Stainless Steel wires find their application in various industries owing to their good corrosion resistance and high durability and strength. These stainless steel wires are available in various grades having their unique properties.
In this article, we will explore grade 310 stainless steel wires.
About 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).
Chemistry Typical
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 Corrosion Resistance Wire
310 stainless steel 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.
- Plated: 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 stainless steel 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.
