Recommended annealing temperature for TP321 and 321 wrought stainless steel: 1040 °C (1900 °F); Minimum 1095 °C (2000 °F) for cold-worked 321H and 1050 °C (1095 °F) for hot-finished 321H; Stress-relieving treatments
The coefficient of thermal expansion of 321 plate between 32℉ and 1,000℉ is 1.03in x10^-5. The specific heat of 321 stainless steel plate is 0.194 BTU/IBM. Specifications. Applications and Usage. There are many uses for these grades of stainless steel plate, especially in environments which require higher temperatures.
Jan 10, 2023 · It has great formability, weldability, and corrosion resistance compared to typical alloys. This unique alloy can withstand harsh temperatures up to 1500°F due to its high nickel and chromium content. As a result, 321 stainless steel is commonly used in applications where heat treatment isn’t suitable or economical.
Heat Treatment. Heat temperature range is limited to 950-1120°C and cool rapidly for maximum corrosion resistance, it cannot be hardened by heat treatment. Dual Certification. Dual 321/321H stainless steel is usually used for high-temperature applications. Notes.
Aug 15, 2023 · 321 stainless steel is capable of withstanding the formation of chromium carbide between 426 ℃ and 815 ℃ due to the addition of titanium as a stabilizing element. As a result, it exhibits better resistance to intergranular corrosion, high temperature performance, and higher resistance to creep and stress fractures than 304 and 304L.
Hot Forming. Working temperatures of 2100 – 2300°F (1149 – 1260°C) are recommended for forging, upsetting and other hot working processes. Alloy not suitable for work at temperatures below 1700°F (927°C). Material must be water quenched or fully annealed after working to re-attain maximum corrosion resistance.
Stainless Steel 321 is a Titanium stabilised Austenitic stainless offering excellent strength and resistance to intergranular corrosion. 321 is the material of choice for applications in the temperatures up to 900 deg C. 321 is not hardened by heat treatment but mechanical properties can be improved considerably by cold working, with a subsequen...
