Warren Nakkela Posted January 1, 2009 Share Posted January 1, 2009 Blessings for the coming year, This about knife blade steels. Suppose that you procured some austenitic 12% manganese steel and laminated these together with a core of, say D2 as a cutting edge. Since quenching manganese steel does not cause hardening but rather toughen the steel, would this result in toughness with a hard core? This likely has been tried as have been most things.

Steve Sells Posted January 1, 2009 Share Posted January 1, 2009 I am not sure there is a steel with 12% Mn. but a sanmai as you propose can and is made with mild outer portions. Quote Link to comment Share on other sites More sharing options...
Warren Nakkela Posted January 1, 2009 Author Share Posted January 1, 2009 There sure is. If manganese is, say around 4% it causes the steel to be brittle but around 12% the steel becomes austinetic (like stainless) and is true manganese steel. It is used where extreme toughness is required. Like in boom point sheaves, for example Warren Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted January 1, 2009 Share Posted January 1, 2009 cool give it a try and report back sounds like fun ! Quote Link to comment Share on other sites More sharing options...
