New heat treatment process - EP process
Process features:
Maintain a high hardness (overall 61HRC) at the same time, at the same time have excellent toughness, elasticity. And significantly improve (40%) wear resistance.
Process Scope:
Kitchen knife, small straight, straight and so on.
First show is the important parameters: long diameter (thick) ratio of 37.
Can do the limit of 60 degrees. If converted into a 350mm long, 6mm thick has been opened V knife, then, that is, you can limit the break to 90 degrees or so.
Indicating that this process, there are still excellent overall performance.

Equivalent conditions Belt grinding test comparison, the difference under different heat treatment process. The camera did not look obvious. Maybe the camera is too bad ~
Why the hardness increase 1HRC, wear will increase a lot of it? See below
From the metallographic point of view, the bulk of a large number of small carbides and ultra-fine carbides. These carbides are very hard and very small, helping to improve abrasion resistance. On the other hand, it is to enhance the retention.
The second advantage of ultra-fine carbides is to improve the "cut". What is the feeling? Through discussion, I think it is a feeling very sharp, cutting very smooth feeling. Ultra-fine carbide in the edge of the mouth, the effective increase in the cut of the object "cutting, planing, friction." For example, it is like a saw blade with a missing tooth and a saw blade.
The third advantage is that large pieces of carbide can effectively block the cutting edge of the impact of the development of the impact of crack, but the general abrasive is difficult to effectively high alloy carbide grinding, so many carbides were abrasive washed in the polished The Ultrafine carbides can be fortunate to preserve because of their very small size. The future will maintain a good upgrade. Of course, if the conditions permit, or buy a good abrasive, so that the larger carbide also preserved it.
