Product Overview
The 321 stainless steel sheet is a high-performance, high-temperature-resistant material that is widely used in industries requiring superior heat resistance and corrosion protection. This stainless steel sheet is stabilized with titanium, which prevents intergranular corrosion, especially in high-temperature applications. With excellent mechanical properties, superior oxidation resistance up to 900°C (1652°F), and outstanding durability, 321 stainless steel sheet is the material of choice for aerospace, exhaust systems, and industrial equipment exposed to high temperatures.
This stainless steel grade is part of the austenitic family and is comparable to 304 stainless steel but offers enhanced resistance to oxidation and creep. It is particularly beneficial for environments where prolonged exposure to high heat is required. Its titanium stabilization prevents carbide precipitation, making it highly resistant to intergranular corrosion, even in highly acidic or chloride-containing environments.

Processing & Applications
-
Cold Rolling: Precision cold rolled stainless steel plate/sheet is manufactured to ensure uniform thickness, smooth surfaces, and enhanced mechanical properties. The cold rolling process increases strength and hardness while improving surface finish, making it ideal for high-precision applications.
-
Annealing & Pickling: The annealing process enhances ductility, improving formability and corrosion resistance. Pickling removes impurities, surface oxides, and contaminants, ensuring a clean and high-quality surface.
-
Cutting: Advanced laser and plasma cutting techniques allow for custom shapes and sizes, meeting specific industrial requirements.
-
Machining & Forming: The 321 stainless steel sheet is easily machinable and can be formed into complex structures while maintaining its superior properties. Its excellent weldability makes it a preferred material in industrial applications.
-
Heat Treatment: Unlike some stainless steels, 321 stainless steel sheet is not hardenable by heat treatment but can be strengthened through cold working processes.
