I was just reading ASTM E140 Standard Hardness Conversion Tables for Metals. Table 2 gives conversions for non-austenitic steels (Rockwell B hardness range) and Table 5 gives conversions for austenitic stainless steel also in the Rockwell B range. The differences are not huge but significant:
HRB 100 = 240 Brinell non austenitic
HRB 100 = 253 Brinell austenitic
Not being a metallurgist, I was wondering what the reason is for the difference? Is the austenitic stainless steel work hardening more in the Brinell test thus giving a higher reading?

The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.
