310 Stainless Steel Sheet
310 stainless steel sheet/plate, 310S stainless steel sheet/plate, and 310H stainless steel sheet/plate is austenitic stainless steel used in high-temperature applications. It is used in temperatures up to 2,100℉ in continuous service. This grade contains 25% chromium and 20% nickel, making it highly resistant to oxidation and corrosion. 310S stainless steel is the lower carbon version of 310 plate which is less prone to embrittlement and sensitization in service. 310H stainless steel plate is the high carbon version.
310 Stainless Steel Sheet/Plate:
310 stainless steel sheet is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. The alloy resists oxidation up to 2010°F under mild cycling 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.
310S Stainless Steel Sheet/Plate:
310S stainless steel sheet is the low carbon version of the alloy. It is utilized for ease of fabrication.
310H Stainless Steel Sheet/Plate:
310H 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

310 stainless steel sheet/plate contains no more than 0.25% carbon while 310S contains at most 0.08% carbon. 310H stainless steel is comprised of between 0.04% and 0.1% carbon. 310, 310S and 310H stainless steel sheet/plate all contain 2.0% manganese, 0.045% phosphorous and 0.30% sulfur. 310 and 310S plate both contain 1.50% silicon while 310H stainless steel contains only 0.75% silicon. 310, 310S and 310H all contain between 24.0% and 26.0% chromium and between 19.0% and 22.0% nickel.
The internationally recognized crossover thickness between what is referred to as sheet and plate is 5.0mm. This is specified in ASTM A480M. Therefore, sheet is thickness less than 5.0mm and plate is 5.0mm and over.

Differences Between Hot Rolled and Cold Rolled:
Cold rolled stainless steel sheet has more accurate dimensional tolerances than that of hot rolled. Unless taking subsequent pickling or descaling treatment, hot rolled stainless steel sheet comes with a rough grey finish while cold rolled has a shinny whitish surface finish. From an economic view, cold rolled stainless steels are more expensive than hot rolled ones. Hot rolled has better ductility and malleability while cold rolled is harder and has more strength.
These grades of stainless steel sheet/plate have some very important and unique mechanical properties due to their composition. To begin, these grades all have a minimum tensile strength of 75 ksi and at 0.2%. 310, 310S and 310H all have a minimum yield strength of 30 ksi and an elongation of 40%. On the Brinell hardness scale they all have a hardness of 217, and on the Rockwell B scale, they have a hardness of 95.
These grades of stainless steel sheet/plate have a density of 0.285 lb/in^3 and a specific heat of 0.12 BTU/lb between 32℉ and 212℉. The electrical resistivity of 310, 310S and 310H is 30.7 Microhm-in at 68℉. These grades of plate also hav a module of elasticity of 28.5 x 10^6 psi. The melting range of these grades is between 2470℉ and 2555℉. These grades of stainless steel also have a thermal conductivity of 8.0 BTU/hr/ft^2/ft/℉.
Applications for these 310 grades of Stainless Steel Sheet/Plate includes the production of cryogenic components as well as use in furnaces, specifically in the construction of burner, recuperations, doors, fans, and piping. Because these grades of stainless steel can withstand very hot temperatures, it is also commonly used in the food processing industry along with in the chemical and pharmaceutical industries. These grades of stainless steel plate can withstand very high temperatures, thus making it useful to a wide range of industries.
