35NiCr6 vs EN-GJS-400-15: 26% composition overlap. Significantly different materials serving different application areas.
35NiCr6 vs EN-GJS-400-15
Side-by-side chemical composition and mechanical property comparison.
Overview
35NiCr6
1.5815
Nickel-chromium quenched and tempered steel with 1.2–1.6% Ni and 0.9–1.1% Cr for high strength and excellent impact toughness. Good hardenability for uniform properties in medium cross-sections. Used for heavy-duty engine parts, crankshafts, gears, shafts, piston rods, and bolts. Important grade in aerospace (AIR 9160/C as 35NC6) and heavy mechanical engineering.
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.
