As we all know, the strength of austenitic stainless steel 304 and 316 fasteners is divided into 70 or 80 grades (such as A2-70, A4-70 or A2-80, A4-80), many people will ask the equivalent of carbon steel tightness What is the firmware level?
According to the requirements of the Circumvention 098.1-2000 standard, the tensile strength of austenitic stainless steel fasteners of grade 70 is between grades 6.8 and 8.8 of the strength of carbon steel, and grade 80 is similar to grade 8.8 of carbon steel strength. If necessary, the corresponding replacement can be made.
