1.4313 - F6NM - UNS S41500 is a corrosion and acid resistant, soft martensitic chromium-nickel steel with added molybdenum.
The high toughness properties provide 1.4313 with excellent capabilities and increasing popularity. Valves, compressors, and centrifuges are typically made of this stainless steel.
Steel 1.4313 - also known as F6NM - is primarily used in the oil industry and in components for power plants and reactor technology.
This stainless-steel grade is also used for the manufacture of turbines for hydroelectric power plants.
The material 1.4313 is available in QT650, QT780 and QT900:
| QT650 | QT780 | QT900 | |
| Tensile strength | 650 - 830 N/mm2 (Rm) | 780 - 980 N/mm2 (Rm) | 900 - 1100 N/mm2 (Rm) |
| Hardness according to Brinell | 192 - 242 HB | 245 - 309 HB | 285 - 346 HB |
Mechanical properties at room temperature: QT650
| Re | A | Z | KV |
| N/mm2 | % | % | J |
| ≥ 520 | ≥ 12 | ≥ 40 | ≥ 54 |
Mechanical properties at room temperature: QT780
| Re | A | Z | KV |
| N/mm2 | % | % | J |
| ≥ 635 | ≥ 15 | ≥ 40 | ≥ 50 |
Mechanical properties at room temperature: QT900

The stainless steel 1.4313 features excellent mechanical properties. The addition of molybdenum provides medium corrosion resistance, which can be improved by polishing the surfaces.
Weldability: poor
Machinability: 5 (1 = poor - 10 = good)
Polishability: yes
Corrosion class: 2 (0 = poor - 5 = good)
In the tempered condition, 1.4313 has a tensile strength of 650 - 1100 N/mm². The toughness properties exist from -60°C to +300°C. 1.4313 can be magnetised.

The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.
Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
