Quantity
As a senior fastening engineer, I confirm that this DIN Nut, manufactured from Hastelloy C-22 (W.Nr.2.4602), represents a premium solution for extreme service conditions. Sourced directly from a Chinese factory direct supply channel, it offers both technical excellence and cost efficiency for global industrial buyers.
Material & Design
The alloy contains ~56% nickel for matrix stability, ~22% chromium for a self-healing Cr₂O₃ oxide layer, ~13% molybdenum to resist pitting and crevice corrosion, ~3% tungsten for high-temperature creep strength, and ~3% iron for processability. This balanced composition ensures outstanding performance in both oxidizing and reducing media.

High-Temperature Mechanical Performance
At 600°C, this DIN Nut maintains tensile strength of 450–550 N/mm² (far surpassing 316L stainless steel), yield strength of 250–350 N/mm², and elongation above 30%, preserving ductility and fracture resistance. Creep rate stays below 1×10⁻⁸/s under 100 MPa stress, and fatigue life under thermal cycling greatly exceeds that of ordinary alloys—critical for burner flanges, turbine casings, and reactor nozzles.

Corrosion Resistance in Aggressive Media
Oxidation rate at 600°C is only 0.02 mm/year, versus ~0.1 mm/year for 304 steel. In high-temperature sulfuric acid (e.g., FGD scrubbers), corrosion is below 0.1 mm/year; in chloride-laden incinerator flue gas, pitting and crevice corrosion remain under 0.05 mm/year. The nut also resists sulfide, chloride, and alkaline fly-ash erosion, making it indispensable for waste-to-energy plants and petrochemical heaters.
