Stainless steel is very common in our lives, it has many uses, and there are many types of products made of it. Stainless steel has different models, is a very wide range of materials, 304 stainless steel and 201 stainless steel is a large number of stainless steel materials in the two kinds. 304 stainless steel is a very common stainless steel models, has good corrosion resistance and molding. Next let us come together to understand some of the difference between 304 stainless steel and 201 stainless steel and 301 stainless steel price introduction.
304 stainless steel and 201 stainless steel difference
1, specifications: commonly used stainless steel plate is divided into 201 and 304 two models, the actual is a different composition, the 304 quality is better, but the price is expensive, 201 is poorer. 304 for the imported stainless steel plate, 201 for the domestic Stainless steel plate.
2, 201 composition of 17Cr-4, 5Ni-6Mn-N, is section Ni steel, 301 steel alternative steel. After cold working with magnetic, used for railroad vehicles.
3, 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy and so on.
4, 201 is high in manganese, the surface is very bright with a dark black bright, high manganese prone to rust. 304 contains more chromium, the surface shows a matte, not rust. Two kinds of put together there is a comparison. The most important thing is that the corrosion resistance is different, 201 corrosion resistance is very poor, so the price is much cheaper. And because 201 contains low nickel, so the price is lower than 304, so the corrosion resistance is not as good as 304.
5, the difference between 201 and 304 is the nickel content. And the price of 304 is now more expensive, generally close to 50000 a ton, but 304 can at least ensure that the use of the process will not rust. (Available potion experiment)
6, stainless steel is not easy to rust because of the formation of chromium-rich oxides on the surface of the steel body can protect the steel body, 201 material belongs to the high manganese stainless steel hardness than 304 high carbon low nickel.
7, the composition is different (mainly from the carbon, manganese, nickel, chromium content to distinguish between 201 and 304 stainless steel)
Steel carbon (C)? Silicon (Si)? Manganese (Mn)? Phosphorus (P)? Sulfur (S)? Chromium (Cr)? Nickel (Ni)? Molybdenum (Mo)? Copper (Cu)
AISI (304)? ≤0.08?≤1.00?≤2.00?≤0.045?≤0.03?18-20?8-10
AISI(201)? ≤0.15?≤1.00?5.5-7.5?≤0.05?≤0.03?16-18?3.5-5.5
Introduction of the price of 304 stainless steel
Price of 304 stainless steel, according to the different forms of the material, the price is slightly increased or decreased, is about $16,000 per ton . (Price from the network for reference only)
304 stainless steel is widely used in the production of life, it has good corrosion resistance and high temperature resistance, and its plasticity and formability is also very good, in some industrial production as well as furniture and decorative and food and medical fields have applications. 304 stainless steel is a kind of stainless steel type that can be generalized, in the production with It is a universal stainless steel type with extremely high production requirements. Stainless steel in the construction industry also has a very wide range of applications, his different models can be used in different industries, is a kind of multi-functional material.
