Stainless Steel 310 Properties

Stainless Steel 310 stands out for its exceptional resistance to high temperatures, corrosion, and oxidation. At Ferrobend, we specialize in the manufacturing of Stainless Steel 310 products that meet the highest industry standards, ensuring quality and performance for a wide range of applications. Stainless Steel 310 is an austenitic grade of stainless steel known for its outstanding heat resistance and excellent strength at high temperatures. It is primarily composed of chromium (25-30%) and nickel (19-22%), which provide the alloy with a combination of heat resistance, corrosion resistance, and good mechanical properties at elevated temperatures. Stainless Steel 310 is often used in environments where both heat and corrosion resistance are critical. This high-performance alloy is especially well-suited for applications in industries like petrochemical, power generation, aerospace, and food processing, where exposure to extreme temperatures and corrosive environments is common. Its ability to maintain strength at high temperatures—up to 1100°C in intermittent service—makes it the material of choice for many industrial and manufacturing processes

At Ferrobend, we are committed to providing the highest-quality Stainless Steel 310 products that meet the stringent requirements of various industries. Our state-of-the-art manufacturing processes, combined with a team of skilled professionals, ensure that we can deliver premium products with exceptional quality and performance.

Heat Resistance:

  • Good oxidation resistance at temperatures up to 1700oF (927 oC)
  • Continuous use at temperatures above 1400oF (760oC) is not usually recommended due to carbide precipitation which can lead to irregular scaling
  • Does not have a low carbon content so it is also vulnerable to sensitization

Welding Characteristics:

  • Not generally recommended, but may be welded with some difficulty
  • May be welded with Alloy 310 electrodes
  • Should be annealed after welding to re-dissolve precipitated carbides

Machinability:

  • High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell
  • Will work harden; therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.

Applications:

  • Nuts and bolts
  • Aircraft fittings
  • Gears
  • Screws
  • Shafts
  • Electrical switchgear components
  • Bushings
