304 Stainless Steel Wire
304 stainless steel wire is made of 304 stainless steel (06Cr19Ni10) of ASTM A276 standard, and is a round or oval cross-section metal wire made by cold drawing, annealing and other processes. It has excellent corrosion resistance, high strength and good processing performance. It is suitable for harsh environments such as chemical, medical, and food. It is an austenitic stainless steel containing Cr, Ni, C, Mn, Si, P, and S elements. Wanzhi Steel specializes in the production of 304 stainless steel wire, with a large number of conventional diameters in stock, supports surface treatments such as bright and matte, and accepts customized solutions.

- Good processability: Strong ductility, can be easily stamped, bent, weaved and other operations, not easy to break or deform after processing.
- Excellent high temperature resistance: It can still maintain stable performance in high temperature environment below 800℃, and the short-term use temperature can reach 1000℃ (long-term exposure should be avoided).
- Non-magnetic or weak magnetic: It is non-magnetic in the solution treatment state, and may produce weak magnetism after cold processing, which is suitable for scenes sensitive to magnetism.
- Beautiful and easy to maintain: No additional coating is required to keep the surface bright and beautiful, and it is simple to clean, which is suitable for fields with high requirements for appearance.
- High strength and toughness: Tensile strength ≥515 MPa, yield strength ≥205 MPa, suitable for occasions that require load-bearing or impact resistance.
