This property is known as ductility, which enables it to be used in the making of different shapes and structures ranging from thin wires or large automotive parts and panels. The mechanical properties of steel are primarily determined by the chemical composition of the steel. Yield point (σs) When the stress of steel or sample exceeds the elastic limit, even if the stress does not increase any more, obvious plastic deformation of the steel or sample continues to occur. Tensile Strength ksi. There are a measure of strength and lasting characteristics of the material in service and are of good importance in the design of tools, machines, and structures..

Also, it will enable the land surveyor to verify pile location a…. High-strength steels (HSS) are produced using special chemical composition or/and manufacturing processes. The manufacturing process does have an effect on the residual yield and tensile strength, with the “cold worked” steels presenting a greatly reduced strength with increasing heating temperature compared with the “hot rolled” steels. Malleability is closely linked with ductility and allows steel to be deformed under compression.
