321 stainless steel sheet is a titanium-stabilized material with corrosion resistance comparable to 304/304L stainless steel. SS 321 material is commonly used in high-temperature applications ranging from 800 to 1500°F. Additionally, 1.4541 stainless steel incorporates titanium to inhibit chromium carbide formation, delivering excellent intergranular corrosion resistance. Our supplier-manufacturer maintains stock of 321 sheet in various dimensions, certified to AMS 5510 and ASTM A240.

Stainless Steel 321 Vs 304
321 stainless steel has added Ti and is designed for high temperatures; while 304 stainless steel is suitable for medium-temperature environments and is less expensive.
1.4571 vs 1.4541
1.4571 (316Ti) contains Mo and is more resistant to chloride and acidic environments. 1.4541 (321), while, is more suitable for environments with lower corrosiveness.
