What is 310 and 310S Stainless Steel?

Description of 310 / 310S 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 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). When heated between 1202–1742°F (650–950°C) the alloy is subject to sigma phase precipitation. A solution annealing treatment at 2012–2102°F (1100–1150°C). Grade 310 (UNS S31000) and its various subgrades combine excellent high temperature properties with good ductility and weldability.

Grade 310S (UNS S31008) is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered “high temperature” service. The lower carbon content of 310S does reduce its high temperature strength compared to 310H. 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.

What is the Difference Between Stainless Steel 310 and 310S?

Types 310 Stainless Steel and 310S are typically used for elevated temperature applications. Their high nickel and chromium contents impart excellent elevated temperature strength and resistance to oxidation compared to Type 304 SS.

Stainless Steel 310S was designed to be the low carbon version (i.e. of 0.08%) of SS 310, a medium carbon stainless steel (which is 0.25%). 310S has many of the same characteristics and applications as 310, such as the ability to withstand high temperatures, resistance to oxidation and corrosion, and machinability similar to that of Type 304.
Composed of 20% nickel and 25% chromium, 310S is efficient in reducing environments such as those that contain sulfur. Combined with its low carbon content, the metal is also effective at resisting embrittlement. The metal is commonly utilized in extreme conditions, such as furnace manufacturing and heat treating equipment. While both hot and work practices can be applied, cold working is not commonly done on Stainless Steel 310S; however, it is the only way to work harden the metal. This resistance to cold temperatures is useful in cryogenic environments, as 310S is incredibly tough. However, it can be subject to thermal shock and therefore should be treated and hot-worked with care.

In ASTM 310S, The S stands for the special treatment of the ASTM 310 stainless steel, mechanical properties superior to ASTM 310 stainless steel, therefore, ASTM 310S stainless steel temperature is higher than the ASTM 310 stainless steel.

Properties and Processing Characteristics of Stainless Steel 310 / 310S

Alloy 310S, like 309S, is best known for high temperature service. Both alloys work well up to 2000 °F, especially if oxidation resistance is required. 309 and 310S are the premier high temperature performers among the common stainless grades available from our stock. High nickel and chromium content and a coarse grain structure result in:

  • Improved resistance to cyclic oxidation
  • Increased resistance to sulfidation
  • Better high temperature strength
  • Improved resistance to inter granular corrosion

310S stainless steel provides superior corrosion resistance properties against carburization, oxidation and other conditions. It is fabricated to offer excellent performance in the elevated temperature conditions on the industrial level that need high resistance to carburization and thermal cycling corrosion. It shows austenitic nature in the whole temperatures and doesn’t show embrittlement.The excellent strength and resistance to high temperature oxidation properties are purposeful in the commercial incinerators, kilns and food processing equipments. 

Processing Characteristics of 310S Stainless Steel:-

Speaking of the processing characteristics of the 310s stainless steel plate, first of all, we actually need to do this, then the hot processing will be divided into three types: point heating, linear heating, and triangular heating. And the point heating in the 310s stainless steel plate is mainly used to correct the uneven deformation of the sheet. Under normal circumstances, the larger the thickness of the 310s stainless steel plate, the larger the deformation will appear. The more the reinforcement, the larger the diameter, the smaller the distance will appear. For the linear heating of 310s stainless steel plate, there will be three basic forms at this time. The main ones will include linear, curved, and 310s stainless steel plate loop heating. When applying in detail, you should pay attention to the selection as appropriate. When the triangle is heated, it will first be used for the bending deformation of the pay steel beam and structural planning.

The 310s stainless steel plate thermal processing method will also be called flame rectification. In this method, the temperature of the flame is used to heat some of the 310s stainless steel plate, which is why it is cooling. Some new changes have occurred in the fire, and then it is enough to offset the old deformation and reach the purpose of correction.
When the 310s stainless steel plate is subjected to hot working, it is necessary to pay attention to the accurate selection of the heating direction at this time, and the temperature and the cooling time can also obtain a relatively good correction effect to a large extent. The higher the heating temperature, the more robust the 310s hot working correction is, the lower the heating temperature is. Generally speaking, it should be controlled to be between 1200-1600 °C. And when the 310s stainless steel plate is actually processed, it should be noted that it can not exceed 1900 ° C, the hot processing method of the 310s stainless steel plate, often using the heating of the gas welding torch. In this case, the thermal processing method is also used for the 310s stainless steel plate planning and some general low alloy steel planning.

Fabrication Data of 310 / 310S

Alloy 310 can be easily welded and processed by standard shop fabrication practices.
1. 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.
2. 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.
3. Welding
Alloy 310 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.

Corrosion Resistance

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:-

i.) Oxidizing conditions (max sulfur content–2 g/m3)
1922°F (1050°C) continuous service
2012°F (1100°C) peak temperature

ii.) Oxidizing conditions (max sulfur greater than 2 g/m3)
1742°F (950°C) maximum temperature

iii.) Low oxygen atmosphere (max sulfur content–2 g/m3)
1832°F (1000°C) maximum temperature

iv.) 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.
