    Hardness inspection is popular and simple for steel. There is some relation between Tensile Strength with Hardness for steel because both Tensile Strength and Hardness depend on the Deforming capability. The higher tensile strength, the higher capability of anti-deforming, and the higher hardness. The conversion between Tensile Strength with Hardness of steel is roughly and not exact. If you need exact data, you need inspect the specific specimen.
