What is ASTM A105N flange?
ASTM A105N steel flange means the steel flange made by A105N material.ASTM 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.
After normalization,A105 steel will remove the internal stresses caused by casting,forming or forging.The normalizing heat treatment will ensure the A105N steel has superior properties than the A105 steel.If a inquiry specifically indicates they need A105N,then it is necessary to use A105N material.(ASTM A105 steel flange)
