First solve a question: Henan stainless steel does not rust rust rust of course, but not the same degree of corrosion?. The reason why there is such a question, simply because not know much due to stainless steel. The effect of different materials in different corrosion: 201 stainless steel: at room temperature, use of effective, does not rust, do not put the water, and acid-base environment. 304: high temperature of 800 degrees, acid, corrosion rust into the water three to five years, the use of the effect is very good. 321 stainless steel and 304 stainless steels, corrosion effects are particularly good, adding a ti, belong to special stainless steel plant. 316 Stainless Steel: 304 and the same, but the performance is more excellent, the best material is corrosion resistant. The best one: 310s stainless steel, based on high-temperature corrosion resistance. Company Website: http: //www.fengchengbxg.com/
