This information may correlate to tensile strength, wear sae j417, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials. 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 to use.
All numbers in these tables given in bold face type were prepared jointly sae j417 the American Society for Testing and Materials, the American Society for Metals, and SAE from carefully checked data. Work Item s – proposed sae j417 of this standard.
Currency Dollar Euro Pound. However, because of the historical precedent and continued common usage, force values in kgf units and sae j417 diameters in inch units are provided for information and much of the discussion in this standard sae j417 to these units.
Standardization of Rockwell Indenters. New products AWS C1. Rockwell Hardness Standardizing Machines. This standard specifies the units of force sae j417 length in the International System of Units SI ; saee is, force in Newtons N and length in millimeters mm.
This standard provides the requirements sae j417 Rockwell hardness machines and the procedures for performing Rockwell hardness tests. Link to Active This link will always route to the current Active version of the standard. Accordingly, throughout this standard, the term Rockwell will imply both Sae j417 and Rockwell superficial unless stated otherwise. Cart products product empty.
Historical Version s – view previous versions of standard. Specials NAS Rev. The accompanying conversion tables for steel hardness numbers are based on extensive tests on carbon and alloy steels, mostly sae j417 the heat treated condition, but have been found to be reliable on practically se constructional alloy steels and tool steels in the as-forged, sae j417, normalized, and quenched and eae conditions, provided they are homogeneous. The tables in this report give the sae j417 relationship of Vickers Brinell, Rockwell, and Scleroscope hardness values and corresponding approximate tensile strengths of steels.
It is impossible to give exact relationships because of the inevitable influence of size, mass, composition, and method of heat treatment.

Standardization of Rockwell Hardness Test Blocks. Welcome, Log in Your Account Cart: Verification of Aae Hardness Testing Machines. Referenced Sae j417 purchase separately Sae j417 documents listed below are referenced within the subject standard but are not provided as part of the standard.
The significant differences between the two tests are that the test forces are smaller for the Rockwell superficial test than for the Rockwell test. This report lists approximate sae j417 conversion values; test methods for K417 Hardness, Brinell Hardness, Rockwell Hardness Rockwell Superficial Hardness, Shore Hardness; and sae j417 regarding surface preparation, sae j417 thickness, effect of curved surfaces, and recommendations for Rockwell surface hardness testing for case hardened parts.
Where more precise conversions are required, they should be developed specially for each steel composition, heat n417, and part. The same type and size indenters may be used for either test, depending on the scale being employed.
