302 Redraw Wire mechanical properties

The mechanical properties of 302 redraw wire, a stainless steel alloy, typically include:

  1. Tensile Strength: Typically ranging from 520 to 860 MPa (75,000 to 125,000 psi). This is the maximum stress the wire can withstand while being stretched or pulled before breaking.
  2. Yield Strength: Generally around 205 to 240 MPa (30,000 to 35,000 psi). This is the stress at which the wire begins to deform permanently (plastically) without fracturing.
  3. Elongation: Typically between 40% to 50%. This is the measure of how much the wire can stretch before it breaks, indicating its ductility.
  4. Hardness: Varies depending on the manufacturing process and heat treatment, typically ranging from 85 to 90 HRB (Rockwell B hardness).
  5. Modulus of Elasticity: Approximately 193 GPa (28 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 302 redraw wire suitable for various applications requiring strength, ductility, and corrosion resistance, such as springs, fasteners, and wire forms.
