The Difference between Carbon Steel and Stainless Steel

图片
Many things we used in the daily life are made of   stainless steel   and carbon steel, which are hard and corrosion-resistant. So what are the different between them? Following we will talk their differences from 4 aspects. 1. Composition. Stainless steel contains aluminum alloy and other kinds of material, which are resistant to acid, alkali and oxidation. Carbon steel is has carbon content of 0.0217%-2.1%, also it contains a small amount of silicon. 2. Density. The density of carbon steel is higher than stainless steel. 3. Resistance. Stainless steel has a higher resistivity than carbon steel. 4. Magnetism. Stainless steel has magnetic induction, which will produce magnetic induction when it is cold processed, and it can be demagnetized by scalding with hot water.

Processing Requirements for 201 Stainless Steel Pipe as Display Rack

Due to the low price of   201 stainless steel pipes , customers use 201 stainless steel pipes to make display racks, counters, etc. for its cost-effective,  The surface of stainless steel display racks and counters are required bright, and the surface finish needs to be 600 mesh or 800 mesh. The surface finish of 201 stainless steel pipe is about 400 mesh, so it needs to be polished again. However, some poor-quality 201 stainless steel pipes may have problem such as sand holes and sand holes after polishing, and lower corrosion resistance. In addition, making exhibition products also requires stretch bending, bending and so on. Therefore, the 201 stainless steel pipe used as props must be the raw material of the refining furnace to avoid problem in the process. If it is corrosive in the use environment, such as hospitals, chemical plants, etc., it is necessary to use 304 stainless steel or better, but general shopping malls can take 201 stainless steel pipes as display rack ma...
