What is SS310?

0 0 votes

SS310 is also called Grade 310. It is an alloy made from various metals. It is a high-temperature and corrosion-resistant stainless steel alloy. This alloy is a type of austenitic stainless steel. SS310 is a non-magnetic alloy. This alloy has a high amount of chromium and nickel content. According to online portals, it contains around 25% chromium and 20% nickel. Read on to know more about ss310 here:

SS 310 Chemical Composition

SS 310 is made from a mixture of carbon, silicon, manganese, phosphorous, sulfur, chromium, nickel, nitrogen, and iron. SS 310 chemical composition makes it very sturdy and heat resistant. It also makes the alloy corrosion-resistant. SS310 is used for a lot of reasons. It has a wide range of applications. It is used in fluidized bed combustors, kilns, radiant tubes, tube hangers, coal gasifier internal components, lead pots, food processing equipment, saggers, annealing covers, retorts, mufflers, burners and combustion chambers, thermowell, refractory anchor bolts, etc.

SS 310 Workability

SS 310 stainless steel is also called UNS 31000. Due to its high levels of chromium and a medium level of nickel, this alloy has good resistance to sulfidation. It also has good resistance to other types of hot corrosion. SS310 is quite popular and is used in moderately carburizing environments. It also has petrochemical applications. SS 310 or 310-grade stainless steel is a non-magnetic substance. It has non-corrosive properties, just like 304/304L.

Physical Properties of SS 310

SS 310 is forged and fabricated in temperatures ranging from 975°C to 1175°C. After forging, it is recommended for annealing to relieve all kinds of stresses of the forging process. According to portals, ss 310 is cold-formed by standard tools and methods. The machinability of Grade 310/310S is very similar to that of 304. It is susceptible to work hardening. However, it is normal to remove the work-hardening layer by using slow speed and heavy cuts via sharp tools and good lubrication. Powerful machinery and heavy tools are used for the same.

SS310 is also used in cryogenic applications. This is the case because this alloy has a low magnetic permeability. It is also tough down to -450 degrees Fahrenheit. When heated, this alloy can be found with sigma phase precipitation. According to online portals, an annealing treatment with a solution will restore its toughness to some degree.

SS 310 chemical composition makes it less susceptible to oxidation. It will resist oxidation at temperatures up to 2000 ̊F in dry air. This is due to the fact that SS 310 stainless steel is a high-temperature chromium-nickel austenitic stainless steel. It is also resistant to spalling.

One of the best properties of 310 stainless steel is that it is resistant to oxidation. This is in environments up to 1035°C and 1050°C. This grade of steel is also resistant to carburization and sulfidation. This is the case even when the maximum working temperature has to be reduced.


In conclusion, it can be stated that SS310 is one of the best alloys of iron and other substances. It is a combination of iron, sulfur, carbon, nickel, chromium, etc. It can be used in a number of things. It also has a number of applications. It is used in fluidised bed combustors. It is also used in Kilns and radiant tubes. SS 310 is also required in tube hangers for petroleum refining and steam boilers. 310 stainless steel can also be used in lead pots and thermowell. Refractory anchor bolts, burners and combustion chambers also use this alloy. This iron alloy is also used in retorts, muffles, annealing covers, saggers, etc. Thus, it can be said that SS 310 is quite a versatile alloy.
