Buy Stainless Steel Sheet Metal
Stainless steel sheet used widely in the variety of industry and the demand of stainless steel is increasing by recently year. It have hot rolled and cold rolled per the process. 0.5-4mm thickness is belongs to thin sheet; 4.5-35mm is belongs to thick
Stainless steel plate surface is smooth, high plasticity, toughness and mechanical strength, it can resist acid,alkali of gas and other corrosion element .It is a kind of not easy rusty steel alloy.
Chromium has the very high chemical stability, can be formed in the steel surface passivation membrane, isolated the metal with environment, protect steel from oxidation, increase the corrosion resistance of steel sheet. After passivation membrane damage, corrosion resistance is decreased.
In order to ensure that all kinds of stainless steel sheet yield strength, tensile strength, elongation and hardness and other mechanical properties conform to the requirements, before delivery the steel need to annealing, solid solution treatment and aging treatment, heat treatment.
We can compare the stainless steel sheet between 201 and 304:
1. specifications: the commonly used material is divided into two kinds of models 201 and 304, the actual is composition, 304 quality is better, but the price is expensive, 201.304 for imports of stainless steel plate, 201 for the domestic stainless steel plate.
2. 201 to 17 Cr - 4.5Ni - 6Mn - N, it is Ni section steel, replaced 301 steel. After cold working with magnetic, used in railway vehicles.
3. 304 composed of 18Cr - 9 Ni, is the most widely used stainless steel, heat-resistant steel. Used in food production equipment, wast, general chemical equipment, nuclear power, etc.
4. Manganese content in the 201 is higher, the surface is very bright with dark light, with high manganese is easy to rust. 304 containing chromium is more, surface is matte, not rust. Both together are compared is obvious. The corrosion resistance of the most important thing is different, the corrosion resistance of 201 is very poor, so the price is lower than that of the 304.
5. The difference between 201 and 304 mainly problem is nickel .And 304 prices are more expensive, at least we can guarantee in use process will not rust.(or doing the experiment)
6. stainless steel sheet is not easy to rust because forming a rich chromium oxide in the surface of steel body can protect the steel body, 201 materials belong to high manganese steel is 304 high hardness, high carbon low nickel.
We are the leader manufacturer in China,There are a huge amount of 304 stainless steel sheet in stock, if have any, please contact us directly by sales@jawaysteel.com
