301 stainless steel specifications for heat treatment: solid solution, 1010~1150 DEG C, quick cooling. From the metallography point of view, because the stainless steel contains chromium, the surface forms a very thin chromium film, which separates from the oxygen penetrated by the steel. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium. 301 is the most widely used stainless steel, heat-resistant steel. Used in food production equipment, chemical equipment, nuclear energy and so on.

BBN steel have been export of 301 stainless steel for 17 years, BBN Steel is the biggest one of suppliers in China. We offered the301 stainless steel by the praise new and old customers. If you need 301 stainless steel, contact BBN Steel as soon as possible.
