Tool Steel H26

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

Anneal at 1625 F and slow cool at 40 F maximum per hour.

Applications

Applications are those that involve hot forming temperatures such as hot extrusion or forming dies.

Cold Workability

H26 may be cold formed by conventional methods.

Forgeability

Forge at 2100 F down to 1775 F. Do not forge below 1750 F.

Formability

The alloy may be formed by conventional methods.

Hardening Procedure

See "Heat Treatment" and "Tempering".

Heat Treatability

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.

Hot Workability

See "Forging".

Machinability

Machinability of H26 is medium. It rates at 60% that of the W group (rated 100%) water hardening low alloy tool steels.

Principle 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.

Tempering Procedure

Temper at 1050 F to 1250 F for Rockwell C of 58 to 43. A double (repeat) temper is advised for best results.

Weldability

This alloy is weldable. Consult the supplier for details.
