一些关于OU-31钢的资料 (Credit goes to Huugh & nozh2002 of BF).
Distributed by KYORITSO KOZAI
Produced by Nippon Koshuha Steel.
Micro fine steel embodies what many knife-makers have long wanted. It
is a steel developed by seeking after the bounds of quality of knife steel
with "homogeneous", "fine" and "clean" microstructure, using carefully
selected materials, and joining our comprehensive technologies.
Features
1. High hardness equivalent to M2: HRC64.
2. Better machinability than M2 or D2. Good workability by dispersing
fine carbide
3. Toughness more then 3 times higher than that of D2, achieved by
compounding special alloy and dispersing carbide.
4. Unrivaled wear resistance achieved by deposition of dense special
carbide.
5. Outstanding heat treatment properties. Hardening temperature
same as that of 13Cr and 18Cr stainless steels.
6. Sharpness equivalent to that of Japanese swords but MICRO FINE STEEL
does not break or bend, and cuts well for a long time.

From Jeff Hall post:
"It is a Japanese steel with .9 Carbon, 8.5 Cr, 2 Mo. Also has a sprinkle of Vanadium and a dash of (3%) Cobalt." |
