This standard specifies the units of force and length in the International System of Units SI ; that is, force in Newtons N and length in millimeters mm. The tables in this sae j give the approximate relationship of Vickers Brinell, Rockwell, and Scleroscope hardness values and corresponding approximate tensile strengths of steels.

New products AWS C1. The accompanying conversion tables for steel hardness numbers are based on extensive tests on carbon and alloy steels, mostly in the heat treated condition, but have been found to be reliable on practically all constructional alloy steels and tool steels in the as-forged, annealed, normalized, and quenched sae j tempered conditions, provided they are homogeneous.

This information may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.

J Item s — proposed revisions of this standard. All numbers in these tables given in bold face type were prepared jointly by the American Society for Testing and Materials, the American Society for Metals, and SAE from carefully checked data. Portable Rockwell hardness testing machines that cannot meet the direct verification requirements and can only be verified by indirect verification requirements are covered in Test Method E Please first log in with a verified email before subscribing to alerts.

Standardization of Rockwell Indenters. The same type and size indenters may be used for either test, depending on the scale being employed. Work Item s – proposed revisions of this standard. The sae j differences between u417 two tests are that the test forces are smaller for the Rockwell superficial test than for sae j Rockwell test.

This report lists approximate hardness conversion values; test methods u Vickers Hardness, Brinell Hardness, Rockwell Hardness Rockwell Superficial Hardness, Sae j Hardness; and information regarding surface preparation, n thickness, sad of curved surfaces, j4117 recommendations for Rockwell sae j hardness testing for case hardened parts. Where more precise conversions are required, they should be developed specially for each steel composition, heat treatment, and part.
