Dear all,
We received one 40" elbow (ASME 16.9) ASTM A 860 material having so much pitting on full external surface. Which standard we can refer for the acceptance criteria?
I referred in ASTM A 860, its talks about only depth of surface discontinuity(5% of the nominal thickness), there is no detail about the area of the pitting allowance.
Please help me on this issue. Very urgent
Regards,
Gulam Kader
