Tantung Cutting Tools
Still cuts at 1500°
Tantung blades will not anneal at 1500°F
Maintains cutting edge hardness throughout tool life.
Longer tool life than HSS.
Broad operating speeds
Tantung works at speeds of up to 450 SFPM.
Operates at speeds where HSS fails.
Effective at speeds where cemented carbides load-up
Won't chip like carbides at lower speeds.
New life for older machines
Tantung can be used on machines where speeds and rigidity are limited.
With tantung tools, older machines can handle increased production loads and help reduce costs.
Performs interrupted cuts significantly better than carbides.
Tantung's Inherent Superiority
Tantung's chemical composition and manufacturing process amount for its wear resistance, toughness and red heat hardness.
Corrosion resistant non-magnetic alloys.
Melted in electric furnaces and cast in chill molds imparts:
Rapid solidification for very fine grain structure
400 x 10³ psi
Youngs' Modulus: 41 x 10
Tantungs* low co-efficient of friction makes it an ideal cutting/slicing material.
Density (72°F) 8.3³g/cm
Melting range: 2100-2200F
Co-efficient of linear thermal expansion:
(100-1200°F) 4.2 x 10
Rockwell C hardness
Brinell hardness: 479 at 1200°F
Transverse Rupture Strength
300 x 10³ psi (almost twice that of other cast alloys)
