Introduction to the Performance of 303 Stainless Steel

‌Shenzhen Huachang Weiye Metal Materials Co., Ltd.‌
‌Product Introduction: 303 Stainless Steel Bars‌

‌Key Features of 303 Stainless Steel Bars‌

1. ‌Superior Machinability‌

   • Enhanced with sulfur (S) and selenium (Se), 303 stainless steel bars exhibit exceptional cutting performance, ideal for high-speed automatic lathes and precision machining of complex components like bolts, nuts, and threaded parts‌.
   • Achieves smooth surface finishes, reducing post-processing requirements‌.

2. ‌Corrosion Resistance‌

   • Maintains good resistance to oxidation and mild corrosive environments, comparable to 304 stainless steel, though slightly reduced due to sulfur content‌.

3. ‌Mechanical Properties‌

   • ‌Tensile Strength‌: ≥515–520 MPa
   • ‌Yield Strength‌: ≥205 MPa
   • ‌Elongation‌: ≥40%
   • ‌Hardness‌: HRB 90–100 / HRC 20–25‌13.

4. ‌Thermal Stability‌

   • Resists high-temperature bonding, suitable for applications requiring thermal durability‌.

5. ‌Customization Flexibility‌

   • Available in ‌round bars, hex bars, square bars, and flats‌, with options for bright or black surfaces‌.

‌Applications‌

303 stainless steel bars are widely used in industries demanding precision, durability, and corrosion resistance:

• ‌Automotive & Aerospace‌: Shafts, valve components, and aircraft fittings‌.
• ‌Medical & Food Processing‌: Threaded surgical instruments, machinery parts requiring hygienic surfaces‌.
• ‌Industrial Fasteners‌: Bolts, nuts, and bearings for automated equipment‌.
• ‌Electronics & Petrochemicals‌: Components exposed to mildly corrosive environments‌.
