Martensitics
Martensitic stainless steels have high resistance to atmospheric oxidation environments, without substantially decreasing hardness (up to 500°C). This means that they can be used in operations that require resistance to high-temperatures.
Because of this characteristic, they are used in the food, beverage, chemical, petrochemical, machinery and equipment industries. It can be used in cutlery items, shafts, surgical instruments, screws, nuts, blades and other parts for steam turbines, as well as valves and valve rods.
Villares Metals supplies the following martensitic stainless steels:
VC140 (AISI 410)
Steel featuring high mechanical strength and moderate corrosion resistance. Used in steam valves and rods, nuts, as well as in screws and studs used by the oil industry.
- ABTN | ASTM | SAE | AISI: 410
- DIN | WNr: 1.4006
- Chemical Composition:
| C % | Mn % | Cr % | Si % |
| 0,13 | max. 1,00 | 12,00 | <=1,00 |
V416
Corrosion resistant martensitic steel, similar to VC140, with addition of sulfur for improved machinability.
