33CrMoV12-9 vs EN-GJS-500-7
Side-by-side chemical composition and mechanical property comparison.
Overview
33CrMoV12-9
1.8522
Premium nitriding steel with high chromium content (2.8–3.3%) providing exceptional surface hardness after gas or plasma nitriding (up to 900 HV). Excellent core strength (900–1100 MPa tensile) with good toughness. Used for gears, crankshafts, cylinders, spindles, and precision machine components in aerospace, automotive, and power generation. Also known as 32CDV13 (AFNOR) and AMS 6481.
EN-GJS-500-7
5.3200
Ferritic-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.
