KI. tffte^ ho k ^ Steel alloys containing, in addition to the usual components, silicon and chromium, are known. They are used for the production of jiatoo tools and structural steels. The invention aims to achieve a far-reaching improvement of these steel alloys and their physical properties. This goal is achieved by adding nickel, cobalt or tungsten. The components of the new isitope vary within the following limits: 0.10 - 1.00°/o C Q.15 - 1.00°/o Mn 1.00 - 2.50% Si 0.30 - 2.50°/o Cr 0.40-6.00°/o Ni Nickel can be completely or partially replaced by cobalt or tungsten and cobalt. As a specific example of an alloy, according to the invention, the following composition is given: 0.50% C, 0.30% Mn, 1.70°/0 Si, 0.70°/0 Cr and l°l0Ni. The new steel sieve is particularly dirobnoziaiinil&tym uistiroijein, it is similar to the arrangement of steel and high-speed steel blades with great tungsten strength. The significant properties of this alloy are that this steel alloy meets far-reaching requirements in its natural form; and therefore, in many cases, it is not necessary to improve it. The new alloy is particularly suitable for gears, gear springs, crankshafts, barrels, tools, namely for impressions and mandrels for pulleys, arrow breaker plates, armor plates, etc. It should be combined with a lightly watered alloy Alloyed alloys, i.e. 0.70% Cr and 1% Ni, are much better for protective alloys than, for example, silicon-free alloys containing 1.5% Cr and 4.00% Ni. The protective alloys of the new steel can be used in the as-rolled condition without further heat treatment. Therefore, this alloy is particularly suitable for protective alloys for aircraft, only 1-2 mm thick, which cannot be hardened. For these alloys, alloys containing, in addition to chromium, 4-8% nickel and 1-2% tungsten have been used so far in order to achieve sufficient quality in the rolled alloy. The new steel exceeds the above alloy composition. New steel in a refined condition can also be used for impressions and drawing pins. New steel is also very suitable for this purpose because it has a low wear rate and therefore approaches the quality of high-manganese steel. Moreover, it retains its strength and hardness even when heated. This is important, especially for certain purposes. Even better results are obtained if the nickel is replaced completely or partially with cobalt. When using steels for blacksmith tools, nickel is replaced with tungsten or cobalt and tungsten.
