305 stainless steel has added nickel, but reduced chromium content, compared with 304 stainless steel, its corrosion resistance and strength is lower. 305 stainless steel is suitable for low strength bolts, nuts, screws and other fasteners, as well as the manufacture of certain chemical equipment. While 304 stainless steel contains 18% chromium and 8% nickel, it has good corrosion resistance and strength, and is widely used in the manufacture of various chemical equipment, food processing equipment, medical equipment and other fields.
When choosing stainless steel materials, you need to determine the material type according to the specific use environment and requirements to ensure its performance and service life.
