How To Heat Treat 4140 Alloy Steel. But it should be tempered for any heavy use. The elements that have the strongest effect are C Mn Mo and Cr for 4140. 1 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering crown and so on. Heat the steel to 1675 degrees Fahrenheit in a heat treat furnace or forge and hold it at that temperature for.
Nitriding the part will give me the result that I am looking for using 4140 steel to a depth of 0010 0015 without the extra machining involved. Tempering reheating after quenching will achieve the desired hardness range. The elements that have the strongest effect are C Mn Mo and Cr for 4140. It all makes sense now. The metal is brought up to 1200 F slowly and held there for 10-15 minutes. One point that was brought up was that Nitriding will provide wear resistance and not impact resistance.
Be sure to use safety gear when doing.
4 the area denoted as austenite is actually an area within which iron can retain much dissolved carbon. But it should be tempered for any heavy use. The elements that have the strongest effect are C Mn Mo and Cr for 4140. 1 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering crown and so on.
