Many knife manufacturers use versions of Asus6-10, Asus440a, and Asus440c, which also are all Aicihi steel. Many were modified to name others, sometimes such as molybdenum vanadium steel. AL-158; BRD4416 stainless steel; X55CrMoV14 or 1.4110 Swiss Army knife Inox blade steel used by Victorinox. 80CrV2 is commonly known as Swedish Saw Steel.
In 2009, Crucible Steel introduced an update to CPM-S30V to meet the needs of renowned knife maker Chris Reeve that they called CPM-S35VN. The addition of 0.5% Niobium, and reductions in both Carbon (from 1.45% to 1.40%) and Vanadium (from 4% to 3%) produced an alloy with 25% increase in measured Charpy V-notch toughness over S30V (Crucible claims 15-20% improvement).
440C (UNS designation S44004) is a martensitic 400 series stainless steel, [1] and has the highest carbon content of the 400 stainless steel series. It can be heat treated to reach hardness of 58 to 60 HRC. It can be used to make rolling contact stainless bearings, e.g. ball bearings and roller bearings. It is also used to make knife blades.
In stainless versions, this technique offers a practical and visible advantage of a superb cutting edge of modern Japanese knife steel, with a corrosion-resistant exterior. In professional Japanese kitchens, the edge is kept free of corrosion and knives are generally sharpened on a daily basis.
Knife retailer Cold Steel markets a variety of knives that use VG-1. [5] Cold Steel claims that VG-1 has better sharpness, edge retention, point strength, shock and strength characteristics than 440C , VG-10 , or ATS 34 stainless steels, though any of those alloys may be better than VG-1 in individual categories.

A common example is COR-TEN. Control-rolled steels: Hot rolled steels which have a highly deformed austenite structure that will transform to a very fine equiaxed ferrite structure upon cooling. Pearlite-reduced steels: Low carbon content steels which lead to little or no pearlite, but rather a very fine grain ferrite matrix. It is strengthened ...
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
Material selection is often benefited by the use of material index or performance index relevant to the desired material properties. [2] For example, a thermal blanket must have poor thermal conductivity in order to minimize heat transfer for a given temperature difference. It is essential that a designer should have a thorough knowledge of the ...
