Stainless steel bolts refer to stainless steel bolts, including stainless steel SUS201 bolts, stainless steel SUS304 bolts, stainless steel SUS316 bolts and stainless steel SUS316L bolts. The performance grades of stainless steel bolts, studs and studs are divided into 10 grades: from 3.6 to 12.9. The number in front of the decimal point represents 1/100 of the tensile strength limit of the material, and the number behind the decimal point represents 10 times of the ratio of the yield limit to the tensile strength limit of the material. 1.
