Comparison of Dacromet bolts and 316 stainless steel bolts

     Dacromet bolts refer to bolts that are plated with Dacromet on the surface of the bolt. It is a new type of surface treatment technology. Compared with the traditional electroplating process, if only the anti-corrosion and oxidation functions are compared. Then Dacromet bolts and 316 stainless steel bolts are two common bolt materials, and they have some differences in terms of mechanical properties.
    1. Strength: The strength of Dacromet bolts is higher than that of 316 stainless steel bolts. The yield strength of Dacromet bolts is 450MPa and the tensile strength is 850MPa; The yield strength of 316 stainless steel bolts is 205MPa and the tensile strength is 515MPa.
   2. Corrosion resistance: 316 stainless steel bolts have good corrosion resistance, especially in harsh environments such as seawater. Dacromet bolts also have some corrosion resistance, but not as good as 316 stainless steel bolts.
   3. Magnetic: 316 stainless steel bolts are non-magnetic, whereas Dacromet bolts are magnetic.
   4. Scope of application: Due to the high strength of Dacromet bolts, they are suitable for occasions that need to bear large loads, such as bridges, building structures, etc.; The 316 stainless steel bolt is suitable for occasions that require high corrosion resistance, such as marine engineering, chemical equipment, etc.
   To sum up, Dacromet bolts and 316 stainless steel bolts are different in terms of mechanical properties and scope of application, and the selection needs to be judged according to the specific situation.
