What tests should be performed after heat treatment?

What tests should be performed after heat treatment?

Hardness 1) All heat treated parts should undergo hardness inspection or spot check according to the requirements of the drawing and process regulations. 2) Calibrate the hardness tester with a standard block and confirm before testing the hardness.

Throughout my life, I have been misled by these heat treatment issues!

Throughout my life, I have been misled by these heat treatment issues!

Firstly, it is believed that the workpiece is carburized in quenching oil; Secondly, it is believed that the graphite component in the heating chamber caused carburization. In fact, in many cases, it is not these two reasons, but the cleanliness of the heating chamber is not high. There is a large amount of quenching oil in the workpiece entering and exiting the furnace, the material basket is polluted, and the feeding car enters and exits the heating chamber, remaining on the cold wall of the heating chamber. During heating

Heat treatment equipment has many advantages such as fast heating speed, energy saving, non oxidation and decarbonization, no environmental pollution, and high production efficiency. These advantages are widely recognized by heat treatment workers, and therefore have developed rapidly in the past decade.

Carbon steel, also known as carbon steel, has a carbon content ω Iron carbon alloys with c less than 2%. Carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus in addition to carbon.

Forging knowledge is too summary, recommended collection

Forging knowledge is too summary, recommended collection

Forging is one of the two components of forging (forging and stamping), which uses forging machinery to exert pressure on metal blank and make it produce plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. Through forging, defects such as loose as cast can be eliminated in the process of metal smelting, and the microstructure can be optimized. At the same time, the mechanical properties of forgings are generally better than those of castings of the same materials because the complete metal streamline is preserved.
