Sk*5 Sk5 is a Japanese high-range Carbon
steel. After quenching and tempering, sk5 steel has
high hardness and wear resistance. SK5 high carbon steel is
used to make various tools which request high hardness and wear
resistance, such as the shape of the mold and the simple punch,
metal cutting tools, drilling tools, woodworking cutter,
countersink drills, axes, chisels, hand saws longitudinal and
fitter assembly tools, rivet die and other minor tools. We can
supply SK5 steel in hardened & tempered process and
annealing process.
SK*5 Sk5 steel appliction
Its used in a wide range of tools (Razor
blades, utility knives, scalpel blades, long edged tools,
cutting tools) due to its workability, hardenability, price,
and other features.

Edge Retention:
offers impressive edge, being carbon steel
with close to 1%, makes it very hard steel with great edge
retention.
Corrosion Resistance:
offers decent corrosion resistance, not a bad
one, but it must be taken care of to avoid future rust and
corrosion.
Wear Resistance:
Great wear resistance, thanks to the fine
grain and Carbon carbides.
Sharpness:
The rule says the harder the steel, the
harder to sharpen it, SK5 can get very hard (****3 HRC), which
makes sharpening a bit hard.
Toughness:
SK*5 Sk5 is very tough steel with great
impact resistance, the steel offers a great balance between
hardness and toughness at the cost of corrosion
resistance
