It mainly depends on what occasion you use it for? The following is for reference only. Pumps: The vast majority of metal materials are not resistant to hydrochloric acid corrosion (including various stainless steel materials); high-molybdenum high-silicon iron can only be used in hydrochloric acid at temperatures below 50°C and concentrations of less than 30%. Unlike metal materials, the vast majority of non-metallic materials exhibit good corrosion resistance to hydrochloric acid; therefore, rubber-lined pumps and plastic pumps (such as polypropylene, fluoroplastics, etc.) are the best choices for transporting hydrochloric acid. Container types: Atmospheric pressure containers; polypropylene and polyethylene materials are the best choices ； Pressurized containers, metal containers lined with rubber or fluoroplastic, glass containers
As a supplementary point, stainless steel materials such as 304 are primarily susceptible to corrosion caused by chloride ions. In contrast, 316L stainless steel has better resistance to hydrochloric acid corrosion. If the pressure requirements are not high, it is better to use non-metallic materials.
The material that is used most often is fluoroplastic
