High carbon chrome knife balde steel Aus- 10


AUS-10 Steel


Has 1.1% carbon. This steel is comparable to 440C

It has more vanadium and less chromium than 440C so it is slightly tougher.but also a little less rust resistant.


9Cr13MoVCo /9Cr13CoMoV


A Chinese made High-carbon stainless steel equals to AUS-10 with increased levels of cobalt added for greater edge retention. Offers a higher level of corrosion resistance at a great value.

Chemical composition of knife steel   The chemical composition of a knife steel must be balanced, not over alloyed, and precise.
The specification tolerances must be tight in order to secure a high consistent quality in the finished knife. 
Here is a breakdown of the most common elements in knife steel:
Carbon (C) The main driver for hardness. Too much carbon however makes it more difficult for the material to produce martensite 
and thereby deep freezing is necessary to achieve high hardness. 
The hardness is related to the amount of carbon dissolved in the steel matrix. 
By tying up chromium into carbides the carbon is indirectly decreasing corrosion resistance.
Chromium (Cr) The main driver for corrosion resistance. 
The corrosion resistance achieved is related to the amount of Cr dissolved into the steel matrix and not related to the
nominal composition. Cr is also the main driver for carbide formation.
Molybdenum (Mo) Drives carbide formation and has a small influence on hardness and corrosion resistance in martensitic stainless grades.
Vanadium (V) A strong carbide former. The vanadium carbides are also very stable and do not dissolve during heat treatment.
Nitrogen (N) Hardness driver like carbon but does not have the same negative effect on corrosion resistance. 
Nitrogen is not commonly used in these applications since it is difficult to achive significant levels of nitrogen in 
conventional steel production.
Sulphur (S) Forms sulphide inclusions which have a negative influence on the initiation of pitting corrosion.
Manganese (Mn), Phosphorus (P) and Silicon (Si) These elements make no significant contributions. The general rule is to keep these as low as possible.
