Four electric induction melt furnaces supply 200 tons of melt a week, per shift. Types and grades of iron and steel that can be produced include the following:

Gray Irons     ASTM A48     Classes 20, 30, 35,     40, 50, and 60     SAE J431     Grades 2500, 3000,     3500, & 4000 Ductile Irons     ASTM A536     Classes 60-40-18 (D6H),     65-45-12 (D6),     80-55-06 (D8),     100-70-03 (D10)     SAE J434C     Grades D-4018, D-4512,     D-5506, D-7003

Ni-Resist Irons     ASTM A436     Classes 1 thru 6 (all) Ductile Ni-Resist Irons     ASTM A439     Classes D2, D2B, D2C, D3,     D3A, D4, D5, D5B White Irons     ASTM A532-80     Classes I thru III (all) Ni-Hard Irons     ASTM A532     Types 1 thru 4 (all)

Melt composition is continually checked on the melt deck using thermal analysis. A ten element spectrometer analyzes each heat to assure the proper composition of all gray and ductile iron.
