Tempering (metallurgy) - Wikipedia
Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.
How Quenching Hardens Steel in Metalworking
9/8/2019· As a result, quenched steel typically undergoes a tempering process. This involves reheating the metal to a temperature below a critical point, then allowing it to cool in the air. Typically, steel will be subsequently tempered in oil, salt, lead baths, or furnaces with air circulated by fans to restore some of the ductility (ability to withstand tensile stress) and toughness lost by

Metal spinning - Wikipedia
Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. Spinning can be performed by hand or by a CNC lathe. Metal spinning does not involve removal of material, as in conventional
DIY Annealing and Re Hardening Steel for Knife Making

How to Colour Steel With HEAT : 5 Steps (with Pictures) - …
The "turning blue" process has nothing to do with hardening of the steel, or its compression. It is caused by a layer of oxide that forms when the steel is heated. The thickness of the oxide is a function of how hot you heat the steel (The color is due to interference of light reflecting from the surface of the oxide coating, and light reflecting from the oxide-steel interface).
