321 Stainless Steel And 304 Stainless Steel Plate Difference

321 stainless steel and 304 stainless steel plate difference

321 stainless steel and 304 stainless steel plates are 300 stainless steel series. First of all, let's take a look at their national brand and chemical composition.

304 stainless steel plate is universal stainless steel, the industry also referred to it as 18/8 stainless steel. Chemical composition of 304 stainless steel plate Carbon: 0.07 silicon: 0.75 Manganese: 2.00 Phosphorus: 0.045 Sulfur: 0.030 Nickel: 8.00~10.50 Chromium: 17.50-19.50 Nitrogen: 0.10.

321 stainless steel is to improve the intergranular corrosion tendency by adding TI on the basis of 304 stainless steel, and the national standard is 06Cr18Ni11Ti. 321 stainless steel chemical composition: Carbon: 0.08 silicon: 0.75 Manganese: 2.00 Phosphorus: 0.045 sulfur: 0.030 Nickel: 9.00-12.00 Chromium: 17.00-19.00 Nitrogen: 0.10 titanium: 5XC.

Let's look at their performance again.

304 stainless steel plate and 321 stainless steel in the corrosion resistance of the difference is not large, but in the heat condition of 500-600 degrees Celsius, most of the 321 stainless steel is used, because 321 stainless steel has TI as a stabilizing element, but also heat strength steel, so that it has better resistance to intergranular corrosion and high temperature strength. So can be used to manufacture wear-resistant acid containers and wear-resistant equipment lining, conveying pipes.
