Wear tests of steel knife blades - Verhoeven, Pendray, Clark March 26, 2012 03:47PM |

Verhoeven, et. al.
A study is presented on the relative wear rates of two carbon steels, a Damascus steel and a stainless
steel, using the Cutlery and Allied Trades Research Association (CATRA) of Sheffield England cutting test
machine. The carbon steels and stainless steel were heat treated to produce a fine array of carbides in a
martensite matrix. Tests were done at hardness values of HRC = 41 and 61. At HRC = 61 the stainless steel
had slightly superior cutting performance over the carbon steels, while at HRC = 41 the Damascus steel
had slightly superior cutting performance.

Verhoeven, et. al.
(1) Use of the CATRA machine with their standard board to evaluate
cutting performance of steel blades is best carried out at small
stroke numbers.
(2) These experiments support the view that martensitic stainless
steels optimized for hardness and fine carbide distributions
have slightly superior cutting performance than high carbon
steels.
(3) At a hardness of HRC = 61, 52100 steel has a better cutting performance
than 1086 steel and both are generally better than
Damascus steel. However, at HRC levels of 41 obtained with
fine pearlite or quenched and tempered conditions the Damascus
steel has slightly superior cutting performance than high
carbon steels.

Here is my 2 SQ 52100 blades baton & reverse-chop toughness tests video. 62rc & 63rc; 10dps; 0.01 & 0.012 behind edge thickness. I gather ht params for my next chopper.
video: [youtu.be]
edit: wow, just finished reading Me2's excellent thread on BF. 2012 is pre-dated my knife making rabbit hole.

It is interesting however that most often Elmax is seen in the rank of S30V, S35VN and 154CM

Somehow I have a feeling that only a limited audience would accept this, even with the test results provided, on a larger forum.

The advantage of ELMAX really starts once it's taken over 60 HRC getting into that 61-62 HRC range, that's speaking about edge retention. There is a rather large difference in performance from that 59-60 range to 61-62 range, that's having tested knives in ELMAX from 58.5 HRC to 62 HRC.

Jim there is no significant difference in materials properties in Elmax in that range, neither in resistance to deformation/rolling, nor in wear, there could be no significant difference in edge retention which is thus dependent on those properties.
