YTL8 whats about that steel ?

YTL122 tends to be just like Cr12Mo1V(GB) in composition but what about YTL8 ? Is its composition the same as YTL122 and Cr12Mo1V(GB) ? If im not wrong it has 0.90 Vanadium, so its almost like real D2 right ?

I found some Chinese knife with that steel and i was thinking about trying it, the only problem i know nothing about that steel


Also sorry for my bad English.

i dont know anything either, but i did find this with a quick google search

Chemical Composition C Cr Mo W V Si

Based on YTL122 (AISI D2), EAST TOOL introduces Cr8 high-carbon cold-work steel, it has a feature of itself in composition and performance and strength and toughness near to high-speed steels.

Property:

• Carbide segregation is the most important quality target of high carbon ledeburitic steel. Both YTL8 and YTL122 belong to ledeburitic steel, but the carbide of YTL8 is finer and the state of distribution is improved thus YTL8 gets the higher toughness and plasticity.
• YTL8 uses the high-heat tempering to replace the low temperature tempering, which reduces residual stresses, decreases the possibility of angle rupture and craze during the patternmaking and improves the security of linear cutting and grinding.

Unique Characteristics:
Higher hardness (62-63 HRc) than D2 after heat treatment.

• Twice the toughness of D2 with superior wear resistance.
• Higher fatigue strength than D2.
• Smaller primary carbides than D2 protect the die from chipping and cracking.

62 - 63 HRC and hard to chip or crack ? It sounds too good to be true

Does not say anything about a blade being hard to chip or crack.
It all be hype. Just because the steel allegedly makes a "better" die does not mean it will make a "better" knife blade, or a better wrench, prybar, or any other tool, for that matter.

Actually, based on the 1% carbon (vs 1.5% in d2) - I believe it's easily twice as tough... that half a % of carbon is a huge deal.

This is why super tough steels like 3v typically hover around 0.8%. Read some posts by Larrin. (I'm not saying marketing hype is true either, fwiw, but I'd just rather try sticking to the science of it)

Depends on how good the heat treatment is. If it's China and low budget then likely didn't spend much time on the ht. Just sayin.

 

[H0kieengineer]

That chemistry should provide plenty if very hard carbides, but, if it is cast unfit and not powdered, they are going to be fairly large carbides. Should be a good steel if it has a good HT.

 

[Larrin]

There are a lot of these ~8% Cr series steels used in dies as an alternative to D2 when higher toughness is needed. Like DC53, for example.

YTL8？ You are asking question about PSRK‘s product?是在问骚浓对吗？

Then better try to find some stuff from EST (浙江一胜特)

这是一胜特的产品目录，你可以看到YTL8对应的是Cr8Mo2VSi

这也就是所谓的“国产DC53”。说实话，我对这种钢材一直不是很放心。
去油管看看https://www.youtube.com/channel/UCKZ1Tgw0dX2iP0CtAPKlk1Q这个人的测试吧。
重点和蝴蝶D2，农具，卡巴，冷钢VG-1做对比。
