321 Stainless Steel Tool Wrap
Our 321 Stainless Steel Tool Wrap is the ideal solution for heat treating tooling. Just wrap the tooling with the edges crimped to form an envelope. This creates an air-tight package that will prevent the loss of surface carbon. Don’t let your tooling become scaled or damaged. Protect your investment while eliminating charcoal and sawdust box packaging with 321 Tool Wrap. Contact us today for a quote or visit our pricing page for stock inventory items.
Alloy321 (UNS S32100) is a stabilized stainless steel 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 . Type 321 is stabilized against chromium carbide formation by the addition of titanium.
While 321 continues to be employed for prolonged service in the 800 to 1500°F temperature range, 304L has supplanted this stabilized grade for application involving only welding or short time heating.
321stainless steel is also advantageous for high temperature service because of its good mechanical properties. 321 stainless steel offers high creep and stress rupture properties than 304 and, particularly 304L which might also be considered for exposures where sensitization and intergranular are concerns. This results in higher elevated temperature allowable stresses for this stabilized alloy for ASME Boiler and pressure vessel code applications. 321 alloy has a maximum use temperature of 1500°F for code applications like 304, where 304L is limited to 800°F
