20NiCrMo2-2 vs EN-GJS-600-3
Side-by-side chemical composition and mechanical property comparison.
Overview
20NiCrMo2-2
1.6523
Nickel-chromium-molybdenum case-hardening steel — the base grade of the 8620 family. Good weldability, toughness, and machinability. Case hardness up to HRC 60–63 with core strength 700–1100 MPa after carburizing and quenching. Used for gears, shafts, pinions, piston pins, and camshafts in automotive, gearbox, and general mechanical engineering. Equivalent to AISI 8620 and BS 805M20.
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.
