Standardization of Rockwell Hardness Test Blocks.

However, because of the historical precedent and continued common usage, force values in kgf units and saee diameters in inch units are provided for information and much of the discussion in this standard refers to these units. This sae j417 may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful sae j417 quality control and selection of materials.

Where more precise conversions are required, they should be developed specially sae j417 each steel composition, heat treatment, and part. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior sae j417 use.

The same type and size indenters may be used for either test, depending on the scale being employed. Rockwell Hardness Standardizing Machines.

The significant differences between the two tests are that the test forces are smaller for the Rockwell superficial test than for the Rockwell test.

Accordingly, throughout this standard, the term Rockwell will imply both Rockwell and Sae j417 superficial unless stated otherwise. The tables in this report give the approximate relationship of Vickers Brinell, Rockwell, and Scleroscope hardness values and corresponding approximate tensile strengths of steels. This report lists approximate hardness conversion values; test methods for Vickers Hardness, Brinell Hardness, Rockwell Hardness Rockwell Superficial Hardness, Shore Hardness; and information regarding surface preparation, specimen thickness, effect of curved surfaces, and recommendations for Rockwell surface hardness testing for case hardened parts.

The accompanying conversion tables for steel hardness numbers are based sae j417 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, sae j417, normalized, and quenched and tempered sae j417, provided they are homogeneous.
