Hello there 
I slowly thinking about to start making slipjoint knives and I have some questions.
I think about to use made in Poland, Low-Alloy Steels like: ( Because I'm from Poland
)
NC6 (1.2063)
C: 1,30-1,45% | Si: 0,15-0,40% | Mn: 0,40-0,70% | Cr: 1,30-1,65% | Mo: max. 0,20% |
Ni: max. 0,35% | V: 0,10-0,25% | Cu: max. 0,16% | S: max. 0,030% | P: max. 0,030%
NCV1 ( 80CrV2)
C: 0,75-0,85% | Mn: 0,30-0,60% | Si: 0,15-0,35% | Cr: 0,40-0,70% | V: 0,15-0,30%
N8E / 1.1525 / W1-8 1/2A | N9E / 1.1830 - [%] - that steel have hamon
C: 0,85-0,94% | Si: 0,15-0,30% | Mn: 0,15-0,30% | Cr: 0,15% | Ni: max. 0,2% | S: max. 0,025% | P: max. 0,025%
And 50HF / 1.8159 (6150) for springs: - tempered to 45HRC
C: 0,46-0,54% | Si: 0,15-0,40% | Mn: 0,50-0,80% | Cr: 0,80-1,10% | Ni: max. 0,40% | V: 0,10-0,20% | S: max. 0,03% | P: max. 0,03%
Those steels will be ok to use in Slipjoints?
And how people in US would see those steels? ( I don't have access to US made steels)
And why I'm asking?
Because this month I will get nice small knife kiln 230V 1 Phase 2,7kW power, max 1100*C (made in '80 times but still working and this is "muffle" type) and I will be finally able to HT my knives by myself
( in this kiln I'll be able to put only 3 knives at the same time in this kiln)
And because of this I also will start making knives not only from M390/Elmax/N690/K390 but also from mentioned above NC6, N9E/N8E, NCV1, 50HF (small bushcraft knives etc )
This type of kiln ( but in better shape )
Mostly because this will begin to be cost effective.
For now I pay for HT of one knife from M390/Elmax/K390/N690 about 8-10$.
And I could pay for HT of one knife from carbon/low-alloy steel also 8-10$ ( not very cost effective)
With my own kiln, I will don't even pay this much for a power to harden and temper 10 knives... ( and 100$ is safe in the wallet)
And then I have a kiln, and I can start learning how to HT knives before buying Industrial grade knife kilns.
2 kilns with chamber 200mm x 150mm x 450mm 4,5kW power in 3 Phase with IZO Smart Heat Control (on PLC components with touch screen). Probably I will be able to buy them, this year.
Before that I will learn how to HT on this small old guy
