Stainless Steel 310 Sheet/Plates
Great Steel & Metals offers wide range of superior quality stainless steel 310 sheet/plates to all its valuable customers around the world. Stainless steel 310 alloy is austenitic steel in which the properties such as extremely high temperature are combined with good weldability and ductility. The high content of chromium and nickel in stainless steel 310 makes it an ideal choice for the applications that require superior strength in temperature, great resistance to oxidation and corrosion etc.
The stainless steel 310 sheet/ plates contain 20% nickel and 25% chromium that make them highly resistant to corrosion and oxidation. In service, the stainless steel 310 sheet/ plates are less prone to sensitization and embrittlement, offer low magnetic permeability and high toughness. These properties make stainless steel 310 sheet/plates extremely useful in number of applications such as radiant tubes, steam boilers, tube hangers for petroleum refining, components of coal gasifier, refractory anchor bolts, lead pots, cryogenic structures, food processing equipments, annealing covers, saggers, retorts, combustion chambers, burners, refractory anchor bolts, furnace parts, heat exchangers, fire box sheets etc.

Alloy 310 is not designed for service in wet corrosive environments. The high carbon content, which is present to enhance creep properties, has a detrimental effect on aqueous corrosion resistance. The alloy is prone to intergranular corrosion after long term exposure at high temperatures. However, due to its high chromium content (25%), Alloy 310 is more corrosion resistant than most heat resistant alloys.
High Temperature Corrosion
The high chromium (25%) and silicon (0.6%) content of Alloy 310 make it more resistant to high temperature corrosion in most in-service environments. Operating temperatures are listed below.
Oxidizing conditions (max sulfur content – 2 g/m3)
1922°F (1050°C) continuous service
2012°F (1100°C) peak temperature
Oxidizing conditions (max sulfur greater than 2 g/m3)
1742°F (950°C) maximum temperature
Low oxygen atmosphere (max sulfur content – 2 g/m3)
1832°F (1000°C) maximum temperature
Nitriding or carburizing atmospheres
1562 – 1742°F (850 – 950°C) maximum
The alloy does not perform as well as Alloy 600 (UNS N06600) or Alloy 800 (UNS N08800) in reducing, nitriding or carburizing atmospheres, but it does outperform most heat resistant stainless steels in these conditions.

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