1.4313 Material

1.4313 Material is a martensitic stainless steel grade, which can be hardened with heat threatment. This grade is equivalent as 1.4313 or X3CrNiMo13-4 according to EN norm and x3crnimo13 4 equivalent as UNS S41500 according to UNS norm. It starts with 415 number according to UNS norm so because of this, some sources accept this grade also as AISI 415 stainless steel. 1.4313 material is a magnetic grade and 1.4313 heat treated according to the following three different heat thereatment contitions: QT650, QT780, QT900. The numbers 650, 780 and 900 are showing the minimum tensile MPA strenght of the materials.
