30NiCrMo16-6 vs EN-GJS-500-7
Side-by-side chemical composition and mechanical property comparison.
Overview
30NiCrMo16-6
1.6747
Ultra-high-strength nickel-chromium-molybdenum steel with outstanding through-hardenability for large cross-sections. Achieves tensile strengths of 1080–1270 MPa (dia ≤40mm) with excellent impact toughness. Very high Jominy hardenability (47–55 HRC). Used for heavy-duty crankshafts, connecting rods, bolts, gear shafts, and critical aerospace structural parts. AFNOR equivalent: 35NCD16.
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.
