AISI 302 Stainless Steel Wire

AISI 302 Stainless Steel Wire

AISI 302 Stainless Steel Wire is made from austenitic stainless steel, with a composition of approximately 18% chromium and 8% nickel. It offers excellent corrosion resistance, high tensile strength, and good formability. The wire is commonly used in automotive, aerospace, and medical equipment manufacturing industries. Its primary applications include springs, wire mesh, fasteners, and woven wire products.

Heat Treatment

Heat Treatment

Stainless steel wire product heat treatment
  1. Normalizing
    • Not commonly applicable for 302 stainless steel wire.
  2. Annealing
    • Heated to temperature between 1010°C and 1120°C (1850°F to 2050°F) and then slowly cooled in air.
    • Used to soften the material, improve ductility, and remove internal stresses.
  3. Solution Annealing
    • Heated to a temperature from 1010°C to 1120°C (1850°F to 2050°F) followed by rapid quenching.
    • Restore and improve corrosion resistance.
  4. Quenching
    • After solution annealing, the material is rapidly cooled in water or air.
    • Retain a ductile, corrosion-resistant microstructure.
  5. Stress Relieving
    • Heated to a temperature between 290°C and 425°C (550°F to 800°F) and then slowly cooled.
    • Reduce residual stresses from prior cold working processes.

Characteristic

Characteristic

  • High Corrosion Resistance: 302 stainless steel resists rusting and oxidation, making it suitable for environments exposed to moisture, chemicals, or other corrosive elements.
  • Good Heat Resistance: It maintains its strength and resists scaling at temperatures up to about 870°C (1600°F), suitable for moderately high-temperature applications​.
  • Non-Magnetic (Annealed State): In its annealed form, 302 stainless steel is non-magnetic, which is useful in certain electronic or precision applications.
  • Good Tensile Strength: It offers high tensile strength, making it durable and capable of withstanding significant mechanical stress without breaking.
  • Excellent Ductility: This material can be easily drawn or formed into wire without cracking or losing structural integrity, ideal for applications like springs and fasteners.
