May i know why you need this calculation? if possible please detaile it for
the benifit of all members. probably the following would help you!

This formula is used for detecting cracking susceptibility of steels and is
valid only for certain range of steels

Where *P*H is the cracking susceptibility parameter, H is the concentration
of hydrogen (in parts per million), *R*f is the restraint stress (in
megapascals), and:

Good luck!
