Stainless Steel Grade 321 SS alloy
Type 321 stainless steel plate outperforms Type 304 stainless steel plate in terms of high-temperature stress-rupture and creep resistance.
Stainless Steel Grade 321 SS alloy is a Ni-Cr-Mo type austenitic stainless steel plate. Because of the addition of titanium, its grain boundary corrosion resistance and high temperature strength are better. Titanium can also effectively control the formation of chromium carbide!
The stabilizing effect of titanium gives 321 stainless steel significant advantages at temperatures below 650°C:
Aero-engine combustion chamber liners represent a classic application for 321 stainless steel:
What key factors would overturn your decision?
Caution with sulfur-containing media
Stainless Steel Sheet 321 Titanium stabilization in sulfur-containing media may accelerate pitting corrosion. Regular sheet materials require additional treatment to meet the requirements.
After purchasing the Stainless Steel Grade 321 SS alloy, you might have underestimated these supporting equipment.
For instance, when working in a high-temperature environment, ordinary gloves are unable to offer adequate protection, while professional heat-resistant protective gloves can effectively prevent the risk of burns.
