X46Cr13 is the European Norm name for a common martensitic stainless steel with the numeric name 1.4034. It is equivalent to American Iron and Steel Institute standard 420C (also known as 420HC). It has the highest carbon content of the SAE 420 series.Stainless steels, table of technical properties Euro InoxStainless Steel Grades Datasheets BRITISH STAINLESS STEEL ASSOCIATION
Properties X46Cr13 has good workability when hot, and potential to reach high hardness of up to 56 HRC. 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.Comparison between X5CrNiCuNb16 and X46Cr13 under Corrosion Fatigue Marcus WolfProperties that Characterize the Material X46Cr13 Steel 8nd International Conference on Physical and Numerical Simulation of Materials Processing It is also relatively inexpensive to produce.
X46Cr13 is a basic steel without molybdenum, nitrogen or vanadium. It can be outperformed (typically at a higher cost) by more advanced steels like N680 with similar carbon content.X46Cr13 datasheet Make it fromHow good is N680 steel Knife Up
