Now quite common is "stainless" steel type 40Ch13, 40H13NV. These structural steel is now at least "favorite" among the artisans, hundreds of whom work on each TVET or giant factory. Some indestructible virtuoso in the quenching of such steel have really good results, reaching a hardness of HRC 56-58 at a satisfactory elasticity. Of similar steel making and cutlery. After reviewing the data table, we see that it is the closest analogue steel 420 (Except that the manganese content is slightly higher).
Despite the fact that the steel is stainless steel, in reality, it is susceptible to corrosion, especially in hostile environments or in low-quality polishing. Less corrode steel 95H18, which contains 18% chromium and the composition of the almost "falls short" to 440C (closer to 440V). This is a really great steel and, of course, more expensive. However, the soliciting of such properties is possible only if careful observance of forging and heat treatment technology. Today, only a solid, well-established firms can provide such conditions of heat treatment - heating in vacuum furnaces with high-precision control temperature, long vacation, cryogenic treatment (exposure at low temperatures for very small grains). But the craftsmen, not observing all the subtleties of process technology, will not be able to get good results and it turns out that the quality of the knife from 95H18 no better than those made of steel and tempered 40Ch13 master virtuoso. Of this steel make some responsible products plants in Russia. Referred to as "commando steel", from which may be made "knives intelligence" of the Soviet army.
I have seen such a knife. His arm was literally izmochalena of misses when throwing at a target, and the blade is slightly blunted at the tip, and then only because, as the owner of said blade at a miss, he constantly found himself in a concrete wall. 65H13 steel (similar to the Swedish 13S26) at a good tempering - one of the most suitable for a hunting knife materials, since the hardness of HRC 54-56, it is enough resilient and durable.
