STEEL PROPERTIES

Superior hardening performance

KCRX having the superior hardening performance,
wide hardening temperature range from between 850°C ~ 1030°C.  KCRX may be hardenened in the same conditions as the SKD11 and SKS3.
Offers as high hardness as 60HRC in the hardening conditions with gas cooling at 1030°C

Superior Machinability
KCRX having two or more times as high machinnability as the SKS3
Good machinability after hardening and annealing facilities repair machining

Superior tenacity
KCRX have better tenacity than the SKS3 reduces chipping and cracks

Wide application range
KCRX applicable to molds, parts, jigs, tools, and other products as general-purpose cold-tool steel

APPLICATION
Total hardening: Various cold molds, die plates, stripper plates, and other mold parts, as well as various jigs andn tools
Flame-hardening: Cold molds, such as flame-hardened blanking dies, drawing molds, and blending molds

HEAT TREATMENT (Flame hardening of the edge of tool)

Working EnvironmentIndoors where the constant brightness is kept
Pre-Heating200-300C (if too high, there is a danger preventing sufficient hardness)
HeatingTo be heated until it turns into light red color (aim 950C) then shift the heating area in turn, controlling the torch feeding speed
TemperingNot necessary but if tempering of 150-200C is done, the toughness gets improved
