F6NM material

F6NM martensitic chromium-nickel steel is rust and acid resistant with molybdenum addition. It has medium corrosion resistance. The ever-increasing demand for F6NM is due to its good toughness properties and the resulting versatile performance range. The soft-martensitic and stainless steel is used for valves, compressors or centrifuges.

F6NM ss material is used in the petroleum industry, in the manufacture of turbine runners for hydroelectric power plants, and for components in power plant and reactor construction.

Characteristics

F6NM stainless steel has very good mechanical properties. The addition of molybdenum gives medium corrosion resistance. However, this can be improved by polishing the surfaces. The stainless material is suitable for forging, but less so for welding.

Important questions

What is the tensile strength of F6NM?
The tensile strength can vary from 650 MPa to over 1100 MPa depending on the property state.

At what temperature can F NM be hardened?
F6NM is annealed within the temperature range of 950°C to 1050°C and then hardened by rapid cooling using air, oil, polymer, or water.

Is F6NM magnetic?
F6NM is a ferromagnetic material.

How can F6NM be hardened and tempered?
The process involves first hardening F6NM to a martensitic structure and then tempering at temperatures above 500°C.

Is F6NM corrosion resistance?
While F6NM is corrosion-resistant, it can still rust under certain environmental conditions.

What ist he density of F6NM?
The density of 1.4313 ranges from 7.70 to 7.85 kg/cm³, depending on its precise composition.

What ist he Machinability of F6NM?
The machinability varies with the hardness level, but it can generally be considered good compared to other high-alloy steels.
