X46Cr13

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. It has the highest carbon content of the SAE 420 series.[1][2][3]

Pros and cons

Pros

Advantages of X46Cr13 include its good workability when hot, potential to reach high hardness, up to 56 HRC,[4] and its moderately high carbon ratio of approximately .46%, which gives it a good compromise between high hardness and corrosion resistance for many applications.[5][6][7] It is also relatively inexpensive to produce.

Cons

X46Cr13 is a basic steel without molybdenum, nitrogen or vanadium. It can be outperformed (typically at higher cost) by more advanced steels like N680 with similar carbon content.[8][9]

Uses

Common uses include:

- knife blades,[10][11][12] [13][14][15]

- surgical instruments,[16][17][18][19]

- bearings,[20] [21]

- valves and pumps,[21]

measuring devices

spring wire.[22]

It is also used in the manufacture of heat treated steel pipes used for CO2 carbon capture and storage.[23][24][25][26]

A commercial variant of X46Cr13 with some Vanadium is known as 420HC and is used in the knife industry because of its ability to hold a superior edge.[27][28]
