stainless steel screw strength

Do you know the stainless steel screw strength you are using now? What grade is the strength of stainless steel screws? Today, Shi Shi Tong screw manufacturer would like to discuss the strength of stainless steel screws with you.

Usually we know the strength of the screw is 4.8, 6.8, 8.8, 10.9, 12.9, but this is only for carbon steel screw, because carbon steel can be hardened heat treatment, so it can be through heat treatment to increase the strength of the screw. But stainless steel screws can not be hardened heat treatment, so stainless steel screw strength generally depends on which stainless steel you use.

The types of stainless steel screws are stainless steel A1 screws (stainless steel screws 201), stainless steel A2 screws (stainless steel screws 304), stainless steel A4 screws (stainless steel screws 316). The stainless steel screw strength grades generally have 45, 50, 60, 70, 80.

Take stainless steel A2-70 for example: A2 represents the material group, that is, the second group of austenitic steel A2, 70 represents the performance grade of the product, the number of which is 1/10 of the nominal tensile strength, that is, the product’s performance tensile strength of 700 N/mm2.

The Shi shi tong screw factory can be customized stainless steel screw strength according to your needs. annie.li@szsst88.com
