We all know that seawater is salty, unlike freshwater in rivers and rivers, which contains a lot of chlorine, which can react with metals Accelerates the corrosion of metals. Alloy Seamless Steel Tubes Why is  Seamless Steel Pipe  so popular in coastal areas? We all know that seawater is salty, unlike freshwater in rivers and rivers, which contains a lot of chlorine, which can react with metals and accelerate Corrosion of metal. But for stainless steel seamless pipe, stainless steel seamless pipe has very good corrosion resistance, stainless steel can be used for a long time in the marine environment, so people near the ocean or working at sea will use stainless steel pipe to use. The stainless steel seamless pipe contains molybdenum (Mo) element, which makes the stainless steel pipe itself has very strong corrosion resistance. Although...

As a  Seamless Steel Pipe Supplier , share with you. The alloy contains nearly 9% chromium and 1% molybdenum, and depending on their composition, they are also called 9 Cr 1 Mo steel. The stainless steel tube has a band-shaped martensite phase under hot rolling conditions, resulting in a higher hardness, so tempering treatment is required to reduce the hardness to obtain good workability. The recrystallization temperature of the stainless steel tube is greater than 790 ° C. The low temperature has almost no effect on the structure and performance of  Seamless Steel Pipe , and the higher tempering temperature will cause the ferrite phase and structure of the recrystallized structure to be uneven. Seamless Steel Pipe Some people have recently conducted experiments to study the effect of structure and hardness on the tempering cooling rate of stainless steel capillaries at different tempering temperatures. The results show that the hardness of 300 ~ 400 ℃ does not change m...

As an  Alloy Seamless Steel Tubing Supplier , share with you. Stainless steel products often have various cracking phenomena during the drawing process. Among them, lateral or point cracking of the side walls is a common form of processing failure of 304 stainless steel products with relatively deep drawing such as vacuum cups and pressure cookers. Especially in recent years, the product processing process has been continuously promoted. For example, the number of drawing passes of the thermal insulation cup has been reduced from 5 times to 3 times commonly used at present, from multiple annealing in the middle to one annealing or no annealing after the completion of stamping. Therefore, higher requirements are imposed on the formability of stainless steel materials. The occurrence of lateral or point-like cracking defects on the side walls of stainless steel products may be caused by intercrystalline defects of materials, delta ferrite and other materials, or it may be caused by ...

Alloy Seamless Steel Tubes  are manufactured according to regulations. Generally speaking, the methods of making stainless steel seamless tubes are generally cold-rolled, cold-drawn, and hot-rolled. It is a whole process called annealing in one step, and this whole process is critical. However, due to the fact that this whole process does not look too much in appearance, many pot friends can't tell whether stainless steel pipes have been annealed.  Alloy Seamless Steel Tubes Supplier  will teach you how to judge whether stainless steel seamless pipes are annealed? Alloy Seamless Steel Tubes (1) A resistor with a high-precision number detector for measuring the length of each water pipe unit. No impervious steel resistor is quite large and should be measurable. The natural barrier of calcined steel is smaller than that of steel without butadiene. Before modeling, it was dull and boring, and there was no solid state. ⑵The raw material of stainless steel seamless tu...

As a  Seamless Steel Pipe Supplier , share with you. In daily steel purchases, the most annoying and annoying is the purchase of inferior  Seamless Steel Pipe , which affects product quality. How to identify inferior seamless steel tubes? Let's take a look at the methods that can identify high-quality seamless steel pipes and inferior seamless steel pipes with the naked eye: Seamless Carbon Tubing 1. The surface of inferior seamless steel pipe is prone to scars. Mainly due to two reasons: (1). There are many impurities in inferior seamless steel pipe, and the material is uneven. (2) The guide and guard equipment of inferior pipe manufacturers is simple and easy to stick to steel, and the pipes containing impurities are prone to scars after biting into the roll. 2. Inferior seamless steel tubes are prone to tube folding. The so-called folding is the various fold lines formed on the surface of the seamless steel tube. This kind of defect often runs through the l...
