content of around 1% capable to deliver 66HRC easily, after  the  quench.
V chemical composition is equivalent to  the  SAE standard for construction steels 50 100 (UNS G50986 or
SAE standard for construction steels 50 100 (UNS G50986 or  the  German grade 1.3501)
avoid tempering temperatures higher than 200°C because  the  steel will loose to much of its potential and between 200
loose to much of its potential and between 200 and 300°C  the  is a area of low toughness (blue brittleness)
 The  50100 "Carbon V" is rated as a construction steel, means
out of ball bearing construction e.g. 52100, it has  the  lowest standard for cleanliness (sulphur, phosphorus),
 the  treatment after machining would be:
surface from decarburisation at all steps of  the  process!!
Size Change: +0.05 to +0.10% when fully martensitic.  The  presence of retained austenite may reduce the net growth.

check: file should be sliding over  the  edge wo getting grip
Temper: 150°C-200°C depending on  the  hardness you want
weld it, meaning you do stock removal only, you can expect  the  steel to be annealed correctly.
sharpened edge with flex test in case it fails add 10°C to  the  tempering temperature and try flex test again after 1 h
freezing treatment - may be used between  the  first and second tempers. Freezing treatments help to
