Chemical heat treatment is to heat the workpiece containing carbon, nitrogen and other alloy elements in the medium (gas, liquid, solid) for a long time, so that the surface of the workpiece to form carbon, nitrogen, boron, chromium and other elements. After infiltration, some other heat treatment processes, such as quenching and tempering, are sometimes needed. The main chemical heat treatment is carburizing, nitriding and metallization.
It is precisely because of the emergence of seamless steel pipe that these high-pressure gas and liquid transportation problems have been solved, so that people can really make life so fast and convenient. Many factories have expanded the scale of production, and seamless steel tubes, like factories, have been used for high transportation.
