321 stainless steel is a common high-temperature corrosion-resistant stainless steel material, mainly composed of chromium, nickel and titanium.The inclusion of titanium in the composition enhanced stability against chromium carbide precipitation, making 321 stainless steel particularly well-suited for applications involving elevated temperatures.
The addition of titanium not only enhances the material's resistance to intergranular corrosion but also makes it well-suited for applications in high-temperature environments.In addition,the 321 steel added with titanium to enhance high temperature resistance.321 stainless plates have the characteristics of corrosion resistance, high strength, and easy plasticity, it can also withstand long-term use in high-temperature environments. Therefore, 321 stainless steel is widely used in aerospace, chemical industry, pharmaceutical and other fields.
321 stainless sheet is a high-temperature corrosion-resistant material with good corrosion resistance and weldability.
Advantages of 321 stainless steel plate:
1. Good corrosion resistance: 321 stainless steel plate has excellent corrosion performance in high temperature, high pressure and corrosive gas environments.
2. Good weldability: 321 stainless plates can be welded by various conventional welding methods, without welding seams and connecting parts with low metal material strength.
3. Good heat resistance and stability: 321 stainless steel sheet not only has good mechanical properties at room temperature, but also maintains good corrosion resistance and plastic toughness at high temperatures.
4. Excellent processing performance: 321 stainless sheets are easy to process and form, and can meet the production needs of complex parts.
