EN-GJL-200 vs EN-GJL-350
Side-by-side chemical composition and mechanical property comparison.
Overview
EN-GJL-200
0.6020
Grey cast iron with lamellar graphite and minimum tensile strength 200 MPa. Ferrite-pearlite matrix. Good balance of castability, machinability, and moderate strength. Excellent vibration damping. The most economical grey iron grade for general engineering. Used for machine bases, pump housings, valve bodies, pipe fittings, brake drums, and general-purpose castings. Equivalent to DIN GG20 and ASTM A48 Class 30.
EN-GJL-350
0.6035
Grey cast iron with lamellar graphite and minimum tensile strength 350 MPa. The highest standard strength grade. Fully pearlitic or even bainitic matrix with possible alloying (Cr, Cu, Ni) to achieve high strength. Reduced machinability compared to lower grades. Used for heavy-duty cylinder liners, large diesel engine blocks, high-performance brake discs, press frames, and heavily loaded machine components. Equivalent to DIN GG35 and ASTM A48 Class 50.
