Diameter (mm)6.5-8081-250
Length (mm)2000-60002000-6000
Tungsten-molybdenum high speed steel with excellent toughness and cutting properties,
for a wide variety of uses.

Heat Treatment
770 to 840°C (1418 to 1544°F)
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to
. 600°C (1112°F), further cooling in air.
Hardness after annealing: max. 280 HB.
Stress relieving
600 to 650°C (1112 to 1202°F)
Slow cooling in furnace; intended to relieve stresses set up by extensive machining,
or in complex shapes.
After through heating, hold in neutral atmosphere for 1 - 2 hours.
1190 to 1230°C (2174 to 2246°F)
Oil, salt bath (500 to 550°C (932 to 1022°F), vacuum.
Upper temperature range for parts of simple shape, lower for parts of complex shape.
For cold working tools also lower temperatures are of importance for higher toughness. Soaking time after heating up the whole section of a work piece 80 seconds minimum
is required for dissolving sufficient carbides.
Maximum soaking time 150 seconds to avoid detriments by over soaking.
In practice instead of soaking time the time of exposure from placing the work piece into
the salth bath after preheating until removing (including the stages of heating to the specified surface temperature and of heating to the temperature throughout the whole section) is used. 
Vacuum hardening is also possible. The time in the vacuum furnace depends on the
relevant work piece size and furnace parameters.
Slow heating to tempering temperature immediately after hardening/time in furnace:
1 hour for every 20 mm of work piece thickness, but not less than 2 hours/ air cooling
(minimum holding time: 1 hour).
1st tem pe ring and 2nd tempering to de sired working hardness.
Average obtainable hardness values are shown in the tempering chart.
3rd tempering for stress relieving, 30 - 50°C (86-122°F) be low highest tempering temperature.
Obtainable hardness after tempering: 64 - 66 HRC.

JIS Skh51 High Speed Tool Steel Round Bars

JIS SKH51 is suitable for cold work applications, for example tools for punching, forming
and pressing, etc.. SKH51 possesses an admirable combination of wear resistance,
toughness and compressive strength. This combination of properties makes it superior
to many high alloyed cold work steels.

Quality Assurance
Below inspection will be done in the production.
(1) ray detection---RT;
(2) ultrasonic testing---UT;
(3) Magnetic Particle Testing-MT;
(4) penetration testing-PT; 
(5) eddy current flaw detection-ET
