I need to use this knife to do the work. The material is QT450-10. When the tool is made, the first step is to process and reheat the required hardness without welding the blade, then weld the blade and reprocess.
My suggestion is high frequency quenching or mesh belt furnace quenchingI don't know the size of your work here. If it's over 50, then you will not be able to do it later
You should use the 40Cr to do the carrier, alloy blades. Actually come up with these heat treatments to sweat! How 40CR heat treatment can do directly tools?If you do the words, and it. Hardness is based on the condition of your knife, and 32-38HRC shouldn't be a big problem
