EN-GJS-500-7
5.3200Ferritic-pearlitic ductile cast iron with minimum tensile strength 500 MPa and minimum elongation 7%. The balanced grade offering significantly higher strength than EN-GJS-400-15 while retaining reasonable ductility. Mixed ferrite-pearlite matrix (typically 40-50% pearlite). Used for crankshafts, connecting rods, suspension components, gear housings, heavy-duty pipe fittings, and medium-stress structural castings. Equivalent to DIN GGG50, JIS FCD500.
