Stainless Steel Grade 310 is an austenitic stainless steel with a mild carbon content. It is suitable for use in high-temperature environments because of its resistance to heat, but it is not as strong at room temperature. It is more resistant to corrosion than other austenitic stainless steels and has excellent strength at high temperatures; however, it does not perform as well at very low temperatures.
Stainless Steel 310 Pipes are often used at cryogenic temperatures, with good corrosion resistance to increase high-temperature properties and withstand corrosive attacks. The temperature resistance of grade 310 is due to the high chromium and nickel content. The high chromium content also provides good resistance to oxidation and corrosion at high temperatures. These grades cannot be hardened by heat treatment, but can be hardened by cold work.
Applications:
The most common applications of these pipes are in refineries, power plants, petrochemical plants, and in industrial heat exchangers. The applications include:-
- Piping systems
- Heat exchanger components
- Gas burner parts
- Flare stacks
Stainless Steel 310 Pipes are available in various forms like SS 310 Seamless Pipes, Welded Pipes, ERW pipes, Fabricated Pipes etc.
Stainless Steel 310 Seamless Pipe is a solid solution carbon steel alloy with chromium and nickel content to form an alloy steel with excellent corrosion resistance and high strength. Alloy 310 welded stainless steel pipe is an austenitic chromium-nickel alloy with excellent oxidation resistance to carburizing and reducing environments. Stainless Steel UNS S31000 Round Pipe can be hardened by only cold working.
Fabrication of SS310 seamless pipes: Stainless steel 310 seamless pipes are fabricated through a process that includes the following steps:
Heavy work is done, then the pipes are forged at temperatures ranging from 975 to 1175 degrees Celsius.
A light finish is applied to the bottom of the range, and annealing is suggested to remove all tensions from the forging process.
The alloys may be easily cold produced using ordinary procedures and equipment.
Machinability of SS310 seamless pipes: 310 can be machined with the same tools and methods as 304. However, it is typical to remove the work-hardened layer using moderate speeds and heavy cuts, sharp tools, and excellent lubrication. Powerful machinery and hefty, stiff tools are required for this type of machining.
