The numerical part before “·” in the marking code indicates the nominal tensile strength. For example, “4″ in grade 4.8 means 1/100 of the nominal tensile strength of 400N/MM2. The meaning of “·” and the digital part after the dot in the marking code indicates the yield ratio, that is, the ratio of the nominal yield point or the nominal yield strength to the nominal tensile strength. For example, the yield point of grade 4.8 products is 320 N/mm2. Stainless steel product strength grade mark is composed of two parts separated by “-”. The symbol before “-” indicates the material. For example, A2 and A4 indicate the strength after a -, for example, A2-70
