X65Cr13 is characterised by its high hardenability in conjunction with good corrosion resistance in moderately corrosive environments. Due to its higher carbon content, 1.4037 is more hardenable than 1.4034. It is used in the quenched and tempered condition and due to its high hardness, it is ideally suited for the production of cutting tools of all sorts and surgical implements.

1.4037 can be soft annealed by holding at a temperature in the range 750 to 850 °C followed by slow cooling in an oven or in air. In this condition, the following mechanical properties can be expected:
Property Specification
tensile strength (N/mm2) Rm ≤ 800
hardness HB ≤ 245
Although 1.4037 is generally not welded, it can be soldered in some instances.
