40CrMoV4-6 vs EN-GJS-400-15
Side-by-side chemical composition and mechanical property comparison.
Overview
40CrMoV4-6
1.7711
Chromium-molybdenum-vanadium creep-resisting steel for high-temperature fasteners and bolts per EN 10269. Excellent creep resistance up to 540°C with tensile strength 850–1000 MPa after quenching and tempering. Widely used for steam turbine bolts, pressure vessel fasteners, and power generation components. Equivalent to ASTM A193 Grade B16.
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.
