ADEPT TECHNOLOGY Alloy 310 austenitic stainless steel

DESCRIPTION

Alloy 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. The alloy resists oxidation up to 2010°F (1100°C) under mildly cyclic conditions. Because of its high chromium and moderate nickel content, Alloy 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres. The more severe carburizing atmospheres of thermal process equipment usually require nickel alloys such as 330 (UNS N08330). Alloy 310 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. Alloy 310 also finds usage in cryogenic applications with low magnetic permeability and toughness down to -450°F (-268°C).

Applications 

• Cryogenic Components 

• Food Processing 

• Furnaces—burners, doors, fans, piping and recuperators 

• Fluidized Bed Furnaces—coal combustors, grids, piping, wind boxes 

• Ore Processing/Steel Plants—smelter and steel melting equipment, continuous casting equipment 

• Petroleum Refining—catalytic recovery systems, flares, recuperators, tube hangers 

• Power Generation—coal gasifier internals, pulverized coal burners, tube hangers 

• Sintering/Cement Plants—burners, burner shields, feeding and discharging systems, wind boxes 

• Thermal Processing—annealing covers and boxes, burner grids, doors, fans, muffles and retorts, recuperators, walking beams

Fabrication Data

Alloy 310 can be easily welded and processed by standard shop fabrication practices.

Hot forming

Heat uniformly at 1742–2192°F (950–1200°C). After hot forming a final anneal at 1832–2101°F (1000–1150°C) followed by rapid quenching is recommended.

Cold forming

The alloy is quite ductile and forms in a manner very similar to 316. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.

Welding

Alloy 310 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.
