Cr-Mo-W alloy steel P92
Purchase and sale of P92 scrap and turnings (tungsten 9Cr-2W steel for power plants) in regular quantities for European consumers. Fast quotations and collection across the whole territory.
Tungsten 9Cr-2W martensitic alloy steel with boron and nitrogen micro-additions, an evolution of P91 with greater creep resistance. Markets: supercritical thermal power plants, ultra-high-pressure boilers, steam piping.
- Forms scrap · tube cut-offs · turnings · offcuts
- Density ~7.78 g/cm³ (indicative)
- Rm ≥ 620 MPa
Main elements
| Chromium (Cr) | 8.5 – 9.5 % |
|---|---|
| Tungsten (W) | 1.5 – 2.0 % |
| Molybdenum (Mo) | 0.30 – 0.60 % |
| Vanadium (V) | 0.18 – 0.25 % |
| Niobium (Nb) | 0.06 – 0.10 % |
| Carbon (C) | 0.07 – 0.13 % |
| Nitrogen (N) | 0.030 – 0.070 % |
| Iron (Fe) | balance |
Indicative values according to ASTM A335 / EN 10216-2 (Grade 92). It also contains controlled boron micro-additions (B ~0.001 – 0.006 %), decisive for creep resistance. Steel for high-temperature applications, NOT a high-speed steel; composition certified for each batch.
Physical and mechanical data
| Density | ~7.78 g/cm³ (indicative) |
|---|---|
| Tensile strength Rm | 620 – 850 MPa |
| Yield strength Rp0.2 | ≥ 440 MPa |
