 ASTM A105

Standard Specification for Carbon Steel Forgings for Piping Applications

1. Scope
1.1 This specification covers forged carbon steel piping components for ambient- and higher-temperature service in pressure systems. Included are flanges, fittings, Valves, and similar parts ordered either to dimensions specified by the purchaser or to dimensional standards such as the MSS, ASME, and API specifications referenced in Section. Forgings made to this specification are limited to a maximum weight of 10000 lb [4540 kg]. Larger forgings may be ordered to Specification A 266/A 266M. Tubesheets and hollow cylindrical forgings for pressure vessel shells are not included within the scope of this specification. Although this specification covers some piping components machined from rolled bar and seamless tubular products (see), it does not cover raw material produced in these product forms.

ASTM A105N 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. ... The normalizing heat treatment will ensure the A105N steel has superior properties than the A105 steel.
