SKS3 material toughness, high hardness, air-cooled high-chromium tool steel hardened, the hardness of steel than the SKD and toughness.
Features Uses
● pure steel; ● ball softening annealing organization easy cutting;
● high quenching hardness;
Tempered with good dimensional stability.
Widely used to make the thickness of not more than 8mm of stamping die, stamping die, bending die, finishing mode;
● used to make the gauge, measuring tools, woodworking tools and lathes thimble, etc.;
● for the system to guide bushing, thimble, die, wire needles.
Heat treatment
Quenching: first preheated to 550 ℃ ~ 650 ℃, and then heated to 800 ~ 850 ℃ in oil hardened.
Tempering: heating to 150 ℃ ~ 200 ℃, to stay at this temperature and then cooled in still air quenching.
Hardness: HRC60 ℃ above
Annealing: Heat to 750 ~ 800 ℃, the temperature in this stay one to three hours in the furnace allowed to cool gradually.
