About 316 Spring Wire

316 spring wire is a stainless steel wire renowned for its superior corrosion resistance and spring properties. Composed primarily of chromium, nickel, and molybdenum, it offers high tensile strength and elasticity, making it ideal for springs, fasteners, and other applications requiring resilience and durability in corrosive environments.

 

316 Spring Wire chemical composition

The chemical composition of 316 spring wire typically includes:

  • Chromium (Cr): 16-18%
  • Nickel (Ni): 10-14%
  • Molybdenum (Mo): 2-3%
  • Carbon (C): 0.08% maximum
  • Manganese (Mn): 2% maximum
  • Silicon (Si): 1% maximum
  • Phosphorus (P): 0.045% maximum
  • Sulfur (S): 0.03% maximum
  • Iron (Fe): Balance

This composition ensures the wire possesses the necessary properties for spring applications, including high corrosion resistance and mechanical strength.

 

316 Spring Wire physical properties

The physical properties of 316 spring wire typically include:

  1. Density: Approximately 8.00 g/cm³.
  2. Melting Point: Around 1370-1400°C (2500-2550°F).
  3. Tensile Strength: Typically ranging from 520 to 860 MPa (75,000 to 125,000 psi).
  4. Elongation: Usually between 40% to 60%. This measures the percentage increase in length a material can undergo before breaking under tension.
  5. Modulus of Elasticity: Around 193 GPa (28 x 10^6 psi). This represents the stiffness or rigidity of the material; it measures the amount of deformation a material experiences in response to an applied force.
  6. Hardness: Typically in the range of 201 to 241 HB (Brinell Hardness). This indicates the resistance of the material to indentation or scratching.

These properties make 316 spring wire suitable for various applications where high tensile strength, corrosion resistance, and elasticity are required, such as springs, fasteners, and wire forms.

 

316 Spring Wire mechanical properties

The mechanical properties of 316 spring wire typically include:

  1. Tensile Strength: Typically ranging from 520 to 860 MPa (75,000 to 125,000 psi). This measures the maximum amount of tensile (stretching) stress a material can withstand before breaking.
  2. Yield Strength: Typically around 190 to 310 MPa (27,500 to 45,000 psi). This is the stress at which a material begins to deform plastically without any increase in the load.
  3. Elongation: Usually between 40% to 60%. This measures the percentage increase in length a material can undergo before breaking under tension.
  4. Modulus of Elasticity: Approximately 193 GPa (28 x 10^6 psi). This represents the stiffness or rigidity of the material; it measures the amount of deformation a material experiences in response to an applied force.
  5. Hardness: Typically in the range of 201 to 241 HB (Brinell Hardness). This indicates the resistance of the material to indentation or scratching.

These mechanical properties ensure that 316 spring wire can withstand various mechanical stresses while maintaining its integrity and spring properties, making it suitable for a wide range of applications in industries such as automotive, aerospace, and manufacturing.
