What is ASTM A105N flanges? Is this your question? If yes, then this article will entail everything about flanges and its specification in detail. These are steel flanges that are manufactured by A105N material, where "N" symbolizes the heat treatment to the steel. ASTM A105 is the one of the common forged steel material used for manufacturing flanges. After heat treatment normalization, this A105 steel easily removes internal stresses caused due to forming, casting or forging. This heat treatment ensures steels superior properties. These flanges are used for high temperature and ambient services. They are hard and contain nickel content. They are used in various applications like a boiler, petroleum industry, shipbuilding and electric industry.

Product specification
There are various types of ASTM A105N flanges, available such as WN welding neck, SO slip-on, TH threaded, LF lapped stub end, orifice flange, and long welding neck. The material used for making these flanges is ASTM A105 steel; these flanges meet both international and national standards like ASME, ANSI B16.5, and MSS SP44. They are manufactured and well coated with black paint, oil coating to prevent it from rusting. You can easily use them at different pressure levels such as CLASS 150, CLASS 600 and CLASS 2500. Beside those ASME and ANSI standards, these flanges are manufactured in other standards also.

ASTM A105N flanges are tested and inspected by inspection agencies. Customers are provided the proper mill test certificate and packing list. They are packed in wooden cases, plywood boxes or seaworthy packages to prevent flanges from any kind of damages.
