Annealing: Heat to 1650?F (900?C), hold 2 hours, slow cool no faster than 25?F (15?C) per hour to 1100?F (595?C), then furnace cool or cool in still
Quench: Air or positive pressure quench (2 bar minimum) to below 125?F (50?C), or salt or interrupted oil quench to about 1000?F (540?C), then air
Austenitize 1950?F (1065?C). Quench to below 125?F (50?C). Double temper at 600?F (315?C) 2 hrs. minimum each temper. Cool to hand warm between
Annealed Parts: Heat to 1100-1300?F (595-705?C), hold 2 hours, then furnace cool or cool in still air. Hardened Parts: Heat to 25-50?F (15-30?C
Hardening Preheat: Heat to 1550-1600?F (845-870?C) Equalize.
Stress relief to prevent warpage: 650°C-680°C hold for 3-5h let cool slowly in oven.
The grade itself is a hypereutectic steel and with the carbon content of around 1% capable to deliver 66HRC easily, after the quench.
When tempering at 400-750?F (200-400?C), freezing treatments may be necessary to minimize retained austenite.
Carbon V chemical composition is equivalent to the SAE standard for construction steels 50 100 (UNS G50986 or the German grade 1.3501)
Now since you didn't forge or fire weld it, meaning you do stock removal only, you can expect the steel to be annealed correctly.
Flextest: Check sharpened edge with flex test in case it fails add 10°C to the tempering temperature and try flex test again after 1 h tempering
Note: avoid tempering temperatures higher than 200°C because the steel will loose to much of its potential and between 200 and 300°C the is a area of
A freezing treatment - may be used between the first and second tempers. Freezing treatments help to attain maximum hardenability and must always be
corrosion resistance. Size Change: +0.05 to +0.10% when fully martensitic. The presence of retained austenite may reduce the net growth.
