CarTech™ Ferrium® C64®
Product catalog summary
Typical Composition: The composition of CarTech Ferrium C64 includes Carbon (0.11%), Chromium (3.5%), Nickel (7.5%), Cobalt (16.3%), Molybdenum (1.75%), Tungsten (0.2%), and Vanadium (0.02%).
Product Overview: CarTech Ferrium C64 is a high-quality carburizing steel known for its high core strength, fatigue strength, temperature resistance, and hardenability. It undergoes a double-vacuum VIM/VAR process for optimal metallurgical quality. It achieves a carburized case hardness of 62-64 HRC, surpassing conventional gear steels like 8620 and 9310, and offers high core properties for demanding applications.
Applications: This steel is ideal for power transmission shafts, gears, and other demanding applications in aerospace, energy, and racing industries, where weight savings, compactness, and high surface fatigue resistance are crucial.
Mechanical Properties: At room temperature, the yield strength is 199 ksi (1372 MPa), ultimate tensile strength is 229 ksi (1579 MPa), elongation is 18%, reduction of area is 75%, and fracture toughness is 85 ksi√in (94 MPa√m).
Benefits: Key benefits include high surface hardness, fatigue strength, temperature resistance, and corrosion resistance.
Product Forms: Available in billets and bars.
Specifications: Conforms to AMS 6509 and is protected under US Patent Number 8,801,872.
Physical Properties: Density is 0.288 lb/in³ (7.98 g/cm³). The mean coefficient of thermal expansion varies with temperature, ranging from 5.29 x 10-6 in/in/°F (9.53 x 10-6 mm/mm/°C) at 75-200°F to 5.69 x 10-6 in/in/°F (10.25 x 10-6 mm/mm/°C) at 75-1000°F.
Cleanliness Requirements: Conforms to AMS 2300 magnetic particle cleanliness and typically satisfies ASTM E-45 microcleanliness ratings.
Hardenability: The average Jominy end quench hardenability shows consistent Rockwell C hardness values, with a slight decrease from 43 to 42.5 as distance from the quenched end increases.
Fatigue Property Data: Preliminary data on single tooth bending fatigue properties is available.
