What is the difference between ASTM A105 and A105N ？
A105N is the A105 material with Normalized.
A105 Flange Heat Treatment
Heat treatment is not a mandatory requirement except for flanges above Class 300, flanges of special design where the design pressure or design temperature are not known and for items over 4” NPS and above Class 300. When heat treatment is required, annealing, normalizing, normalize and temper, normalize and quench and tempering shall be the applied methods.
A105 Flange Hardness requirement NACE MR0175
A105 Flange should be with a Brinell hardness not exceed than 187 according to NACE MR0175
