① +QT = quenched and tempered; +AT = solution annealed; +P = precipitation hardened;+A=Soft annealed
*Austenitic grades X55CrMnNiN20-8 to X33CrNiMnN23-8 may show hardness values which cannot be converted into tensile strength
values acording to the standard tables commonly used in laboratories. Therefore, in cases of dispute only the tensile strength value
shall be considered as valid.
