ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5712 Rene 41 solution bar at factory-direct prices with full material traceability and fast global delivery. Rene 41 is a precipitation-hardenable nickel-base superalloy strengthened by the formation of gamma-prime [Ni₃(Al,Ti)] during aging. The alloy is produced using vacuum melting (VIM + VAR/ESR) to ensure high purity and metallurgical consistency. The AMS 5712 condition is solution heat treated and precipitation hardenable — supplied in the soft, workable state for forming and machining, with final properties achieved after aging. Available Forms: Bar (up to 3.00″ / 76.2 mm), forgings, flash welded rings (up to 3.00″ radial thickness), forging stock, heading stock; also sheet, strip, plate, wire, rod, flat bar, welding wire Specifications: AMS 5712 (solution treated), AMS 5713 (VAR), AMS 5545 (sheet/strip/plate), AMS 5800 (welding wire), UNS N07041, Werkstoff Nr. 2.4973
Fabrication & Material ComparisonSolution Treatment (As-Supplied): 1066-1177°C (1950-2150°F), water quench or rapid air cool Aging: 760°C (1400°F) × 16 hours, air cool Cold Working: Can be cold worked to adjust mechanical properties Machining: Good machinability in solution treated condition; more difficult after aging Heading: Heading stock available for fastener manufacturing Flash Welded Rings: Available for seamless, high-integrity ring components
