QUENCHING, SURFACE TREATMENT AND HARDNESS TESTS
CONVERSION TABLE OF HARDNESS
Excerpt from SAE J 417 (1983) Heat-treatment for steel materials
Conversion table for approximate values for steel according to Rockwell hardness C scale ( 1 )

Name	Vickers hardness (HV)	Quenching depth (mm)	Strain	Applicable material	Typical materials	Re mark
Through hardening	Max. 750	Full depth	Varies according to material.	High-C steel 00.45%	SKS3 SKS21 SUJ2 SKH51 SKS93 SK4 S45C	• Not applicable to long or precision parts such as spindles, etc.
Carburizing and qııenching	Max. 750	Standard : 0.5 Max. 2	Moderate	Low-C steel C<0.3%	SCM415 SNCM220	• Quenching parts. • Quenching depth specified on drawings. • Applicable to precision parts.
High frequency quenching	Max. 500	1—2	High	Mediıım-C steel C0.3~0.5%	S45C	• Quenching parts. • Expensive in small volume lot. • Good strain resistance.
Nitriding	900—1000	0.1 —0.2	Low	Nitriding steel	SACM645	• Obtains highest hardness ol all quenching techniques. • Applicable to precision parts. • Applicable to spindles for radial bearing.
Tuftriding	Carbon steel: 500 SUS : 1000	0.01 —0.02	Low	Steel materials	S45C SCM415 SK3 Stainless	• Good fatigue resistance and wear resistance. • Same corrosion resistance as zinc plating. • Not applicable to precision parts because it can not be polished after heat-treatment. • Applicable to dry bearings.
Bluing				Wire rod	SWP—B	• Low-temperature annealing. • Removes internal stress in forming to enhance elasticity.

Hardness tests and applicable parts

Test method	Principle	Applicable heat-treated parts	Features	Remark
1.Brinell hardness	• A (Steel or superhard alloy) ball indenter is used to indent the test surface. Hardness is given as a quotient minus the surface area of the indent, computed from the diameter.	• Annealed parts • Normalized parts • Anchored materials	1 Applicable to uneven materials and forged products because indent is large. ©Not applicable to small or thin specimens.	JISZ2243
2.Rockwell hardness	• The Standard or test load is applied via a diamond or boll indenter. Hardness is read on a tester.	• Quenched-Tempered parts • Carburized surfaces • Nitrided surfaces • Thin sheets like copper, brass, bronze, etc.	©Hardness value obtained quickly. ©Applicable as intermediate test to actual products. ©30 types caution required.	JISZ2245
3.Shore hardness	• The specimen is set on a table. A hammer is dropped from a uniform height. Hardness is based on how high the hammer bounces.	• Quenched-Tempered parts • Nitrided parts • Large carburized parts, etc.	©Extremely easy to operate. Data obtained quickly. ©Applicable to large parts. ©İndent is kept shallow, therefore is applicable to actual products. ©Compact and light-weight. Portable.	JISZ2246
4.Vickers hardness	• Uses a diamond 136' square pyramid indenter. Hardness value is obtained as the surface area of the indent, computed from the length of the diagonal lines of the indent.	• Thin parts hardened by high frequency quenching, carburizing, nitriding, electrolytic plating, ceramic coating, etc. • Hardened layer depth in carburized and nitrided parts	©Applicable to small and thin specimens. ©Applicable to all materials because of diamond indenter.	JISZ2244
