* S-7 is not recommended for hard coating. Call for more information.

** The hardness on some of the above steels can be raised to RC 58/61 by "post hardening." This service adds cost and time and is quoted separately.
Hot Working Die Steels
H-13
49/54
Good
On all Hot Working Die Steels it is recommended that "Premium Quality" steels be used. This will assure sufficient carbon content (>.3%) for TD treatment. Lower hardness of RC 44/48 on H-13 can be obtained at extra cost and time.
High Speed Steels

M-4

All of the above High Speed Steels are "under-hardened" during TD treatment, providing higher toughness. Higher hardness, if desired, is possible with "post hardening." This service adds cost and time and is quoted separately.

All of the above specialty steels have excellent dimensional stability during TD treatment, excellent hardenability during TD treatment, and can be "post hardened" to higher hardness, if required. This service adds cost and time and is quoted separately.
Cemented Carbides
WC
> 70
Excellent

Most Cemented Carbide grades have shown excellent results when TD treated. Substrate hardness of the carbide is not affected by TD treatment. Dimensional stability is excellent. We recommend carbide grades be at least 10% cobalt for best results.

* Rockwell "C" reading of substrate experienced after TD treatment.
