STAINLESS 310 PROPERTIES
Stainless steel 310 is an austenitic steel developed for use in high temperature corrosion resistant applications. The steel resists oxidation up to 2010°F (1100°C) under mildly cyclic conditions. Because of its ratio of Chrome to Nickel content, this alloy is resistant to sulphidation and can also be used in moderately carburising atmospheres.
USES OF THE GRADED STEEL
Due to its heat resistant properties, it is often used in the following:
- Fluidised bed coal combustors, grids, piping & wind boxes
- Food processing equipment
- Radiant tubes
- Tube hangers for petroleum refining
- Steam boilers
- Flare tips
- Smelting & steel melting equipment
- Refractory anchor bolts
- Burners, combustion chambers & furnace doors
- Retorts, muffles, annealing covers & boxes
- Cryogenic structures
Even under mildly cyclic environments, it resists oxidation up to 2010oF (1100oC). Plus due to the 310s high chromium and moderate nickel content, plus it is good resistant to sulphidation and can be used in moderately carburising atmospheres.
Unlike the more severe carburising atmospheres which usually require nickel as part of the process; it can be used in slightly oxidising, nitriding, cementing and thermal cycling applications, however the maximum service temperature must be reduced.
It also finds usage in cryogenic applications with low magnetic permeability and toughness down to -450oF (-268oC). Plus when heated between 1202 – 1742oF (650 – 950oC) is subject to sigma phase precipitation. Therefore a solution annealing treatment at 2012 – 2102oF (1100 – 1150oC) will be needed to restore a good degree of toughness.
The alloy can also be easily welded and processed by standard shop fabrication practices.
