316L fine wire mechanical properties

The mechanical properties of 316L fine wire, a type of stainless steel wire, include:

  1. Tensile Strength: Typically ranging from 485 to 620 MPa (70,000 to 90,000 psi). This is the maximum stress that the wire can withstand while being stretched or pulled before breaking.
  2. Yield Strength: Typically around 170 to 290 MPa (25,000 to 42,000 psi). This is the stress at which the wire begins to deform permanently (plastically) without fracturing.
  3. Elongation: Generally between 40% to 60%. This is the measure of how much the wire can stretch before it breaks, indicating its ductility.
  4. Hardness: Typically ranging from 170 to 190 Brinell hardness (HB). This indicates the resistance of the wire to indentation or scratching.
  5. Modulus of Elasticity: Approximately 200 GPa (29 x 10^6 psi). This is the measure of the wire’s stiffness or how much it deforms under stress.
  6. Fatigue Strength: The ability of the wire to withstand repeated loading cycles without failure. Stainless steel generally exhibits good fatigue strength.

These mechanical properties make 316L fine wire suitable for various applications where strength, ductility, and corrosion resistance are essential, such as in medical devices, automotive components, and electronic connectors.
