The grade itself is a hypereutectic steel and with the carbon content of around 1% capable to deliver 66HRC easily, after the quench.
tecnica
Carbon V chemical composition is equivalent to the SAE standard for construction steels 50 100 (UNS G50986 or the German grade 1.3501)
tecnica
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
tecnica
The 50100 "Carbon V" is rated as a construction steel, means unlike its high quality brothers out of ball bearing construction e.g. 52100, it has the
tecnica
So the treatment after machining would be:
tecnica
Protect surface from decarburisation at all steps of the process!!
tecnica
corrosion resistance. Size Change: +0.05 to +0.10% when fully martensitic. The presence of retained austenite may reduce the net growth.
tecnica
Hardness check: file should be sliding over the edge wo getting grip
tecnica
2nd Temper: 150°C-200°C depending on the hardness you want
tecnica
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.
tecnica
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
tecnica
A freezing treatment - may be used between the first and second tempers. Freezing treatments help to attain maximum hardenability and must always be
