Summarization of Relationship between Tensile Strength and Hardness of Iron-Steel Materials
The relationship between tensile strength values and hardness values of iron-steel materials was summarized. Statistics showed that the tensile strength values of most iron-steel materials were directly and linearly related to their hardness values. However, due to the influences of chemical composition and manufacturing process (e.g. Casting, forging, rolling, heat treating, etc ) there was quite big dispersion existing in the conversion relationship between tensile strength values and hardness values of iron-steel materials. Therefore, the possibility of using the hardness test to control castings quality would depend on the stability of the production conditions.
