Abstract :
The Fermilab Main Injector project is building 344 dipoles, for which over 7000 tons of steel are required. Budgetary and logistic constraints prevented purchasing all of the steel required prior to production. Run to run variations in the magnetic properties of the steel have produced variations in the excitation curves of the dipoles. The variations in the B(H) curves for the steel as a function of run number, and the excitation characteristics of the dipoles, are discussed
