[4] [5] It contains a moderately high carbon ratio of approximately 0.46% which gives it a good compromise between high hardness and corrosion resistance for many applications. [6] [7] [8] It is also relatively inexpensive to produce. X46Cr13 is a basic steel without molybdenum, nitrogen or vanadium.
The reason for the limited use of high carbon steel is that it has extremely poor ductility and weldability and has a higher cost of production. The applications best suited for the high carbon steels is its use in the spring industry, farm industry, and in the production of wide range of high-strength wires. [10] [11]
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.

Stainless steel is an iron-carbon alloy with a minimum of 10.5% chromium content. There are different types of stainless steel, containing different proportions of iron, carbon, molybdenum, nickel. It has similar structural properties to steel, although its strength varies significantly.
To emphasize the point, consider the issue of choosing a material for building an airplane. Aluminum seems obvious because it is "lighter" than steel, but steel is stronger than aluminum, so one could imagine using thinner steel components to save weight without sacrificing (tensile) strength.
1095, a popular high-carbon steel for knives; it is harder but more brittle than lower-carbon steels such as 1055, 1060, 1070, and 1080. It has a carbon content of 0.90-1.03% [7] Many older pocket knives and kitchen knives were made of 1095. With a good heat treat, the high carbon 1095 and O-1 tool steels can make excellent knives.
Iron alloys are most broadly divided by their carbon content: cast iron has 2–4% carbon impurities; wrought iron oxidizes away most of its carbon, to less than 0.1%. The much more valuable steel has a delicately intermediate carbon fraction, and its material properties range according to the carbon percentage: high carbon steel is stronger but more brittle than low carbon steel.
