EN-GJS-400-15 vs EN-GJS-600-3
Side-by-side chemical composition and mechanical property comparison.
Overview
EN-GJS-400-15
5.3106
Ferritic ductile (spheroidal graphite) cast iron with minimum tensile strength 400 MPa and minimum elongation 15%. The most widely used ductile iron grade worldwide. Spheroidal graphite morphology achieved by magnesium treatment provides far superior ductility and impact resistance compared to grey iron. Used for water and gas pipes, valve bodies, pump housings, automotive components, gearbox housings, and general engineering castings. Equivalent to DIN GGG40, ASTM A536 60-40-18, JIS FCD400.
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.
