Fridge rear panels require steels with high resistance and foamability.
High Strength Low Alloy steels (HSLA) are characterised by their low content of both carbon and micro-alloying elements. This gives HSLA steels outstanding functional properties, such as weldability and coatability.
The hardening achieved by controlled internal purity and fine grain size structure ensures excellent mechanical strength. HSLA combine improved weldability with good formability. The narrow variation margins for their mechanical properties make it easy to shape the steel (presses or automated lines).
They also have good fatigue and impact resistance. HSLA (HX340LAD+AZ) combined with hot dip galvanised is the best offer for this application.
