30NiCrMo16-6 vs EN-GJS-600-3: 30% composition overlap. Significantly different materials serving different application areas.
30NiCrMo16-6 vs EN-GJS-600-3
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-600-3
5.3201
Mainly pearlitic ductile cast iron with minimum tensile strength 600 MPa and minimum elongation 3%. High-strength grade achieved through predominantly pearlitic matrix, often with Cu or Sn additions as pearlite stabilizers. Used for camshafts, gears, high-stress housings, heavy-duty hydraulic components, press frames, and load-bearing structural castings where high strength is more important than ductility. Equivalent to DIN GGG60, JIS FCD600.
