  • Mechanical properties of fasteners - austenitic steel types

    Excerpt from DIN EN ISO 3506-1:2010

    Steel group Steel type Property class Tensile strenght
     Rma min. MPa    		  0.2% yield strength
     Rp0.2a min. MPa    		 Fracture elongation
     Ab min. mm
    Austeniczna A1, A2, A3, A4 oraz A5 50 500 210 0,6 d
    70 700 450 0,4 d
    80 800 600 0,3 d

     

    a - The tensile strength is calculate in relation to the strain cross-section (see DIN ISO 3506-1)
    b - The ultimate elongation is determined according to 7.2.4 on the relevant screw length and not on turned samples  d  is the normal diameter.
