添加钛、铌等微合金元素形成弥散的氮化物或碳氮化物，导致冷轧精密光亮钢管的韧脆转变温度升高。(3)晶粒尺寸对韧脆转变温度有影响，随着晶粒粗化，韧脆转变温度升高。冷轧和精密光亮钢管的晶粒脆化倾向得到了广泛的应用。高春铁（0.01% C）的Tc在该温度以下的100C完全易碎。冷轧精密光亮钢管中大部分合金元素都提高了韧脆转变温度和冷脆倾向。室温以上发生韧性断裂时，冷轧精密光亮钢管的断口为韧窝断裂，低温脆性断裂时断口为解理断裂。
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 high production capacity application rate. Up to.0%, the rate of increase was normal.
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.
