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.
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.
