bridgtonblacksmith Posted December 5, 2005 Share Posted December 5, 2005 I need some help with a piece of 4340 that I have. I am interested in making some blacksmithing tools out of a 2-5/8" dia. bar of 4340. I am a little confused about the proper way to harden and temper this material. I would like to make a nice sledge hammer head and possibly some hardy tools. Have any of you ever worked with this type of steel and have some wisdom to share? Thanks, Paul Quote Link to comment Share on other sites More sharing options...
Glenn Posted December 5, 2005 Share Posted December 5, 2005 www.suppliersonline.com/propertypages/4340.asp There is a discuaaion on the Anvilfire-Guru's page on this type metal in the area of Dec 1, 2005. You may want to reference to that also. Quote Link to comment Share on other sites More sharing options...
