310 Stainless Steel Wire

310 stainless steel is an austenitic stainless steel alloy. It has a good amount of nickel and chromium, making it resistant to heat and oxidation. It can, therefore, be used at high temperatures without deterioration. It operates quite well at a temperature as high as 2000°F (1093°C). It also shows good corrosion resistance and retains much of its strength at room temperature. It can also perform well at very low temperatures as low as -450 °F (-268°C).

Chemical Composition:

The chemical composition of grade 310 stainless steel is as follows:

  • Carbon: 0.25 max
  • Phosphorus: 0.045 max
  • Silicon: 1.50 max
  • Nickel: 19.00-22.00
  • Manganese: 2.00 max
  • Sulfur: 0.030 max
  • Chromium: 24.00-26.00
  • Molybdenum: 0.75 max
  • Copper: 0.50 max
  • Iron: Balance

310 Stainless Steel Corrosion Resistance Wire:

310 ss wire is highly corrosion-resistant and is available in several finishes:

  • Extra Clean (XC): Also referred to as “bright annealed” or “bright annealed and cold rolled,” which makes the surface bright and clean.
  • Grease (round wire only): Offers an “Ultra bright” finish.
  • Soap (round wire only): Soap is present in the manufacturing process and left on as a lubricant. This could be very handy during the forming process.
  • Plating: Plating is done through several options for varying uses.

310 Stainless Steel Wire Applications:

Owing to its high corrosion and temperature resistance, it is used in various applications. Some of the common applications of grade 310 wires are:

  • Kilns
  • Heat exchangers
  • Furnace parts, muffles, and retorts, annealing covers
  • Food processing equipment
  • Cryogenic structures.

310 ss wire is a durable, high-heat resistant item that is used in several different applications where either extremely high heat or extremely low cold temperatures occur.
