Ductile Iron
Overview
Royal Metals Ltd. is proud to present Dura-Bar ductile iron; a cost-saving alternative to low-medium carbon steels and has similar strengths with excellent free machining properties. The nodular graphite provides the same free machining benefits as lead, without creating the machining and waste disposal problems. 65-45-12, 80-55-06, 100-70-03 and 60-40-18 will conform to ASTM A536, with the primary difference being the high nodule count and fine grain size inherent to the Dura-Bar continuous casting process. SSDI is similar to ISO 1083/JS/500-10. The different grades are produced by controlling the matrix structure around the graphite nodules.
