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 ‌: <000000>ge;515–520 mpa
   • ‌ Yield Strength ‌: <000000>ge;205 MPa
   • ‌ Elongation ‌: <000000>ge;40%
   • ‌ Hardness ‌: HRB 90–100 / HRC 20–25‌ 1 3

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.
