Cheap Stainless Steel Coil 201 stainless steel holds a certain acid resistance, alkali resistance, high density, polishing no bubble, no pinhole and other characteristics, is the production of all kinds of watch case, watchband bottom cover quality materials. Mainly used for decorative pipe, industrial pipe, some shallow stretching products. 201 Stainless steel coil price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 201 coils are very good for welding applications as they have less carbide precipitation and less localized corrosion. 201 Stainless Steel Coil Specifications: GradesStainless Steel J1, J2, J4, 201, 202, 301, 304, 304H, 304L, 309, 309S, 310, 310S, 316, 316L, 316TI, 321, 321H, 347, 409, 410, 410S, 420, 430, 441, 904L Thickness0.2mm 鈥?5.0mm Width3.2mm 鈥?1500mm Length2000mm, 2440mm, 3000mm, 5800mm, 6000mm, AS PER CUSTOMER'S REQUIREMENT Type of MaterialSTAINLESS STEEL SOFT, DEEP DRAW, EXTRA DEEP DRAW, QUARTER HARD, HALF HARD, FULL HARD.

The amount of nickel ultimately determines the rust prevention ability of pipes 1. Specification: commonly used stainless steel plates are divided into two types: 201 and 304. In fact, the composition is different. 304 is better in quality, but the price is expensive, and 201 is worse. 鈥?/p> 2. 201 is composed of 17cr-4.5ni-6mn-n, which is magnetic after cold processing and is used for railway vehicles. 鈥傗€?/p> 3. 304, composed of 18cr-9ni, is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, chemical equipment, nuclear energy, etc. 鈥傗€?/p> 4. 201 has high manganese content, the surface is very bright with dark brightness, and the manganese content is high, which is easy to rust. 304 contains more chromium, and its surface is matte and does not rust Put the two together and there will be a comparison. The most important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price is much cheaper And because 201 has low nickel content, its price is lower than that of 304, so its corrosion resistance is not as good as that of 304. 鈥傗€?/p> 5. The difference between 201 and 304 is nickel. And the price of 304 is relatively expensive now, but at least 304 can ensure that it will not rust in the process of use. (liquid medicine can be used for experiments) 6. Stainless steel is not easy to rust because chromium rich oxide formed on the surface of the steel body can protect the steel body. Material 201 belongs to high manganese stainless steel, which is harder than 304, with high carbon and low nickCheap Stainless Steel Coil website:http://www.sy-exports.net/stainless-steel-coil/
