  • 310SS chemistry & specifications

Designed for high temperature applications, 310 stainless steel screws provide high temperature oxidation resistance to 2000°F under mild cyclic conditions. An economic alternative to nickel alloys like alloy 330 or Inconel, 310 screws provide slightly less strength and temperature resistance – but at a significantly lower price point.  Alloy 310 can be used in moderately caburizing, moderately oxidizing, nitriding, cementing and thermal cycling applications when not used at the maximum service temperature. 310SS screws also have good resistance to sulfidation and other forms of hot corrosion.  Although primarily known for its high temperature properties, 310 stainless steel also provides excellent performance at cryogenic temperatures, with toughness down to -450˚F. Though 310 is ideal for high temperature use, it should not be exposed to the severe thermal shock of repeated liquid quenching or where aqueous corrosive contaminants are present.

Benefits

  • High temperature resistance.
  • Excellent resistance to oxidation under mildly cyclic conditions.
  • Good resistance to sulfidation and atmospheres where sulfur dioxide gas is encountered at elevated temperatures.
  • Good resistance to thermal fatigue.
  • Excellent toughness to cryogenic temperatures of -450°F.
  • Low magnetic permeability.
  • Good ductility and weldability.

Applications

  • Thermal processing and high temperature furnaces rely on 310 screws for their high temperature and oxidation resistance in minor cyclic conditions.
  • 310SS screws are commonly used in the petrochemical industry for their ability to provide resistance to moderately carburizing atmospheres.
  • The high temperature properties of 310 screws make them ideal for ore processing, steel plants, power generation, and sintering.
  • Cryogenic structures often use 310 stainless steel screws for their strength at -450°F and low magnetic permeability.
