Product Features

Excellent High-Temperature Resistance

321 stainless steel strip performs well in continuous high-temperature environments. The addition of titanium helps stabilize the material structure and reduces carbide precipitation, allowing the strip to maintain strength and durability under thermal stress.

Strong Intergranular Corrosion Resistance

Because titanium combines with carbon elements, 321 stainless steel effectively prevents intergranular corrosion after welding. This feature makes it suitable for welded structures and heat-affected applications.

Good Oxidation Resistance

The material provides reliable oxidation resistance at elevated temperatures. It can withstand harsh industrial environments where heat and oxidation are common.

Excellent Mechanical Properties

321 stainless steel strip offers good toughness, ductility, and formability. It is suitable for bending, stamping, cutting, and welding processes, supporting various manufacturing needs.

Stable Welding Performance

This stainless steel strip has excellent weldability without requiring post-weld annealing in many applications. It is ideal for fabricating components exposed to high temperatures.

Product Advantages

• Stable performance in high-temperature environments
• Longer service life under thermal cycling conditions
• Reduced risk of weld corrosion and cracking
• Smooth surface finish and precise thickness tolerance
