|
Applications
|
|
T6 is used for cutting tools and drills.
|
|
|
Machinability
|
|
The machinability of this alloy is relatively low, rating about 45% that of the W group water hardening simple alloy tool steels.
|
|
|
Forming
|
|
T6 may be formed in the annealed condition by conventional methods.
|
|
|
Welding
|
|
This alloy may be welded. However it has a high tungsten and high cobalt content such that the alloy supplier should be consulted for welding practice.
