Products Description
This product is reinforced with stable titanium (Ti) elements, featuring excellent intergranular corrosion resistance and high-temperature strength. The 321 stainless steel wire can maintain excellent mechanical properties even at temperatures ranging from 500°C to 800°C, and is widely used in aerospace, chemical equipment, power plant boilers, automotive exhaust systems, and high-temperature structural components, etc.
Product Features and Advantages
- Excellent high-temperature resistance: It can maintain good strength and ductility even in continuous high-temperature conditions.
- Anti-intergranular corrosion: The stabilization effect of titanium effectively prevents the formation of carbides during welding or heating.
- Mechanical properties are stable: high strength and high toughness coexist, making it suitable for demanding industrial applications.
- Easy processing and weldable: Possess excellent forming performance and can be compatible with various drawing, winding and welding processes.
- Widely applied: It can be used in high-temperature springs, filter screens, heat-resistant resistance wires, welding filler materials, etc.
