This process is often used for knife making, by heating only the edge of a previously quenched and tempered blade. When edge turns the proper color temperature, it is quenched, hardening only the edge, but leaving most of the rest of the blade at the lower hardness. The knife is then tempered again to produce the final differential hardness. [16]
This is the most common state for finished articles such as tools and machine parts. In contrast, the same steel composition in annealed state is softer, as required for forming and machining. Depending on the temperature and composition of the steel, it can be hardened or softened. To make steel harder, it must be heated to very high temperatures.
1095, a popular high-carbon steel for knives; it is harder but more brittle than lower-carbon steels such as 1055, 1060, 1070, and 1080. It has a carbon content of 0.90-1.03% [7] Many older pocket knives and kitchen knives were made of 1095. With a good heat treat, the high carbon 1095 and O-1 tool steels can make excellent knives.
To harden by quenching, a metal (usually steel or cast iron) must be heated above the upper critical temperature (Steel: above 815~900 Degrees Celsius [23]) and then quickly cooled. Depending on the alloy and other considerations (such as concern for maximum hardness vs. cracking and distortion), cooling may be done with forced air or other ...
Knife sharpening is the process of making a knife or similar tool sharp by grinding against a hard, rough surface, typically a stone, [1] or a flexible surface with hard particles, such as sandpaper. Additionally, a leather razor strop , or strop, is often used to straighten and polish an edge.
Material hardening is required for many applications: Machine cutting tools (drill bits, taps, lathe tools) need be much harder than the material they are operating on in order to be effective. Knife blades – a high hardness blade keeps a sharp edge. Bearings – necessary to have a very hard surface that will withstand continued stresses.
Steel with a high carbon content will reach a much harder state than steel with a low carbon content. Likewise, tempering high-carbon steel to a certain temperature will produce steel that is considerably harder than low-carbon steel that is tempered at the same temperature. The amount of time held at the tempering temperature also has an effect.
Springs must be made of hardened steel. At this time, the processes for making steel produced an extremely variable product—quality was not ensured at the initial point of sale. Springs that had survived cracking through hard use over the rough roads of the time, had proven to be of a better quality steel.
