What is A105 steel flange?

　　A105N flange means the steel flange made by A105N material.A105N steel has no grade in the ASTM A105 standard,N means the heat treatment Normalization to the steel.

　　ASTM A105 is the most common forged carbon steel material for flanges,but it is not suitable in low temperature service,A105N steel is widely used as the flanges material in low temperature service and other critical application.

　　ASTM A105N forged steel flange is our regular flanges in our factory.This material is the based in the ASTM A105 with heat treatment normalization.After the heat treatment,the flanges have a better performance in mechanical property than normal forged steel ASTM A105 grade.ASTM A105N material commonly is used in ANSI/ASME/AWWA standard flanges.
