The hardness of 316L is ≤187HB. The hardness of 316L stainless steel is not high, which is much better than 304. The high hardness is mainly due to the high carbon content, and the C of 316L is ≤0.03.
316L stainless steel is also called acid-resistant steel. Its corrosion resistance is better than 304 stainless steel and its corrosion resistance is very good. Whether it corrodes or not depends on concentration and temperature. Generally, high temperature and high concentration are corrosive.
316L corrodes faster under reducing acids at room temperature, such as hydrochloric acid, dilute sulfuric acid, HF, chromic acid, hypochlorous acid, bromic acid, etc. Generally, if severe corrosion occurs, there may be cracks and pores on the surface, acidic substances Caused by penetration into the interior.
