Alloy 310S

An austenitic chromium-nickel grade, Alloy 310S (1.4845) displays excellent oxidation resistance up to 1094°C

Alloy 310S (1.4845) displays excellent resistance to oxidation under mildly cyclic conditions. As a result of its high chromium and nickel content, Alloy 310S has good resistance to sulphidation and other forms of hot corrosion.

Perfect for applications in the Thermal Processing industry

Alloy 310S can be used in a variety of applications, here are just a few examples:

  • Flare tips
  • Fluidized bed coal combustors
  • Radiant tubes
  • Tube hangers for petroleum refining and steam boilers
  • Coal gasifier internal components
  • Thermowells and refractory anchor bolts
  • Burners, combustion chambers
  • Retorts, muffles, annealing covers
  • Cryogenic structures

About Alloy 310S

Alloy 310S is widely used in moderately carburizing atmospheres such as those encountered in petrochemical environments. The more severely carburizing atmospheres of industrial heat treating furnaces require RA330® or RA333®. Alloy 310S is not suggested for the severe thermal shock of repeated liquid quenching.

The grain size and carbon content meets both 310S and 310H requirements. Alloy 310S is often used at cryogenic temperatures, with excellent toughness and low magnetic permeability. Alloy 310S has good machinability and is readily fabricated.

FAQs & Resources

Stainless steel is the generic name of different grades of steels (containing low carbon and iron), used primarily because of their corrosion resistance. All stainless steels share a minimum percentage of 10.5% chromium element. Chromium (Cr), usually a deciding factor, nickel and molybdenum are commonly added to steels to improve their corrosion resistant and make them ‘stainless’. Most of the stainless steel grades will have a UNS number that start off with letter ‘S’ such as UNS S32100 (Alloy 321) and UNS S31008/S31009 (Alloy 310/310S).

Alloy 321, 316Ti, 309, 310S, 800 H/AT, 253 MA®, RA330 ®, RA333®, 600, 601, 602 CA® are generally referred to as heat resisting alloys and used in various high temperature applications.
