314 Fine Wire Mechanical Properties

The mechanical properties of 314 fine wire, a heat-resistant alloy, typically include:

  1. Tensile Strength: Generally ranging from 515 to 690 MPa (75,000 to 100,000 psi). This is the maximum stress the wire can withstand while being stretched or pulled before breaking.
  2. Yield Strength: Typically around 205 to 260 MPa (30,000 to 38,000 psi). This is the stress at which the wire begins to deform permanently (plastically) without fracturing.
  3. Elongation: Usually between 40% to 45%. 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 95 HRB (Rockwell B hardness).
  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. This can vary depending on factors such as wire diameter, surface finish, and operating conditions.

These mechanical properties make 314 fine wire suitable for use in applications where high-temperature strength, durability, and resistance to oxidation are required, such as furnace components and chemical processing equipment.
