Yield: ≥235MPa
Impact: JR=20°C / J0=0°C / J2=-20°C
Functional Equivalent: Q235FTC ≈ S235J0 (0°C impact, Q235FTC requires higher 47J)
Note: Q235FTC is specifically designed for wind power applications with guaranteed low-temperature impact toughness (0°C, 47J). S235J0 under EN 10025-2 offers 0°C impact (≥27J), while Q235FTC provides higher energy absorption.

Domestic Grade Comparison: Q235FT Series & Q275FTC

Q235FTB
Impact: 20°C

Yield: ≥235MPa

Tensile: 360-510MPa

Impact Energy: 47J

Q235FTC ★
Impact: 0°C

Yield: ≥235MPa

Tensile: 360-510MPa

Impact Energy: 47J

Q235FTD
Impact: -20°C

Yield: ≥235MPa

Tensile: 360-510MPa

Impact Energy: 47J

Q275FTC
Impact: 0°C
