Product Description

1: Brief Introduction Of 310/310S/310H stainless steel  
Alloy 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant
applications. The alloy resists oxidation up to 2010oF (1100oC) 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 -450oF (-268oC). When heated between 1202 - 1742oF (650 - 950oC) the alloy is
subject to sigma phase precipitation. A solution annealing treatment at 2012 - 2102oF (1100 - 1150oC) will restore a degree
of toughness.
310S (UNS S31008) is the low carbon version of the alloy. It is utilized for ease of fabrication. 310H (UNS S31009) is a high
carbon modification developed for enhanced creep resistance. In most instances the grain size and carbon content of the
plate can meet both the 310S and 310H requirements.
Alloy 310 can be easily welded and processed by standard shop fabrication practices.
Wet Corrosion:
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.
