ASTM A182 310MoLN Flanges are made from the material 310MoLN, which is a super-austenitic stainless steel that offers exceptional toughness, corrosion resistance, and high-temperature strength. It contains molybdenum, nitrogen, and nickel which give it superior resistance to pitting and crevice corrosion in harsh environments.
The 310MoLN flange is available in various types such as slip-on, socket weld, blind, weld-neck, threaded and lap joint. It is a versatile flange that can be used in wide-ranging applications such as chemical and petrochemical processing, power generation, seawater desalination, and oil and gas industry.
The chemical composition of 310MoLN Flanges makes it an ideal choice for applications that require excellent resistance to corrosion in acidic or alkaline environments. It is also suitable for use in high-temperature applications. The flange is highly resistant to stress-corrosion cracking, which makes it particularly useful in environments where chloride stress corrosion cracking is a concern.

One of the main advantages of 310MoLN Flanges is their ability to withstand high temperatures and high pressure. This quality makes them ideal for use in high-temperature applications such as boilers, heat exchangers, and pressure vessels. They are also used as a component in high-pressure steam turbines where they provide reliable connections between the turbine and other components.
ASTM A182 is a standard for forged or rolled alloy-steel pipe flanges, forged fittings, and valves and parts for high-temperature service.
