4140 steel for knives? Bushcraft USA Forums

Jan 19, 2012 · Blind Horse Knives used 4140 for a time before switching to the far superior O1. Not a favorite for most bladesmiths, but the steel does fine (yawn) if it is heat treated properly. I think Blind Horse finished theirs up in the mid-50's Rockwell (not much good once it gets too hard). An older BHK Bushbaby in 4140. 4140 steel forging, 4140 steel forging Suppliers and offers 6,255 4140 steel forging products. A wide variety of 4140 steel forging options are available to you, such as standard, surface treatment, and application.

The lower the finishing temperature from forging, the finer will be the grain size. How To Weld 4140 Steel WELDING ANSWERSAISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a

Philadelphia Forgings

Philadelphia Forgings provides the following grade of alloy steel forging:4130, 4140 , 4150. Alloy steels 4130, 4140, and 4150 are all chromium-molybdenum steels. The elements molybdenum and chromium are used to strengthen these materials. Forgings made from these metals are tough with high fatigue strengths. 4330, 4340, 8620, 8630, 9310.
