Sandvik 14C28N® is a martensitic stainless chromium steel with a chemistry optimized for high quality professional knife applications. The chemical composition provides a unique combination of properties including:
- Excellent edge performance
- Very high hardness
- Good corrosion resistance
Sandvik 14C28N® is mainly recommended for knife applications which put very high demands on edge sharpness, edge stability and corrosion resistance. Examples are pocket knives, chefs knives, hunting knives and fishing knives.

Forms of supply
The strip steel can be supplied either in coils or as straightened lengths of 0.5–4.0 m (1.6–13.1 ft). The coil weight is max. 5 kg/mm (2800 lb/in) of strip width.
Hardening and tempering of the strip steel is needed to achieve the correct finish and to meet the properties required by the end user.

|1.0 (0.039)||4.5 (0.177)||5 (0.1968)||380 (14.96)|
Other sizes can be offered on request.
The physical properties of a steel are related to a number of factors, including alloying elements, heat treatment and manufacturing route, but the data presented below can generally be used for rough calculations.
Density : 7.7 g/cm3 (0.28 lb/in3)
|Soft annealed||max. 700 (102)||max. 215||max. 94.3|
|Annealed||750 ±100 (109±14)||235 ± 35||97.4 ± 6|
|Cold rolled||700-1100 (102-160)||215-345||94.3-108.7|
