The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe

精加工钢管的生产工艺与普通无缝钢管相同，是酸洗、冷轧多道次工序。产品可为粗铸件或冷件。2。精密钢管是近年来出现的产品，主要是内孔和外壁的尺寸具有严格的公差和粗糙度，外径较小。Jiangsu Shagang lowered the factory price of steel in the middle of this month, in which the price of heat preservation and anti-corrosion steel pipe was reduced by yuan and the price Shagang has a certain benchmarking role in the heat preservation and anticorrosion steel pipe market, its price has been greatly reduced, domestic mainstream steel enterprises have introduced price
It can be said that, to a certain extent, this is because of excessive interference and other local power from the private interest, the steel industry not only delayed the transfer to the upstream of the industrial chain to achieve the goal, but also made the T overcapacity In this regard, the problem of overcapacity in the steel industry has not been alleviated. In essence, it should be a question of the relationship between power and market, whether the market should play a decisive role or not.

Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast furnace start-up rate is about.0%, high production capacity application rate. Up to.0%, the rate of increase was normal.山东大鼎钢管厂、山东大鼎金属材料有限公司
