What's NO.1 mean in   stainless steel plate   304NO.1?  NO.1 in stainless steel plate 304NO.1 means the surface of stainles steel plate, which is a classification way of stainless steel . The detailed is as follows: NO.1 silver white, which is a rough, matte surface after hot-rolled to a specified thickness, then annealed and descaled processing. NO.2D silver white, it is heat treatment and pickling after cold rolling, a kind of matte surface processing. 2D products are used for applications that do not have requirements on the surface of stainless steel plate. NO.2B, strong luster. It is a final mild cold rolling with polishing rolls to get luster. It is the most common surface finish and can also be used as a first step in polishing. BA is bright as a mirror, but is usually a bright annealed finish with a highly reflective surface. It is used for building materials, kitchen utensils. NO.3 coarse grinding. Grind NO.2D and NO.2B stainless steel plate with 100~200# (unit) ...

Which is Higher Grade 304 or 316 Stainless Steel

图片
316 and 304 stainless steel   are austenitic stainless steels, both of them are have good characters such as rust resistance and corrosion resistance. However, there are obvious differences in high temperature mechanical properties and special medium corrosion resistance. HCADTO will tell you the differences between the them: 1. Corrosion resistance: the corrosion resistance of them are similar, but 316 stainless steel has added molybdenum on the basis of 304 for corrosion resistance, so the corrosion resistance of 316 stainless is better when the content of chloride ions is higher . 2. Price: 316 stainless steel has added molybdenum and nickel, so the price is a little higher than 304 stainless steel. 3. Uses: Both 304 and 316 stainless steel are food grade, but 304 stainless steel is usually used in household appliances and household containers, and 316 stainless steel is used in the production of medical equipment and tools.
