EN-GJL-250 vs EN-GJS-600-3
Side-by-side chemical composition and mechanical property comparison.
Overview
EN-GJL-250
0.6025
Grey cast iron with lamellar graphite and minimum tensile strength 250 MPa. The most widely used grey cast iron grade worldwide. Predominantly pearlitic matrix providing an excellent balance of strength, machinability, damping capacity, and castability. Used for engine blocks, cylinder heads, machine tool beds, lathe beds, flywheels, brake discs, hydraulic valve bodies, and general medium-duty structural castings. Equivalent to DIN GG25 and ASTM A48 Class 35.
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.
