Comparison Note: Q235FTE requires -40°C impact (34J), which exceeds standard S235J2 (-20°C, 27J). For -40°C, higher-grade low-temperature steels may be referenced.
Note: Q235FTE is specifically designed for extreme cold climate wind power applications with guaranteed -40°C impact toughness (34J). EN 10025-2 S235 series typically only guarantees down to -20°C (S235J2). For -40°C requirements, Q235FTE offers a specialized solution.

Domestic Grade Comparison: Q235FT Series & Q275FTE

Q235FTD
Impact: -20°C

Yield: ≥235MPa

Tensile: 360-510MPa

Impact Energy: 47J

Q235FTE ★
Impact: -40°C

Yield: ≥235MPa
