Mechanical and technological properties of steel

Parameters describing the usefulness of steel in the economy (values depend on the alloy-composition and the sort of treatment):

tensile strength (also compressive strength, bending, shear and torsion strength)

 resilience – the physical property of material that can resume its shape after being stretched or deformed

plasticity – the ability of the material to remain deformed after the cessation of load

ductility – the ability of the material to preserve its properties during such treatment as pressing, bending or straightening

shock resistance – toughness

hardness – the ability of a material to resist when you try to press harder objects

weldability – steel feature which allows you to perform persistent connections by welding

environmental resistance – resistance to elevated or low temperatures, resistance to chemical or atmospheric corrosion
