are all seamless pipes made under ASTM A106GrB NACE compliant?
are all seamless pipes made under ASTM A106GrB NACE compliant?
(OP)
Please can somebody let me know if a pipe produced under ASTM A106 GrB is NACE compliant? i see NACE wants materials to have less then 1% nickel value whereas ASTM allows 0.4% and the max tensile strength is somewhere around 510MPA which corresponds to hardness well below HRC22 as allowed by NACE..Can somebody confirm this?

As for hardness i saw a number of MTR's for A106GrB material and all show tensile strength of about 490MPA with corresponds to a hardness level well below 100HRB of 22HRC.
Any comments on this?
