Stainless steel is a kind of metal material widely
used in industries such as food, medical appliances,
automobile parts, and construction materials. It is
widely used because of it resistance to corrosion and
its strength and luster.
Lately, the demand of high strength and heat
resistance stainless steel for turbo charger turbine
housings has risen significantly.
High strength and heat resistance stainless steel is
grouped into hard-to-cut stainless steel which more
often provides high temperature occurring wear on
inserts, fractures and chipping on tools due to heat
and welding making high shear resistance than
general stainless steel.
The existing grades of M25 to M35 grade reaches the
limitation of improving tool life and cycle time in highly
unstable and interrupted machining with hard-to-cut
stainless steel.
Moreover, KORLOY recommends a new rising grade,
PC9540 for improving productivity in hard-to-cut
stainless steel milling.
The PC9540 which is an exclusive grade for M40
grade stainless steel maximizes chipping and fracture
resistance in medium to rough cutting and interrupted
milling due to its high toughness substrate. It also
allows stable machinability in high strength and heat
resistance stainless steel by applying the new rising
PVD oxide film with oxidation and heat resistance.
Therefore, the average tool life of the PC9540 is 50%
longer in hard-to-cut stainless steel machining than
the existing grade and it provides high productivity in
general stainless steel machining.
The 9540 is the latest grade providing solutions to
improve productivity and achieve stable stainless steel
machining.
Long tool life
- Increased resistance to breakage due to high toughness in the substrate
- - Long tool life in medium to rough cutting and highly interrupted machining
Stable machining
- - Increased oxidation and welding resistance with PVD oxide film
- Preventing built-up edge, notch chipping and unexpected breakage
Generally usable for stainless steel machining
- General stainless steel: ferritic, martensitic, and austenitic stainless steels
- High strength and heat resisting stainless steel: duplex, precipitation hardening, and heat resistance stainless steels
