AMS 5405 (B-1900) INVESTMENT CAST ROUND BAR INTRODUCTION TO AMS 5405 SUPERALLOY AMS 5405 REPRESENTS A CRITICAL AEROSPACE-GRADE NICKEL-BASED SUPERALLOY SPECIFICATION, OFFICIALLY DESIGNATED AS ALLOY CASTINGS, INVESTMENT, CORROSION AND HEAT RESISTANT, 64NI - 8.0CR - 10CO - 6.0MO - 1.0TI - 4.2TA - 6.0AL - 0.015B - 0.08ZR, VACUUM MELTED, VACUUM CAST, AS CAST. THIS SPECIFICATION, DEVELOPED BY SAE INTERNATIONAL, GOVERNS THE PRODUCTION OF INVESTMENT CAST COMPONENTS FROM A HIGH-PERFORMANCE NICKEL SUPERALLOY COMMONLY KNOWN IN THE INDUSTRY AS B-1900. THE MATERIAL IS ENGINEERED FOR EXTREME ENVIRONMENTS WHERE OXIDATION RESISTANCE, CORROSION RESISTANCE, AND HIGH-TEMPERATURE STRENGTH ARE PARAMOUNT. THE ALLOY SYSTEM RELIES ON A PRECIPITATION-HARDENED NICKEL MATRIX REINFORCED BY TANTALUM, ALUMINUM, AND TITANIUM ADDITIONS, DELIVERING EXCEPTIONAL PERFORMANCE AT TEMPERATURES APPROACHING 980°C (1800°F). CHEMICAL COMPOSITION AND METALLURGICAL PROPERTIES BASE CHEMISTRY (NOMINAL COMPOSITION) THE AMS 5405 SPECIFICATION DEFINES A PRECISE CHEMICAL COMPOSITION BY WEIGHT PERCENTAGE: NICKEL (NI): BALANCE (APPROX. 64%) CHROMIUM (CR): 8.0 COBALT (CO): 10.0 MOLYBDENUM (MO): 6.0 TITANIUM (TI): 1.0 TANTALUM (TA): 4.2 ALUMINUM (AL): 6.0 BORON (B): 0.015 ZIRCONIUM (ZR): 0.08 THIS SPECIFIC CHEMISTRY CREATES A UNIQUE MICROSTRUCTURE THAT PROMOTES THE FORMATION OF THE Γ' (GAMMA-PRIME) PHASE NI₃(AL, TI, TA), WHICH PROVIDES SUPERIOR HIGH-TEMPERATURE CREEP RESISTANCE AND THERMAL STABILITY .
