Characteristic

Corrosion Resistance:

304V stainless steel wire is highly resistant to corrosion, making it suitable for applications in aggressive environments, such as marine and chemical processing industries.

Strength and Formability:

The addition of vanadium enhances the strength of 304V, making it ideal for applications requiring durability. Simultaneously, it retains the formability typical of the 304 stainless steel family.

Biocompatibility:

This alloy's biocompatibility makes it invaluable in medical applications. It is commonly used in the production of surgical instruments and orthodontic appliances.

Temperature Stability:

304V maintains its mechanical properties at elevated temperatures, expanding its utility in applications exposed to heat.

Applications

304V steel has a variety of applications in the medical field, mainly including medical devices, surgical implants, surgical instruments, etc. 304V steel is a medical stainless steel material that adopts a duplex smelting process. It is smelted by electric arc furnace and vacuum arc remelting to obtain a more uniform chemical composition, reduce gaps and contaminants, and thus improve the purity and uniformity of the material.

Specific application areas Medical devices: 304V steel is often used to make medical devices such as orthodontic archwires, catheters, guidewires, surgical instruments, etc. Its flexibility and sturdiness make it perform well in these applications

Surgical implants: Due to its excellent strength and corrosion resistance, 304V steel is also used to make surgical implants such as mandrels, springs and needles.
Other medical devices: In addition, 304V steel is also used to make non-implantable medical devices such as probes and catheters, which require high-strength and corrosion-resistant materials.
