Alloy ТН20
Designation
Description
Alloy ТН20 used: for the manufacture of a cutting tool (for finishing and semi-finishing turning operations with continuous cutting carbon low-alloy structural steel, non-ferrous metals based on copper, low-alloyed Nickel alloys, gray iron and polyethylene, finish and semi-finish face milling of cast iron workpieces); the manufacture of wear-resistant parts (blast nozzles of nozzles, fume matrices, mud pumps valves, rings and bushings plungers, parts, measuring equipment parts for bonding, rollers-plates, of measuring tools (end measures of length, gauges, brackets, etc.) personalki in the manufacture of rubber products).
Note
The sintered hard alloy based on titanium carbide.
Standards
Chemical composition
The basis is titanium carbide.
In accordance with GOST 26530-85 the composition is given for a hard alloy of grade TN20. The content of titanium carbide in the alloy should be 79.00%. The content of the main components in the mixture of the initial powders is given without taking into account impurities. The contents of the main components are indicated for the preparation of a powder mixture. To produce the alloy, titanium carbide TiC 0.85 -TiC 094 is used . In the alloy, the content of tungsten in the carbide component is allowed up to 4.50%.
