Introduction
From a professional point of view, low alloy steel refers to the alloy steel whose total amount of alloy elements is less than 5%.
This kind of steel has high strength, light deadweight, high rigidity, good plasticity and toughness, and can withstand large deformation and pressure.
It is generally used in engineering machinery, ship bridges, high-rise buildings, boilers and pressure vessels, electricity, various vehicle manufacturing and other fields.
