Detailed

SK5 SK85 JIS Carbon Tool Steel

Introduce SK85 Sk5 steel

Sk85 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.

SK85 Sk5 steel appliction

It’s 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 (62-63 HRC), which makes sharpening a bit hard.

Toughness:

SK85 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
