35NiCr6 vs S355J2W
Side-by-side chemical composition and mechanical property comparison.
Overview
35NiCr6
1.5815
Nickel-chromium quenched and tempered steel with 1.2–1.6% Ni and 0.9–1.1% Cr for high strength and excellent impact toughness. Good hardenability for uniform properties in medium cross-sections. Used for heavy-duty engine parts, crankshafts, gears, shafts, piston rods, and bolts. Important grade in aerospace (AIR 9160/C as 35NC6) and heavy mechanical engineering.
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.
