The surface materials of bathroom cabinets can be divided into natural stone, jade, artificial stone, fireproof board, baking paint, glass, metal and solid wood, etc.; the base material is the main body of the bathroom cabinet, which is concealed by the surface material. The substrate is the determining factor for the quality and price of bathroom cabinets.
Now the stainless steel plates on the market are made of high-quality stainless steel plates and other materials through several processes, which are environmentally friendly, moisture-proof, mildew-proof, rust-proof, waterproof, do not produce any harmful substances, beautiful and durable, and stainless steel plates can also be recycled and reused. Commonly used plates are 202#, 304#, 201#, and other specifications.
However, the 200 series stainless steel plate hardly controls the sulfur and carbon content according to the national standard and replaces part or all of the nickel with manganese (and nitrogen) to produce austenitic stainless steel with lower nickel content. The disadvantage of this series of materials is that the 18% chromium content and the low nickel content are not balanced and ferrite is formed. For this reason, the chromium content in the 200 series stainless steel is reduced from 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 passivation under acidic conditions common to corrosion sites in deposition zones and crevices. 200 series steel will fail at these conditions approximately 10-100 times faster than 304 stainless steel. In addition, the residual sulfur and carbon content in these steels is often not controlled during production, and the material cannot be traced back to its source, even when the material is recycled.
