -1600°F. Type 321 is similar to type 304 stainless but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in the 800 -1500°F service conditions. In order to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking in service temperatures at 1500 - 1650°F an air cool may be used.


The characteristics of Stainless steel 321:

·Oxidation resistant to 1600°F

·Stabilized against weld heat affected zone (HAZ) intergranular corrosion

·Resists polythionic acid stress corrosion cracking

Production process of stainless 321 fastener:

1st melting → 2nd remelting → hot forging → hot rolling → peeling → polishing→upsetting→thread rolling


Application of stainless 321 fastener:

· Thermal oxidizers;

· High temperature chemical process equipment;

· Expansion joints etc.
