I think we can get away with alot more but im new to this material and am still young in my machining experience. What makes 4140 steel a good tool steel?What makes 4140 steel a good tool steel?One of the reasons why 4140 qualifies to be tool steel is the high content of chromium and carbon. The higher the chromium content the better. These two elements are responsible for giving this steel some extra level of hardness. The presence of molybdenum also tends to increase the corrosion resistance of this steel.Handbook Everything You Should Know About 4140 Steel What should the cooling rate be for 4140 welding?What should the cooling rate be for 4140 welding?Welding of 4140 in whatever condition should always be carried out using low hydrogen electrodes - please consult your welding consumables supplier.
