After heating, heat preservation and cooling, the performance of the metal will change differently, and the performance of the same flange pipe fittings will also be different after heating, such as the superior performance of stainless steel flange pipe fittings obtained by heating and cooling ...
Heat treatment refers to a metal hot working process in which materials are heated, insulated and cooled in the solid state to obtain the expected microstructure and properties.
Machine for heat treatment
There are four basic processes for overall heat treatment of iron and steel: annealing, nor ...
The heat treatment of pipe normally have five ways as below:
1.Quenching+high temperature tempering
The steel pipe is heated to the quenching temperature, so that the internal structure of pipe can be transformed to austenite, then cooled faster than the cirtical quenching speed, so that the int ...
After the metal is heated, insulated and cooled, the properties of the metal will change differently. After heating, the performance of the same flange pipe fitting will also be different. For example, stainless steel flanges have superior performance. The heating and cooling effects of pipe fit ...
