A2-70 and A4-80 stainless steel hexagonal bolts are austenitic stainless steel bolts, where A2 represents 304 material and A4 represents 316 material.
The strength grade of A2-70 stainless steel bolts is 700MPa, which has good corrosion resistance and formability. The strength grade of A4-80 stainless steel hexagonal bolts is 800MPa. Compared with 304 stainless steel, A4 material (316 stainless steel) has better corrosion resistance and higher strength, especially in chloride environment or marine environment.
