Variation of Impact Values by Heat Treatment Temperature to Prevent Brittle Fracture of Roll Shell Steel Suh, Chang-Min; Suh, Min-Soo; Cho, Hae-Yong;
This study involved a series of experiments, which included impact tests (drop weight & Charpy) and hardness tests under various heat treatment conditions, followed by fractography observations of Normal Roll Shell steel (NRS), Abnormal Roll Shell steel (ARS), and S25C steel, in order to analyze the cause of brittle fracture and damages in Roll Shell steel. The optimal tempering temperature was characterized for ARS and NRS.
