56Si7 steel ?

[P_A_S_1]

Anyone familiar with this steel? I just brought a k sabaiteir carbon and this is the steel they use taken to about 55rh. The best I can find is that it has high silicon and is something like 5160.

Ok, thanks. I'm guessing 'very pure' is a good thing and high silicon is a plus too.

It’s like 9260 or S5. Shock resisting steel with high toughness.

Is it primarily a construction steel?

No it isn’t used in construction, those steels are completely different. You can read some of the applications here: http://www.crucible.com/eselector/prodbyapp/tooldie/labelle.html

Thanks for the link and info. Time will tell what I think of it for a cooks knife compared to my Zwilling. The Zwilling is pretty tough as I've used to crack open lobsters and coconuts, this should be less prone to breaking under hard use. Edge holding in comparison is what I'm curious about, hope it's better. I'll put the pdf below of the steel which the maker sent me if anyone's interested.



Ok, I can't seem to get the attachment to work, no clue why.

that should be the exact link for the info...

looks like plain 1060 with a big shot of silicon, in the range of 1.6%-2.0%, which makes it less forge friendly

I wouldn't expect much in terms of edge retention, but it should be very tough
