DIN 1.3265 High Speed Steel | S18-1-2-10 | SKH4
DIN 1.3265/S18-1-2-10 high speed steel manufacturers and suppliers, supplied in round rods,flat/square bars,plates,sheets,wire and blocks.
DIN 1.3265/S18-1-2-10 Steel is a Tungsten-Cobalt high-speed tool steel which contains 8% Cobalt. The high temperature performance and toughness is better than DIN 1.3255 HSS. This kind of material also has high abrasion resistance and good cutting performance which is used for s turning tool,cutter,millin cutter,drill,broach,etc.

Heat Treatment For DIN 1.3265 HSS
The annealing temperature of DIN 1.32465 is generally between 850-910°C.Heat the temperature to 850-910°C at a rate of no more than 220°C per hour.Keep at the temperature for one hour per inch of thickness(at least two hours).
According to the cooling method, it is divided into softening annealing and isothermal annealing.
For Softenig annealing,it should be cooled to 500-600°C at 20-30°C/h and then furnace cooled.Hardness below 285HBW.
For isothermal annealing,it should be cooled to 740-760°C first, then kept for 2-4h, and then cooled to 500-600°C for slow cooling.Hardness below 285HBW.
- Hardening & Tempering For DIN 1.3265 HSS
1.Preheat DIN 1.3265/s18-1-2-10 HSS slowly to the temperature of around 850°C with a rate of 24mm/s
2.Heat to the final hardening temperature of 1280-1330°C with a rate of 12-15mm/s,and make sure the material must be heated through.
3.Quench in the warm oil,and then complete the quench in air.(care must be taken at this step)
4.Heat uniformly to the required tempering temperature
5.Withdraw DIN 1.3265/s18-1-2-10 HSS from the furnace and cool in air
6.The general tempering temperature is 560-590°C which makes the material above 64HRC.
7.DIN 1.3265/s18-1-2-10 High speed steel is also suitable for vacuum hardening
8.Triple tempering is strongly recommended.
