Phil Ullrich Posted November 3, 2013 Share Posted November 3, 2013 I'm planning a blade that includes steel bolster/guard and butt cap. Considering brown patina on blade and fittings. I've browned steel with casey birch chemicals before, which involves heating the steel over 200 f and then brushing on the solution. Steel needs to be hot enough to sizzle the solution when applied, which I think is over 200f. Would heating the blade in this fashion spoil the heat treat? At what temperature would the heat treatment be spoiled? Off the top of my head I was thinking 400+ so the browning procedure should be safe, but correct me if I am wrong, please. I have always thought that one man of tolerable abilities may work great changes, and accomplish great affairs among mankind, if he first forms a good plan.... - Benjamin Franklin Link to comment Share on other sites More sharing options...
