Dura-Bar G1A Continuously Cast Gray Iron Bar Stock ASTM A48
Categories:	Metal; Ferrous Metal; Cast Iron; Alloy Cast Iron; Gray Cast Iron
Material Notes:	Dura-Bar G1A has Type D graphite in a predominantly ferrite matrix. This specification was originally developed for the glass mold industry where a fine grain structure and superior machining finish are needed. Dimensional growth due to repeated heating and cooling cycles is minimal due to the smaller graphite flake size and ferritic matrix structure. The microstructure will contain Type VII, type D, size 6-8, graphite as defined in ASTM A247. The matrix is predominantly ferrite. Chill carbides will be less than 5% in any field at 100x and will be well dispersed. G1A is not intended for hardening. The matrix structure may be softened slightly by heating to 1400°F (760°C) and furnace cooling to 400°F (205°C). Composition: Typical chemical composition and ranges, actual values depend on cross section size. Information provided by Dura-Bar.
