It is made of high-quality stainless steel plates and other materials through several processes. It has various styles and unique design. It is environmentally friendly, moisture-proof, mildew-proof, rust-proof and waterproof. It does not produce any harmful substances, beautiful and durable, and stainless steel plates can be recycled. . Commonly used plates have 202#, 304#, 201# and other specifications.
Disadvantages: 200 series of stainless steel plates, although the magnets are not magnetic, but the plates almost do not control the sulfur and carbon content according to the national standard, and replace some or all of the nickel with manganese (and nitrogen) to produce lower nickel. Austenitic stainless steel in the content. The disadvantage of this series of materials is that 18% of the chromium content and the low nickel content are not balanced to form ferrite. For this reason, the chromium content in the 200 series stainless steel is reduced to 15% to 16%, in some cases. It has dropped to 13% to 14%, and its corrosion resistance cannot be compared with 304 and other similar steels. In addition, manganese and, in some cases, copper reduce the effect of repassivation under the acidic conditions common in the corrosion areas of the deposition zone and the gap. The destruction rate of 200 series steel under these conditions is about 10-100 times that of 304 stainless steel. Also, it is often impossible to control the residual sulfur and carbon content of these steels in production, and the materials cannot be traced back to trace, even in the recycling of materials. If Cr-Mn steel is not specified, they will become a dangerous scrap mixed material, resulting in an unexpected high manganese content in the casting, so the 200 series of sheets will have a small brown spot after being damp in the air, after a little longer. It will rust.
