Product Overview

Product Overview

QUEND 700 is a premium-grade, quenched and tempered (Q&T) structural steel plate with a minimum yield strength of 700 MPa, designed for applications where high strength and reduced weight are essential. Manufactured by NLMK Clabecq (Belgium), QUEND 700 delivers superior mechanical properties, fatigue resistance, and formability, making it ideal for lifting equipment, heavy transport vehicles, mobile cranes, trailers, and structural applications.

Thanks to tight control over the production process, QUEND plates offer excellent flatness, consistent thickness tolerance, and high notch toughness even at sub-zero temperatures.

Key Features

Minimum yield strength: 700 MPa
Excellent weldability and formability
Guaranteed impact toughness at -40°C
Outstanding flatness tolerance (≤ 3 mm/m)
Optimized for laser/plasma cutting and bending
Weight savings for high-load structural designs
