Hi all

Can anyone tell me what is the "Grade" in the ASME B31.3 stand for? And tell me how to find out the explanation for this code e.g. 45, 50, 55, B.........

Any website or reference books

Thank you so much

Frederick Chan
 
The grade can be found in the applicable ASTM material standard.
E.g. A 106 Grade B. Look in the ASTM A 106 and you will find different Grades.
