Introduction to K418 Master Alloy Bar
K418 is a γ′-phase strengthened nickel-chromium-based superalloy developed for demanding hot-end applications. Supplied as high-purity master alloy bars (casting rods), it is vacuum-melted and carefully controlled to ensure consistent chemistry and excellent castability.
The alloy is typically used in the as-cast condition and offers a reliable balance of high-temperature strength, thermal fatigue resistance and environmental tolerance. Its cobalt-free formulation reduces cost while maintaining superior performance compared with many cobalt-containing counterparts. Density is approximately 8.0 g/cm³ and the melting range is 1295–1345°C, making it highly suitable for precision investment casting of complex turbine components.
Product Features of K418/713C Master Alloy Bar
√Optimized High-Speed Stability: Engineered to maintain 900MPa+ tensile strength under intense centrifugal stress at 100,000+ RPM.
√Ultra-Clean VIM Extraction: Advanced vacuum induction melting keeps oxygen content below 15ppm for defect-free rotor castings.
√Superior Thermal Fatigue Life: Formulated to withstand the rapid heating and cooling cycles of high-efficiency turbocharged engines.
√Excellent Oxidation Resistance: High Chromium (12-13.5%) and Aluminum (5.5-6.5%) content forms a stable passive layer against hot gas erosion up to 900°C.
√Precise Solidification Window: Controlled chemical matrix ensures predictable shrinkage rates, crucial for aerodynamic profile accuracy in investment casting.
