316 stainless steel is preferred in the stainless industry due to a number of key reasons. Grade 316 is the standard molybdenum-bearing austenitic grade, which is highly resistant to pitting and crevice corrosion in chloride environments. So 316 stainless steel is more commonly used in situations where higher corrosion resistance is required. For example, in marine engineering, 316 stainless steel is often used to manufacture ship parts, subsea pipelines, offshore platforms and other facilities. In the chemical industry, it is also commonly used to manufacture equipment such as storage tanks, reactors and pipelines. In addition, in the medical field, 316 stainless steel is also widely used to manufacture medical devices and implants due to its excellent biocompatibility and corrosion resistance.
