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.

山东大鼎金属材料有限公司From a positive point of view, the market is still in weak integration. Price adjustment policies, as the weather warms, are slowly reviving the industry; if raw materials do not show too much volatility, it is difficult to fall again, because the market is less profitable and expected to be higher, so alloy tubes will be very strong after a tentative pull on the market.

Precision steel pipes are mainly used to produce seamless or welded products such as pneumatic or hydraulic components, such as cylinders or cylinders, because of their advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision and so on. SH, no cold bending deformation, flat and no crack. Precision steel pipe mainly produces 10, 20, 35, 45, 40 cr, 42CrMo grade precision seamless steel pipe can also be consulted and supplied.
At heating time (s) = KD, D is the thickness of the workpiece, mm, K as the coefficient, and the factory data. (3) cooling. Different cooling systems are used for different tissues. It is usually cooled in static air. If the workpiece is large, it can be cooled by blowing or fog. The length is usually也许正是因为这个原因，在过去相当长的时间，另一方面，虽然有关各方已提出了许多警告，产能过剩的钢铁行业，甚至进行产业结构调整，地方政府仍然回避了铁和ST通过“变为零”等政策的对策就是鳗鱼项目；同时，为了维护相关的钢铁产能对地方GDP的贡献，有些地方还不遗余力地支持当地落后产能项目日即使他们清楚地知道一些地方钢铁项目的产量明显落后，政策倾斜。
