High chromium japanese 440B stainless steel for knives,swords,blades

 

AUS-8 Japanese stainless steel, roughly comparable to, if not slightly better than 440B (AUS-6, .75% carbon)

Introduction

Grade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment. These properties make this grade suitable for applications such as valve components and ball bearings. Grade 440A and 440B stainless steels, on the other hand, have similar properties - except for a slightly lower percentage of carbon in grade 440A.
