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.
Cold rolled non decarbonization cold rolled strip was annealed under protective atmosphere. The protective atmosphere consists of a single inert gas, argon or helium, but also includes mixed gases. By adjusting the composition of these mixed gases, the speed of redox, decarbonization and Carburization in the annealing process of strip steel is equal, so as to realize the non-oxidation and non-decarbonization annealing of strip steel. After annealing, bright precision tubes should be decarburization. The annealing factor of the bright tube depends on the atmosphere and redox reaction. And other inert gases are neutral protective atmospheres of steel. It is widely used, but the oxygen atmosphere must be removed to play a good protective role. Commonly used mixed protective atmospheres.结构用无缝钢管（GB/T8162-2008）是用于一般结构和机械结构的无缝钢管。流体输送用无缝钢管（GB/T8163-2008）是用于输送水、油、气等流体的一般无缝钢管。内外涂塑复合钢管是以焊接钢管为基材 可在受污染的海水光亮精密管退火可保持光亮管的外观精度，尺寸精度高，越来越受到客户的青睐。

Based on the slow operation of the market, shipping fatigue and late market sales pressure may increase. In the current market demand, is a thorny problem, although early businessmen hope to adjust the market demand through price, but the low price adjustment can not mobilize the enthusiasm of terminal procurement. 山东大鼎金属材料有限公司
山东大鼎钢管厂 the market is about to enter the off-season, it may be difficult to increase market demand in the short term, enterprises do not want market prices to continue to fall, or to continue to stabilize prices in the short term. Spot resources are few, but the mainstream regional resource specifications are relatively complete. Based on less market turnover, although there are still a few resources to be replenished in the market, most enterprises will not increase excessive inventory.
