The designation A4-80 derives from “A” meaning the material is a cold worked austenitic stainless, divided into 5 grades (1-5, hence the “4”) according to material characteristics (see Annex B of DIN ES ISO 3506-1: 1997 for full description of each grade). The “80” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-80 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a minimum tensile strength of 800 N/mm2 (MPa).
