Converting between different hardness scales is not an exact science, but there are many charts available that will show the approximate relationship between different scales. One chart is available at http://www.carbidedepot.com/formulas-hardness.htm Another useful website for converting between different hardness scales is http://www.efunda.com/units/hardness/convert_hardness.cfm Tianxing Testing Instruments Co. Ltd. is a professional manufacturer of portable hardness testers http://www.hardnesstesters.biz/

It can range from 10 HRc to 50 HRc it's all dependent on how it's heat treated and quenched.
The Rockwell C Hardness system uses "HRC" as a measure of hardness for various materials. A hardness of 68 HRC is extremely high and will most likely be harder than simple steel.
HRC 23-34 According to ASTM F568M (1996)
hardness as it is measured on a rockwell or brinell testing instrument
ANSWER: Rockwell (HRC) 50.Grade 420 stainless steel (Fe,
In rockwell, it should be between 23-32 HRC
Yes, a reading of 35 on the Rockwell C Scale would be considered relatively low as the scale generally ranges from 20 to 70. This indicates that the material is softer compared to higher readings on the scale.

In depends on the hardfacing technique and the final Fe dilution. Typical values range 42-45 HRC.
Sterling silver typically has a hardness of around 40 to 45 HRC on the Rockwell scale.
