H13 HOT WORK TOOL STEEL

 

 

APPLICATIONS

H13 is particularly suitable for aluminium , zinc and magnesium die casting tools where resistance to heat checking is of prime importance.
Other uses include extrusion dies and mandrels, hot piercing tools, hot blanking and forging dies, shear blades, hot punches and die inserts.

 

ANNEALING

If possible pack in a suitable sealed container with spent carburising mixture or cast iron chippings.  Heat to 850C / 870C, hold for sufficient time to ensure uniformity, then cool no faster than 25C per hour to 650C followed by air cooling.  This should result in a hardness of 235 HB maximum.
