Low-alloy steel
Low-alloy steels are part of a recent type of alloyed steels. They are given a special treatment that results in a remarkable increase in resistance, greater, for example, than in carbon steel.
Low-alloy grades are characterised by their high weldability and formability, although also by their high degree of brittleness. They also provide suitable mechanical properties and resistance to cracking. Their weldability depends on the carbon ratio in their composition.
They are also used to increase resistance to corrosion in specific weather conditions, particularly in general and mechanical construction.
