18 Years Factory Stainless Steel Coil Tubing Heat Exchanger - 201 stainless steel coil – Zheyi Detail:

Description

A few days ago in Seoul ISSF(International Steel Association stainless Steel Forum) conference forecast, in the low nickel austenitic stainless steel and 200 series of stainless steel may replace the 300 series of part of the market, this year will not be a serious shortage of stainless steel raw materials supply situation, Hongye stainless steel Co., Ltd. is one of the 200 series of stainless steel manufacturers.

History

The development and application of chromium manganese stainless steel in the history of the two climax is due to the reason of Ni as a strategic resource reserve, but the core problem of the rapid development of this kind of steel in China and India is due to its low cost, the cost is low, mainly reflected in the low nickel content, part of the nickel replaced by manganese; Otokhump in Europe and Arcelor in France developed and produced chromium-manganese stainless steel many years ago. The chromium-manganese series developed by them generally contains more than 4% nickel, which has better performance. The corrosion resistance of 1%Ni 200 sold on the market is very poor, far lower than 304(austenitic stainless steel), also lower than 430(ferritic stainless steel), so the industry generally do not approve of the production of a large number of L % content of chromium manganese stainless steel into the market, that should be developed with higher Ni chromium manganese series, such as 5%Ni+Cu 201 series, The corrosion resistance of this type of chromium manganese series stainless steel is close to the level of 304.

In view of the chaotic situation of the development market of chromium-manganese series, it is recommended that many steel mills and research institutions in the world develop the direction of the new 200 series. For example, the University of Biltolia has developed chromium-manganese series rod and wire which replace the high strength structure of carbon steel, and its yield strength reaches ~&gt. 400Mpa, Ni content of more than 2%, containing nitrogen elements, 202N and 204Cu developed by Arcelor, France, the former corrosion performance exceeds 304 and 316 brand, the latter is equivalent to 304, far greater than 430 brand.
