33CrMoV12-9 vs EN-GJS-400-15
Side-by-side chemical composition and mechanical property comparison.
Overview
33CrMoV12-9
1.8522
Premium nitriding steel with high chromium content (2.8–3.3%) providing exceptional surface hardness after gas or plasma nitriding (up to 900 HV). Excellent core strength (900–1100 MPa tensile) with good toughness. Used for gears, crankshafts, cylinders, spindles, and precision machine components in aerospace, automotive, and power generation. Also known as 32CDV13 (AFNOR) and AMS 6481.
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.
