Latham Steel stands as a proud Hamilton-based manufacturer and supplier, playing a vital role in New Zealand’s industrial landscape. For projects demanding formidable strength without excessive weight, we proudly offer EN 10025-2 S690Q sheet and plate. This high-strength, quenched and tempered steel is designed for the most demanding structural applications, providing an exceptional strength-to-weight ratio that is ideal for ambitious engineering and construction challenges right here in Aotearoa and beyond.
The composition of S690Q steel, carefully balanced with elements like carbon, manganese, and micro-alloying additions, is processed through quenching and tempering. This specific heat treatment is what unlocks its outstanding mechanical properties, delivering a minimum yield strength of 690 MPa. This means it offers incredible resistance to deformation under immense stress, coupled with good toughness and weldability, making it a reliable and high-performance material.
