EN-GJL-250 vs S355J2W
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.
S355J2W
1.8965
The most widely used structural weathering steel with minimum yield strength 355 MPa and impact testing at -20°C (J2 designation). Forms a protective patina of stable rust that eliminates the need for painting. Cu, Cr, and P additions provide atmospheric corrosion resistance up to 8 times that of plain carbon steel. Used for unpainted bridges, outdoor sculptures, railway wagons, architectural facades, transmission towers, and containers. Equivalent to ASTM A588 / Corten B.
