It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance. Series & mdash; Martensitic precipitation hardening stainless steel.Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, we can give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been used for nearly years. The ninetieth generation of the last century plans to replace it. Because the oak material is not modern enough, the container leaks due to corrosion days after it is replaced with stainless steel.
