Stainless steel coil   able to anti-corrosion and anti-rust. Its excellent quality makes it an important industrial raw material and building material. Next, we will learn about the usage of stainless steel coil in the automotive industry. Stainless steel coil are not only strong in corrosion resistance, but also light in weight. Therefore, it has been widely used in the automobile manufacturing industry. Car shells require a lot of stainless steel coils. According to statistics, a car needs about 10-30kg stainless steel coil, while American cars need 40kg stainless steel coils. At present, some brands of automobiles in the world have begun to use stainless steel coil as structural materials of automobiles, which not only reduced the weight of automobiles, but also improved the service life of automobiles. In addition, the stainless steel coil used in buse, high-speed railway, subway, etc. its usage is becoming more and more extensive. HCADTO  focuses on providing one-stop...

With rapid economic growth, the applications of 316 stainless steel plates become widely. Our daily life is closely related to stainless steel, but many people do not know much about the performance and maintenance of stainless steel. The most commonly used stainless steel grade is 304 and 316. The main difference between the two in chemical composition is that 316 contains molybdenum, and it is widely agreed that 316 stainless steel has better corrosion resistance than 304 at high temperatures. Therefore, 316 stainless steel parts are usually used in high-temperature operating environments. Due to the addition of molybdenum elements, corrosion resistance and high-temperature strength of 316 stainless steel have been greatly improved. Its high-temperature resistance can reach 1200-1300 degrees, and it can be used under harsh conditions. 316 Stainless steel plate is typically used in marine and highly acidic environments, underwater equipment, surgical tools, food, and pharmaceutical a...

Since 2010, the specification of domestic   stainless steel angle bar   is #2-#20, which is named by the number of centimeters of the side. The same size stainless steel angle bar has 2-7 kinds of different thicknesses. The imported stainless steel angle bar indicates the actual size and side thickness of both sides and the standard. Large stainless steel angle bar has a side length over12.5cm, medium-sized stainless steel angle bar has a side length between 12.5cm-5cm, and small stainless steel angle bar has a side length that less than 5cm. The order of import and export stainless steel angle steel is generally based on the specifications required in use, and its steel grade is the corresponding carbon steel steel grade. The delivery length of stainless steel angle bar is divided into fixed length and double length. The selection range of fixed length of domestic stainless steel angle bar is 3-9m, 4-12m, 4-19m and 6-19m according to the different specifications. Changsha HCA...

 Stainless acid-resisting steel is what we usually call stainless steel -- to keep steel from rusting, it is very simple to make alloy steel by adding some metal impurities (such as adding chromium). However, not rust, only means that it will not be corroded by the air, and the performance is still poor. We also need it to resist chemical corrosion, so there is "stainless acid-resisting steel ". To make  stainless steel , you need to add many kinds of metals -- basically, there is a formula. There are only three common formulas: martensitic stainless steel, ferritic stainless steel, and austenitic stainless steel. Among them, austenitic stainless steel has the best comprehensive performance and no magnetic, so it is the most widely used one in our daily life - 304 and 316 are austenitic stainless steel. When we talk about the differences between 304 and 316 stainless steel, its formula is just like our recipe. We can change the taste of our dishes by controlling the type and ...

The differences between cold rolled steel and stainless steel are mainly reflected in three aspects, respectively, the use, characteristics, and raw materials. 1. Different applications: A. Main uses of cold rolled steel: mainly used in automobile manufacturing, electrical products, and so on. B. Main uses of stainless steel: the majority of  stainless steel products  need good welding performance of raw materials, like tableware, vacuum cup, steel pipe, water heater, water dispenser, etc 2. Different Characteristics: A. Characteristics of the cold rolled steel: Because there is no annealing treatment, its hardness is very high (HRB > 90); The machining performance is very poor, only simple directional bending less than 90 degrees can be carried out. B. Characteristics of stainless steel: weldability, corrosion resistance, polishability, heat resistance. 3. Different raw materials: A. Raw material of cold rolled steel: Cold rolled sheet is a product made of hot rolled coil ...

Because of the thermal hardness and thermal conductivity of   stainless steel pipes   are low, and it is difficult to process with wire rolling technology. The processing difficulties are in the following aspects. 1. Due to the thermal hardness of the stainless steel pipe material, the degree of correction of the thread forming by the roller during the rolling process is limited, so the rolling process needs to increase the roughness of the pipe surface; (2) The surface of the stainless steel pipe is hard, and the pressure required for rolling is higher, and its surface pressure value is 30%-100% higher than that of the carbon steel pipe of the same diameter; (3) Although stainless steel pipes with low surface hardness are easy to roll and form threads, the threads are pierced after tightening with pipe fittings, and the threads are easily damaged during disassembly and assembly; (4) The thermal conductivity of stainless steel pipes is low. During the rolling process, the temp...
