304L Redraw Wire mechanical properties

The mechanical properties of 304L redraw wire, a low-carbon stainless steel alloy, typically include:

  1. Tensile Strength: Typically ranging from 485 to 655 MPa (70,000 to 95,000 psi). This is the maximum stress the wire can withstand while being stretched or pulled before breaking.
  2. Yield Strength: Generally around 170 to 275 MPa (25,000 to 40,000 psi). This is the stress at which the wire begins to deform permanently (plastically) without fracturing.
  3. Elongation: Typically between 40% to 60%. 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 70 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 304L redraw wire suitable for various applications requiring strength, ductility, and corrosion resistance, such as springs, fasteners, and wire forms.
