what steels and why

[Mike Davis]

Awesome stuff guys!!! I had no idea you could make powdered steel into damascus, Learn something new everyday. Thanks Devin for leading us into unfamiliar territory

Devin, I can't find any information about your PM stainless. could you compare( Edge holding, Toughness, Edge stability, Sharpenability) between S35VN & DT PM stainless. thanks!!

who's heat treating the s35vn? need to factor that in too. different heat treatments result in different numbers.

I have used both and imo can say in edge holding, toughness, and stability,the DT pm stainless wins. On sharpenability they are very similar.

DT will do the heat treatment for s35vn & PM stainless..

Rating some stainless steels.

Steel type Edge holding Toughness Edge stability Sharpenability Stain resistance Overall rating
AEB-L...........6.................4..............10... .............10..................8................ .....7.6
Stainless PM.8..................4..............7.5.......... .....8...................8.5...................7.2
CPM 154.......7.5...............3..............6.5.... ...........7...................8.................. ....6.4
440-C...........7.5...............2..............4.5.. .............7...................8.5.............. .....5.9
VG-10..........6..................3..............6... ...............7...................8.5............ .......6.1
19C27..........6.5...............3.5............6. 5...............7...................7.5........... ........6.2

Some categeries may not be equaly important making the overall rating inaccurate. These numbers are based on our experiance in use and from charts from other researchers. I ran these steels by Larrin and averaged the numbers between us. Others may come up with slightly different numbers, but we feel that these should be close.

More to come.

This thread is awesome! you make stunning damascus patterns Devin
How would you rate 15n20 as a single steel?

Tried to edit but... the 15n20 question should be in this category of course

[DevinT]

15N20 has good toughness but not very good edge holding compared to other cutlery steels. Toughness=5, edge holding=3.5, edge stability=9, sharpen-ability=9, stain-resistance=2, overall= 5.7

[Sabaki]

thank you for your answer!

[Sabaki]

Think i have read somewhere that 15n20 has a 0.11% Cromium content to it, i dont think so but is there?

Is there any difference between 52100 and UHB20c15? if so, do you have a rating as well?


thanks in advance!
