Principal Design Features
|
|
This alloy is one of the Hot Work, higher tungsten content with chromium and vanadium tool steels. It has good resistance to softening when used in hot applications.
|
|
|
Applications
|
|
Applications are those that involve hot forming temperatures such as hot extrusion or forming dies.
|
|
|
Machinability
|
|
Machinability of H26 is medium. It rates at 60% that of the W group (rated 100%) water hardening low alloy tool steels.
|
|
|
Forming
|
|
The alloy may be formed by conventional methods.
|
|
|
Welding
|
|
This alloy is weldable. Consult the supplier for details.
|
|
|
Heat Treatment
|
|
Preheat to 1600 F and then raise temperature rapidly to 2225 F. Hold for 2 to 5 minutes at temperature and then air cool, oil, or salt bath quench.
|
|
|
Forging
|
|
Forge at 2100 F down to 1775 F. Do not forge below 1750 F.
|

|
|
Cold Working
|
|
H26 may be cold formed by conventional methods.
|
|
|
Annealing
|
|
Anneal at 1625 F and slow cool at 40 F maximum per hour.
|
|
|
Aging
|
|
Not applicable to this alloy.
|
|
|
Tempering
|
|
Temper at 1050 F to 1250 F for Rockwell C of 58 to 43. A double (repeat) temper is advised for best results.
