DIN / ISO A2 stainless steel is corrosion-resistant steel; also known as ASTM-304.
A2 / ASTM-304 is an 18/8 stainless steel: metallurgical content is 18% chromium and 8% nickel.
The bolts labeled A2-70 are 304 stainless steel bolts with a tensile strength of 700 N / mm2 (see the table below).
-70 stands for tensile strength divided by 10.
Ratings of -50 and -80 are also available, but not very common.
A2 / 304 stainless steel is a so-called austenitic stainless steel: (mostly) non-magnetic.
Although some residual magnetism can be introduced during cold working of the material.
A2 / 304 stainless steel is one of the most corrosion resistant materials that designers and engineers can use.
