The difference is after heat treatment. The main role of Cr in heat treatment is to improve the hardenability of steel. Due to the improvement of hardenability, the strength, hardness, impact toughness and other mechanical properties of 40Cr after quenching (or tempering) treatment are also significantly higher than those of 45 steel. 5.What is the hardness of 40Cr material?

In a general sense, quenching is a form of heat treatment performed on various types of steel. Although there is a special heat treatment cycle for each steel type, the thermal refining heat treatment process generally involves heating carbon steel for mechanical structures with a greater than 0.3% carbon content together with alloy steel until Heat Treatment of Steels & Metals Bright Hub EngineeringHeat treatment of steels is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc.
Oct 11, 2010· Heat treatment of metal is done by raising the temperature to a point where there is a change in the crystal structure of the metal (an expert can look under a microscope and see what has been done). But the actual crystal structure is on a molecular level. Depending on what you are trying to do, the metal is either quenched to prevent the CN102071291A Hardening and tempering method for alloy The invention discloses a hardening and tempering method for an alloy steel 40Cr steel plate.
