321 Stainless is available in the following forms
• Sheet
• Plate
• Bar
• Pipe & Tube
• Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lapjoints,
long welding necks, socket welds, elbows, tees, stub-ends, returns,
caps, crosses, reducers, and pipe nipples)
• Weld Wire
321 Stainless Steel Overview
Stainless 321 is a heat resistant, titanium stabilized, austenitic
alloy that's commonly used for service in the 1000°-1600°F
temperature range. 321 stainless is primarily used in applications
that involve continuous and intermittent service temperatures
within the carbide precipitation range of 800°-1500°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.
What are the characteristics of 321 Stainless?
• Oxidation resistant to 1600°F
• Stabilized against weld heat affected zone (HAZ) intergranular
corrosion
• Resists polythionic acid stress corrosion cracking
