How is the temperature of a quenching medium controlled?How is the temperature of a quenching medium controlled?The action will continue with heat flowing from the centre of the workpiece to the surface until both the workpiece and the quenching medium attain the name temperature. The rate at which the heat can be abstracted from the steel is controlled by the thermal conductivity of steel and the specific heat of the quenching medium.Quenching of Steel Purpose and Mechanism Industries 37cr4 quenching and tempering steel(plate) When do you use high temperature tempering on carbon steel?When do you use high temperature tempering on carbon steel?So the general carbon steel and carbon alloy steel is often take high temperature tempering after quenching.

Annealing. After heating the steel to a temperature of Ac3 + 30 -50 degrees or Ac1 + 30 50 Normalizing. Heat the steel to 30 50 degrees above Ac3 or Accm, after soaking, cool it at a Quenching. The steel piece is heated to a temperature above the phase transition temperature Tempering. The quenched steel parts are heated from the beginning to a temperature below Ac1, Quenching and tempering. After quenching, high temperature tempering is called quenching and Aging. Heat the steel to 80 200 degrees, keep it for 5 20 hours or longer, then take it out of the Cold treatment. The quenched steel parts are cooled in a low-temperature medium (such as dry Flame-heated surface quenching. The flame incinerated with oxygen-acetylene mixed gas is Induction heating surface quenching. Put the steel parts into the inductor, make the surface of the Carburizing. Put the steel parts in the carburizing medium, heat it to 900-950 degrees and keep it (plate) 215mm thick, Quenching and Tempering, high tensile steel 37cr4 quenching and tempering steel(steel) with the steel manufacture domestically, Wugang starts in 2008 to research and develop 140mm thick quenching and tempering high tensile steel A514GrQ, the lasted 10 months obtain successfully, broke our country ocean platform essential spot to rely on the import for a long time with the high tensile steel

Place the steel into a heat treat oven or forge and raise the temperature to between 1,550 degrees Fahrenheit and 1,650 degrees Fahrenheit. Allow the steel to remain in the oven for a "soak" time of at least 30 minutes. Allow more soak time for more massive pieces of steel.

Steel is strong to begin with, but sometimes its necessary to make it even stronger. One of the common treatments to achieve this is quenching and tempering. This is a process that strengthens and hardens iron-based alloys by heating, rapidly cooling, and reheating. When steel is heated above a certain point, the grain (molecular) structures are changed.
