Mechanical Properties of HY100 Steel

Steel is composed of different elements, including iron, tungsten, vanadium, chromium, manganese and carbon. HY 100 steel has low carbon content. It is generally used in nautical construction. HY 100 steel has good ductility, high tensile strength, notch stiffness, weld ability and corrosion resistance. This tempered and doused steel alloy is also used for constructing large structures and military equipment.

Tensile Strength

The tensile strength of steel is specified by the maxima of its stress-strain curve. It refers to the stress a metal can bear till it breaks. Tensile strength of HY-100 steel is equal to 689 MPa or more—the stress at which the HY-100 steel converts into plastic deformation from its original elastic deformation. The value of the tensile strength depends on the heat of the test surroundings and on the magnitude of the test sample.

Elasticity Modulus

An elastic modulus is the numerical depiction of a material’s propensity to be deformed when a force is applied to it. These deformations are non-permanent, or elastic. The elasticity modulus of HY-100 steel is 205 GPa. In simple language, it is a measurement of the hardness of HY-100 and it remains stable above a range of stress.

Poisson’s Ratio

Poisson’s ratio is the ratio of lengthwise extension strain to the crosswise contraction strain in the direction of force applied. Usually, softer materials have higher Poisson’s ratios than stiffer materials. The Poisson’s ratio of HY-100 steel is 0.280.

Shear Modulus

The shear modulus measures the resistance of the material to slide over atomic planes in metal crystal. It is calculated according to the deformation of a material when a force is applied parallel on one of its surfaces and the opposing force is applied to the opposite face. The shear modulus of HY-100 steel is 80.0 GPa.
