The conversion tables in Appendixes A ~ G of this standard are applicable to. - Non-alloy steels, low-alloy steels, cast steels; - Quenched and tempered steels; - Cold-worked steels; - High-speed steels; - Cemented carbides; - Non-ferrous metals and alloys; - Tool steels. Note 1.The conversion tables in Appendixes B ~ G are based on empirical results derived from regression analysis. A similar analysis could not be performed for the conversion table in Appendix A due to insufficient measurement data. Note 2.Appendix H provides information regarding the effects of deviating from the standard hardness testing procedures. Conversion values obtained using this standard apply only to the specific materials tested; for other materials, they serve only as a reference. In no case shall converted values replace hardness values, which are obtained through the correct testing method; furthermore, estimating tensile strength using the conversion values in this standard is the least reliable form of conversion, as compared to conversions between hardness values. Basic Data Standard ID GB/T 33362-2016 (GB/T33362-2016) Description (Translated English) Metallic materials -- Conversion of hardness values Sector / Industry National Standard (Recommended) Classification of Chinese Standard H22 Word Count Estimation 107,158 Date of Issue 2016-12-30 Date of Implementation 2017-09-01 Adopted Standard ISO 18265-2013, IDT Regulation (derived from) National Standard Notice No.27 of 2016 Issuing agency(ies) General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary This standard specifies the conversion principle between the hardness values ??and the hardness values ??and the estimated values ??of the tensile strength, and gives the general rules for the use of the conversion tables. The conversion tables in Appendix A to Appendix G of this standard apply to: - non-alloy steel, low alloy steel and cast steel; - quenched and tempered steel; - cold working steel; - high speed steel; - hard alloy; - ferrous metals and alloys; Tool steel. The conversion values ??obtained using this standard can only be applied to specific materials to be tested and are for reference only to other materials. In any case, the conversion value can not be substituted for the hardness value measured by the correct test method, and the reliability of the tensile strength is estimated to be the lowest by the conversion of this standard as compared with the conversion between the hardness values.
