Hi everyone
Can anyone tell me the minimum hardness for carbon steel >>>pipe A106 Gr.B NACE MR0175 ? because in 15156 just give us the maximum limit (22HRC) . Also what is the minimum requirements for NACE MR0175 from the side of chemical composition and other mechanical properties . thanks alot for everyone

If the material have cold strain equivalent to 15 % or les, provided the hardness in the strained area does not exceed 190 HBW, this is another consideration to take into account

Hardness min

Must be according to ASTM A106 gr B. But we estimate the value of hardness according to your effort to stress & ASTM 370. this could be estimate the hardness according to Tensile Strength min (60 Ksi) Table 3 Approximate Hardness 123 HB min. The min hardness value is not a requirement but it is a reference value.
