High Strength, low alloy steels Flat products, hot rolled into high strength steels for cold forming 1 Description and advantages 2 Typical applications These steels conform to the European standard EN 10149.2 : 1995. This type of steel is called a high strength, low alloy (HSLA) steel. High strength, low alloy steels are characterised by low carbon and alloy element contents, which give them excellent functional properties such as suitability for cold forming, profiling, welding and coating. Their strengthening mechanisms of precipitation hardening and grain size refinement enable the achievement of high strength levels. Advantages of HSLA steels: They combine improved weldability, due to the very low carbon level, with good formability. Their mechanical characteristics facilitate forming on presses and automated lines. They are further characteriHSLA steels are generally for structural parts such as welded tubes, sed by a good resistance to fatigue and impact. beams and profiled or slightly pressed parts. Thanks to their high elasticity limit (Re), they are particularly suited when a reduction in weight is required. This is why these steels are often used to replace conventional structural steels. • Automotive: pressed chassis and reinforcement parts, beams or welded tubes.

HRC_A30 - 02 _EN HSLA steels are used in sectors such as : • Industrial vehicles, tractors, trailers and skips as chassis components (resistance to fatigue). • Lifting and handling equipment (cranes, fork lifts, platforms, warehouse shelves, lifts). • The agricultural sector for chassis and protective elements. • Roll bars, buildings, containers, urban lighting masts, concrete mixers… 80mm 960 1.12 1.15 0.00 12.70mm 960 960 10.015 0.090 0.
