Aisi O1 Steel Round Bar Sheet Plate Din 1 2510 Jis Sks3 - China

o1 steel is used as a material of tough parts.

such as punches, knock-out pins, cams, and of course, knife blades.

and 1.2510 steel is mainly used for short-run tooling for cold forming dies, blanking dies, and cutting tools operating at ambient temperature.

typical applications for o1 tool steel are blanking, forming, and trim dies, gages, slitting cutters and etc.

o1 steel round bar sheet plate heat treatment

stress relief of unhardened material

heat slowly to 1250° f.

soak for two hours per inch of thickness at heat.

slow cool (furnace cool if possible) to room temperature.

hardening

critical temperature:

ac1: 1350°f ac3: 1400°f

(732°c) (760°c)

ar1: 1295°f ar3: 1240°f

(703°c) (671°c) preheating

heat at a rate not exceeding 400°f per hour (222°c per hour) to 1200-1300°f (649-704°c) and equalize.

austenitizing (high heat)

heat slowly from the preheat to 1475-1500°f (802-816c) soak for 30 minutes for the first inch (25.4 mm) of thickness, plus 15 minutes for each additional inch (25.4 mm).

quenching

oil quenching to a temperature no lower than 150-125°f (66-51°c).

note o1 steel is prone to quench cracking, especially if there are significant changes in section thickness and sharp internal corners.

the oil quenching should be performed so that the heat removal is as uniform as possible in all areas of the part being quenched.

be sure to remove the part from the oil before the temperature drops to ambient temperature.

hot oil at a temperature of 300 to 400°f (149-204°c) is recommended.

tempering

temper immediately after quenching.

do not allow the part to cool below 125°f (51°c).

the typical tempering range is 350 – 400°f (177 -204°c).

hold at temperature for 1 hour per inch (25.4 mm) of thickness, 2 hours minimum, then air cool to ambient temperature.

to minimize internal stresses in cross sections greater than 3 inches (76.2 mm) and to improve stability in parts that will be edm’d after heat treatment, a soaking time of 4 to 6 hours at the tempering temperature is strongly recommended.

cryogenic treatment

refrigeration treatments should typically be performed after the temper, and must be followed by a second temper.

annealing

annealing must be performed after hot working and before re-hardening.

heat at a rate not exceeding 400°f per hour (222°c per hour) to 1425 -1450°f (802-816°c), and hold at temperature for 1 hour per inch (25.4mm) of maximum thickness; 2 hours minimum.

then cool slowly with the furnace at a rate not exceeding 50°f per hour (28°c per hour) to 1000°f (538°c).

continue cooling to ambient temperature in the furnace or in air.

the resultant hardness should be a maximum of 212 hbw.
