Alleima 14C28N – the most advanced, high-tech knife steel containing Nitrogen! Patented by Alleima Material Technology – the leader in knive steel manufacturing. Thanks to its ideally fine structure it guaran - tees high hardness, long life edge retention, and excellent corrosion resistance!
The new 14C28N, recently patented by Alleima Material Technology is the most advanced one. Taking profit from the experience of Alleima SMT on the razor blades steel,
“the most advanced knife steel…”
Only a few stainless sheets of steel containing Nitrogen is available for knifemakers. The presence of Nitrogen in the 14C28N permits the increase of the hardness without a high level of Carbon and thanks to that the risk of getting long or oversized carbide is limited.the Alleima 14C28N offers an ideal mix between a very dense presence of spherical second - ary carbide, together with excellent corro - sion resistance. The long-life edge retention can be easily obtained together with easy resharpening work. This is another very interesting performance of this grade. Nitrogen is a very interesting element to add to knife steel. This element, similarly to carbon, is a hardness driver. The presence of nitrogen leaves more free chromium in the alloy. Nitrogen in the knife steel contributes to its hardness in the way carbon does in the alloy. N substitutes C for higher hardness. The technology needed to introduce this element is not so common.
Alleima SMT is one of the few companies able to achieve this performance, thanks to the experience in complex metallurgical structures. The blades produced by the Alleima 14C28N have a very good corrosion resistance despite the high level of Carbon, without diminishing the hardness or the durability of the cutting edge. It is not so easy to find the right process to differentiate between various alloys for knifes blades. The tests or protocols used for typical stainless steel are not applicable. For austenitic stainless steel, it is possible to classify the different grades thanks to the PRE formula where nitrogen is an important factor. We can observe that nitrogen counts 16 times more than chro - mium and 5 times more than molybdenum. Of course, this formula cannot be used for the martensitic grades but it can give an idea of how nitrogen influences the knife steel. Another interesting feature is the fact that such corrosion resistance is obtained preserving a very high level of hardness as - in general - these performances are opposite
