310 Stainless Steel Seamless Pipes & Tubes

 

The 310 pipe grade is an austenitic alloy that is widely used in high pressure and temperature systems. The Stainless Steel 310 Pipe is manufactured with a high chemical composition of chromium and nickel. These pipes are designed to exist in highly corrosion-inducing environments and in different oxidizing media. A Stainless Steel 310 tube has outstanding resistance against pitting and cracking due to acids. These tubes can be availed in sizes between 6.35mm OD to 101.6mm OD. They are designed with hardness up to 217HB. The ASTM A312 TP310 Seamless Pipe possesses superior strength and mechanical properties. These pipes exhibit a minimum tensile strength of 515Mpa and a minimum yield strength of 205Mpa. They can be elongated by a minimum of 40 percent. Stainless Steel 310 Welded Pipe is a cost-effective pipe, which is produced by welding pieces of steel. These pipes are highly reliable and can provide a long service life. The UNS S31008 Stainless Steel Welded Pipe can be availed in thicknesses ranging between 0.3mm to 50mm. These pipes come in schedules between SCH 5 to SCH 160.

Applications of Grade 310 Stainless Steel


The steel is common throughout industry particularly in food processing as the material is not susceptible to corrosion from acids found in common foodstuffs. As a consequence, such steel is ideal for items such as sinks, work surfaces, preparation areas and refrigerators. It is also a perfect material for use in the pharmaceutical industry for environments such as clean rooms.

Grade 310 can also be found in heat exchangers, chemical containers, pipelines and throughout the brewing industry. It can be used as a fabricated material where high temperature petroleum gases or steam production gases are stored such as pressure vessels. It can even be found extensively in the construction industry where the material is used for cosmetic purposes such as building fascias.

310 plate and pipes have similar properties and in certain cases are stocked with Dual Certification, where it is concluded that each item has properties and a composition which comply with both steel types. Grade 310H cannot be included in this equation due to the steel's higher carbon content which is intended for use in elevated temperature applications.

310 Stainless Steel Pipes and Tubes Corrosion Resistance

Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 600C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 600C.


310 Stainless Steel Pipes and Tubes Heat Resistance

Good oxidation resistance in intermittent service to 8700C and in continuous service to 9250C. Continuous use of 310 in the 425-8600C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 310 is more resistant to carbide precipitation and can be heated into the above temperature range.

Grade 310H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 5000C and up to about 8000C. 310H will become sensitised in the temperature range of 425-8600C; this is not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.

310 Stainless Steel Pipes and Tubes Heat Treatment

Solution Treatment (Annealing) - Heat to 1010-11200C and cool rapidly. These grades cannot be hardened by thermaltreatment.
