What are the application advantages and disadvantages of 200 series stainless steel?
In recent years, chromium-manganese 200 series nickel austenitic stainless steel has developed rapidly in China, and its market share is also increasing year by year. However, it should be noted that because 200 series stainless steel can only be applied to the general use of weak corrosion resistant media, its performance can not completely replace 300 series stainless steel.
In addition, sometimes because of improper material selection and other situations, 200 series stainless steel is also prone to some problems in the application process. Individual merchants in the market also have shoddy behavior, so the further expansion of the use of nickel-saving 200 series stainless steel has a certain negative impact. Therefore, it is necessary to pay attention to the reasonable selection and procurement of nickel stainless steel.
200 series stainless steel can meet the purpose of a considerable field, and has a certain alternative role for the traditional 304 market. From the application practice of Henan JBLsteel field, it can be used in almost all product fields under non-corrosion and weak corrosion conditions, and the field is quite extensive. Domestic experts have also done tests in the past in the process of developing 201, and the conclusion is that 304 can be completely replaced under weak corrosion conditions. From the civilian field of stainless steel, the application field of focusing on the use of its beauty under non-corrosion or weak corrosion conditions is also very extensive, and with the improvement of people's living standards, this application field may be further expanded.
200 series, 300 series, 400 series - different series of stainless steel products, because of their different costs, the range of use and performance are different, so there are different price levels. Generally speaking, 400 series does not contain nickel, the price is lower; 200 series stainless steel contains a small amount of nickel and a higher content of manganese, the price is higher than 400 series stainless steel, but it is much cheaper than 300 series stainless steel with a higher nickel content.
In general, 200 series stainless steel cold rolling instead of 304 in civilian appliances is more suitable, 200 series hot rolled stainless steel for medical equipment, food equipment, paper equipment also depends on the use of these equipment environment, if some medical equipment if it is used for high corrosion environment to often contact with some acid and alkaline drugs it is not suitable. However, in theory, 200 series stainless steel used as medical equipment, food equipment, paper equipment should still be feasible, but the more ideal is 304 stainless steel.
So if your equipment is in a chloride ion enriched environment, the best way is to change the material of the equipment, if you insist on using stainless steel, it is best to be psychologically prepared.
