321 stainless steel plate

321 stainless steel plate is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

Like other austenitic grades, 321 stainless steel plate has excellent forming and welding characteristics, which is readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing is not required. They also have excellent toughness, even down to cryogenic temperatures. 321 stainless steel plate does not polish well, so is not recommended for decorative applications.

321 stainless steel plate Chemical Composition:

C% Si% Mn% P% S% Cr% Ni% Ti%
≤ 0.08 ≤ 0.75 ≤2.00 ≤0.045 ≤0.03 17-19 9-12 ≥5

321 cold rolled stainless steel 2B plate (thickness /mm): Cold rolled 2B plate: 0.1—8.0 Hot rolled No.1 plate: 3—125

Surface finish :2B , 8K, sanding (drawing, pulling sand), titanium, snow sand.

A limitation with 321 stainless steel plate is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications. 

The performance of 321 stainless steel plate and 304 stainless steel is very similar, all add to the titanium raw material, better resistance to grain boundary corrosion and high temperature strength. The addition of titanium makes an effective control of the chromium carbide formation. 321 stainless steel plate high temperature stress rupture properties and stress mechanical properties are superior to 304 stainless steel.Ti in 321 stainless steel plate exists as stable, but it is also hot strong steel . Much better than the 316L stainless steel at high temperatures.

BEBON STEEL can offer a lot of 321 stainless steel plate, otherwise, including its chemical composition and mechanical propertity. If you are interested in 321 stainless steel plate spot, please contact BEBON STEEL.
