We have a partial specification of cast iron BLS21??? and are trying to establish the density of the material for dynamic balance correction purposes.

Density of Iron (#/in3)= 517-13.95*%C -5.67*%Si-4.43*%P
This formula is per H.T. Angus published in his book "Cast Irons Physical and Engineering Properties"
