Ductile Iron Conference: Marketing as Important as Practice (continued from page 61)
metalcasting facility needs to be in the business of growing the pie for what it is you produce,” Muratore said. He went on to state that attendees needed to take into
careful consideration ductile iron’s position not only in North America, but the world. Looking back 45 years, gray iron led overwhelmingly in terms of tons of castings shipped (74%), steel was second (10%), malleable iron third (6%), other met- als fourth (5%), aluminum fifth (3%) and ductile iron sixth (2%). In 2009, 33% of all castings shipped were ductile iron. Fred Linebarger, Miller and Co., Rosemont, Ill., also pre-
sented at the conference, going into detail on ductile iron metallurgy and processing, while also discussing ductile iron specifications, melting and charge materials, inoculation and treatments, filtration and gating systems, and quality assurance. Linebarger said that while it is common practice to put a
filter directly under the down sprue, it is not recommended. The combination of the head pressure and force of the metal at the sprue can overheat the filter and cause it to distort and break, potentially drawing filter residue into the gating stream and casting cavity. It is better practice to put the filter into the gating system in a location downstream from the sprue. The presenters also discussed special applications of ductile
iron, including austempered, high silicon molybdenum and compacted graphite iron.
MC AFS Updates MSDS Forms AFS has finished updating all Material Safety Data Sheets
(MSDS) for iron, steel, aluminum, copper and magnesium- based casting alloys. The updated MSDS forms, with a current date of October 2010, can help metalcasters meet their ISO certification and Canadian three-year review requirements. Additionally, the alloy and hazard information has been
updated to ensure that OSHA and American Conference of Governmental Industrial Hygienists information is current. All MSDS remain in the 16-part ANSI format.
