FLAKE GRAPHITE CAST IRON FOR LARGE-SIZED CASTING PRODUCT AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a large-sized casting product capable of having satisfactory strength and hardness in a gradual solidifying process such that a cooling time after casting exceeds ten hours.;SOLUTION: A flake graphite cast iron for a large-sized casting product contains a type-A graphite and has a high Mn-based basic composition containing 3.05 mass% or more of Mn. In the high Mn-based basic composition, an Mn/S abundance ratio of the Mn content to the S content is preferably in a range of 6 to 800.;COPYRIGHT: (C)2012,JPO&INPIT
