Steel 9ХС

Characteristics of steel 9XC 

  Grade 9XC steel contains many alloying additions that provide the desired characteristics and properties. In addition to the main components, there are silicon, calcium, chromium, carbon, sulfur, a total of 12 alloying and additional components. Due to increased elasticity, high strength, wear resistance and density, this type of steel is considered the best choice for making knives. 

Decoding the markup 

  Each type of steel has its own marking, which encodes the characteristics of the composition. The marking of steel 9XC has the following decoding: 

  * the number "9" indicates that the alloy contains 0.9% carbon; 

  * the letter "x" indicates that the steel contains chromium; 

  * the letter "c" indicates that silicon was added to the composition. 

  The presence of carbon increases the hardness of the material. Chromium is a universal component, it increases the possibility of thermal exposure of the alloy, makes it stronger and eliminates the risk of corrosion. 

Advantages of steel 9XC 

  9XC steel has unique technical characteristics that allow it to be used in the production of strong, elastic, wear-resistant parts with a high coefficient of resistance to bending. 

  In the 9XC alloy, the carbides are always evenly and correctly distributed in the cross-section, which improves the performance of the finished products, especially the threaded elements made from it.

  After annealing, it acquires another indisputable advantage - increased hardness and sensitivity to burning.

  It has high thermal stability. 

Chemical composition of steel 9XC 

  13 materials are used in the creation of 9XC steel, which, when combined in the right amount, provide qualitatively better physical, mechanical and operational properties. 9XC steel consists of: 

  * iron (Fe) - 94%; 

  * silicon (Si) - up to 1.6%, but not less than 0.9%; 

  * chromium (Cr) - up to 1.25%, but not less than 0.95%; 

  * carbon (C) - 0.9%; 

  * manganese (Mn) - up to 0.6%; 

  * nickel (Ni) - 0.35%; 

  * copper (Cu) - 0.3%; 

  * molybdenum (Mo) - 0.2%; 

  * tungsten (W) - 0.2%; 

  * vanadium (V) - 0.15%; 

  * sulfur (S) – 0.03 percent. 

  * phosphorus (P) - 0.03%; 

  * titanium (Ti) - less than 0.03 percent. 

  Percentages may vary slightly from manufacturer to manufacturer. Deviations should not exceed 1/10 percent, otherwise the properties of the resulting alloy may differ. 

  9XC steel is widely used in industry for the production of such products as: knives and other cutting tools, drills of various diameters and purposes, cutters for industrial and household equipment, distinguishing signs used in field work, equipment parts. Steel can be used in other areas as well, if the technical and operational characteristics meet the requirements for manufactured products. 

  Knives made of 9XC steel are often used in the food industry, hunting, tourism and other activities. The impressions of the experience are mostly positive. In general, the owners of 9XC knives are satisfied and note the high strength of the products, the long-term preservation of the initial sharpness after sharpening.
