1.   304 stainless steel plate   is shiny and has a good gloss with smooth touching, while 201 stainless steel plate is dark and has no gloss with rough uneven touching. In addition, touching both of them with wet hands, the water-stained on the 304 stainless plate are easier to erase than 201 stainless plate. 2. Using a grinder to install the grinding wheel to grind and polish the two plates gently. When grinding, the sparks of the 201 stainless plate are longer, thicker,  in the contrary, the sparks of the 304 stainless plate are shorter, thinner, and less. 3. Apply stainless steel pickling paste to two stainless steel plates respectively. If the color is dark, it is 201 stainless plate, and if it is white or does not change color, it is 304 stainless steel plate. With the advancement of technology,  Changsha HCADTO Stainless Steel Co., Ltd.  special materials such as stainless steel colorful plates, colored water corrugated plates, and colored stainless steel...

316 and 304 stainless steel   are austenitic stainless steels, both of them are have good characters such as rust resistance and corrosion resistance. However, there are obvious differences in high temperature mechanical properties and special medium corrosion resistance. HCADTO will tell you the differences between the them: 1. Corrosion resistance: the corrosion resistance of them are similar, but 316 stainless steel has added molybdenum on the basis of 304 for corrosion resistance, so the corrosion resistance of 316 stainless is better when the content of chloride ions is higher . 2. Price: 316 stainless steel has added molybdenum and nickel, so the price is a little higher than 304 stainless steel. 3. Uses: Both 304 and 316 stainless steel are food grade, but 304 stainless steel is usually used in household appliances and household containers, and 316 stainless steel is used in the production of medical equipment and tools.

Stainless steel coils   are manufactured using hot rolling stainless steel slabs in a reheat furnace at a certain high temperature between 1,100° C to 1,300° C depending on the grade of the steel used for the manufacturing process. After continuously running it through heating and rolling mills, the product is coiled. Finally, the stainless steel coils are passed through the annealing and pickling lines for softer and brighter surface finish. What are the types of stainless steel coils? As discussed above, steel coils are made by winding or coiling a steel strip or sheet under very high temperatures. Depending on the production method, we can classify steel coils into four main types: hot rolled, cold rolled, carbon coil, galvanised Let us understand the types and uses of stainless steel coils: Hot rolled steel coil: Made from semi-finished products, these steel coils are rolled, annealed, and reduced to a certain thickness and rolled into coils. This type of steel coil is used in ...

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.

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...

When brown rust spots appeared on the surface of   304 stainless steel pipes , the customers may doubt that stainless steel would never rust, it must have quality problem. In fact, this is one-sided misconception about stainless steel. Stainless steel also can get rusty under certain conditions.  Stainless steel has the ability to resist atmospheric oxidation, also has the ability to resist corrosion in media containing acids, alkalis, and salts. But the resistance to corrosion is different with the chemical composition, working conditions and surrounding medium type and change. For example, 304 steel pipes has absolute good resistant corrosion in the dry cleansing air, but not in sea fog. Therefore, not any kind of stainless steel can resist corrosion and rust at any time. The are some condition that we shoule take care for it may cause damage to the protective film on the stainless steel surface and lead to corrosion.  1. Cleaning and scrubbing stainless steel pipe freq...
