MilwaukeeJon Posted December 29, 2019 Share Posted December 29, 2019 Is the grain structure of a mid to high carbon steel (5160, 8670, 1075,1084) slow cooled in vermiculite fairly close to that when it is air cooled or normalized? In other words, is slow cooling considered a kind of normalizing? Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted December 29, 2019 Share Posted December 29, 2019 the slow cooling is annealing, Just cycling from above critical to below is normalizing Quote Link to comment Share on other sites More sharing options...
MilwaukeeJon Posted December 29, 2019 Author Share Posted December 29, 2019 Thanks. Learning more about grain structure is fascinating and helpful. Didn’t normalize a 5160 herb chopper and had some really interesting lateral splits, looked like delaminations, when working a really thin scroll on the handle.

Steve Sells Posted December 31, 2019 Share Posted December 31, 2019 yes annealing results in large grain Quote Link to comment Share on other sites More sharing options...
