low pressure vacuum carburizing furnace

What factors will affect the hardness of low pressure vacuum carburizing furnace?

In fact, many of the equipment used in some industries have strong professional performance, such as low-pressure vacuum carburizing furnace, which is believed to be a kind of equipment that many people have not touched. But what we need to know is that the use of low-pressure vacuum carburizing furnace has certain rules to follow, so what do you know will affect the hardness of low-pressure vacuum carburizing furnace?

After carburizing and quenching, the carbon content and hardness of carburized layer at different parts were tested at 930 C and 80 min. It can be seen that the mass fraction of carbon decreases with the increase of distance from the surface, while the hardness increases first and then decreases. Generally speaking, the carbon content in steel is the most important factor to determine the hardness of martensite after quenching. The higher the carbon content in martensite, the greater the hardness, which is the most important factor leading to hardening of steel after quenching. At the same time, according to the characteristics of martensitic transformation of steel, it can be seen that the martensite structure will not be completely obtained after quenching, and there will be retained austenite. With the increase of carbon content in steel, the content of retained austenite increases, which reduces the hardness of carburized layer. The superposition of the two factors results in the hardness increasing first and then decreasing with the decrease of carbon mass fraction.

No matter what type of equipment we use, we need to master its basic principles before we can use it more appropriately.
