Ranking steel properties
Ranking steel properties
Hello forum,
I was wondering if there is some kind of ´ranking-schematic' of different steel properties in where you can see what steel has higher edge retention than the other, thougness, wear resistance etc etc. I know so properties depend on hardening, edge-angle, temepering etc, but some can be put in line (I guess... :o )
All (important) properties next to eachother so you can use it to chose a right steel for your own purpose. Is such a schematic somewhere available, or do we have to make one our own :rolleyes: ?
Cheers,
T.

Well Ankerson did an edge retention list over on bladeforums http://www.bladeforums.com/forums/showt ... -quot-rope
it's pretty good, lots of work went into it and I like it because it uses actual production steel, not just just a ranking by data sheet info.
As for toughness...I haven't seen anything similar.

There are charts like these available at various places. http://www.latrobesteel.com/technical_a ... arison.cfm
Pick a class of steels , click the link and there's your chart. There are lots more around.

It's easy to find charts where companies compare their own steels to each other. The tricky thing would be to find cross company comparison. I'd just try to make my own using existing data if I were you. A lot of manufacturers like to compare their steels to 440c as a benchmark. Here's where I got this chart: http://www.knifeblog.com/knife-steel-comparison-charts/

Niagara speciality steels has a lot of good information on their website. They supply steel to people and companies after rolling it and cutting it down to thickness more useful to knife manufacturers and other companies.
They are good folks.

Interesting chart. I am quite surprised to see 440C with better wear resistance and toughness than 154CM and D2The Mastiff wrote:Niagara speciality steels has a lot of good information on their website.

It's one I tend to disagree with. 154cm is pretty tough. D2 as well. 440C isn't fragile or anything but I believe it's below the others in toughness. Looking at the graph and charpy V notch in this data sheet for S30V has different numbers than the other one. This is more what I thought. 440C does have a lower carbide volume than 154cm and that usually signifies a tougher steel but not always. CPM 154 is even tougher than regular 154cm. CPM D2 is tougher than regular D2. When it comes out Carpenters 40CP ( powder steel 440C) will likewise help it.Interesting chart. I am quite surprised to see 440C with better wear resistance and toughness than 154CM and D2
Carpenter S30V page has this info:http://www.crucible.com/PDFs%5CDataShee ... 202010.pdf
Anyway, the graph says it all here. Latrobe calls 154cm 14/4 so you cal look it up on their charts too and see what they say.

They have 154cm being tougher than 440C, which is tougher than D2.
I guess individual blades and how they are ground, and the heat treat they recieve can easily change numbers in the real world. Charpy I'm not so sure. I think the sizes, grinds and angles are supposed to be the same. Hardness can't always be the same as different steels reach their peak at different hardnesses ( and with different temp's in the heat treat)

kennethW did something close to what you want (toughness isn't included) and put it up on BF recently

It's worth going through his whole post; the chart is really a cliffnotes version.
