Which is healthier, martensitic stainless steel or 304?

These two materials are also good for health. There is no obvious difference in health between martensitic stainless steel and 304 stainless steel. They are all non-toxic metal materials and will not release harmful substances. Therefore, from a health point of view, the choice of stainless steel mainly depends on the application scenarios and performance requirements. 304 stainless steel is a general stainless steel with good corrosion resistance, high temperature resistance and machinability. It has been widely used in food processing and manufacturing. Martensite stainless steel has higher strength and hardness, and is suitable for occasions requiring high strength and wear resistance.
