API 6A 60K material?

[gustorf]

Can anybody help me with the selection of valve body material in accordance with API 6A 60K? If possible with a european equivalent?
Thanks in advance.

Check ASTM A 694 F 60. Specify Impact test requirement (ASTM A 694 F 60 does not call for Impact test) based on your temperature classification (If it is P then you have to go for impact test at -29.

European equivalent not known.

6A 60ksi body will typically be 4130, 8630 or F22. SMTS is 85ksi and A694F60 only goes to 75ksi SMTS. None the less, 10K pipeline flanges are typically made to 6A out of A696 F60. Beware of the issue regarding gasket hardness vs groove hardness.
