Product Description
Anti-hydrogen Sulfide Corrosion Hardened 92HRA Tungsten Steel Piston Shaft
Traditional alloy piston shafts | Disruptive value of this product |
65HRC hardness → micro deformation accumulation under high pressure | 92HRA hardness tungsten carbide → 97% reduction in deformation |
Thread stress concentration → fracture risk ↑ | Rolling reinforced thread → 300% increase in fatigue life |
Hydrogen sulfide corrosion → seal failure | Nano sealing surface → Leakage rate <0.001mL/min |
Material composition:
▸ Material composition: 94% WC + 6% Co nanopowder (D50=0.5μm)
▸ Sintering process: low-pressure SPS sintering (1200℃/50MPa)
▸ Grain size: 0.8-1.2μm (breaking the 3μm limit of traditional sintering)
▸ Matrix hardness: 92.5HRA
Applications:
► Energy exploration
- Shale gas fracturing compressor: Resistant to 10,000ppm H₂S intergranular corrosion
- Supercritical CO₂ compression: Resistant to 31MPa/110℃ phase change shock
► Chemical extreme environment
- Hydrofluoric acid reactor compressor: Resistant to HF vapor corrosion (>200℃)
- Liquid chlorine delivery system: No brittle fracture at -34℃ low temperature
► Aerospace field
- Aerospace fuel booster pump: Stable operation at -196℃ in liquid oxygen environment
- Nuclear-grade helium circulation compressor: Resistant to neutron irradiation embrittlement
