Recommended Procedures for H-13 Tool Steel
These acceptance
criteria and specifications are not intended for
all die casting applications. They apply where
high volume production or critical performance
is required. Die casters and tool builders
should insist that certification of the Material
Quality accompany each piece of Special Quality
die steel purchased for use in die casting dies
and that certification of the Heat Treatment
Quality accompany each furnace load of Special
Quality die steel hardened in accordance with
this protocol.
For applications
requiring a high level of Material Quality and
Heat Treatment Quality, a variety of
commercially available Special Quality die
steels are listed in this specification,
designated as Grades B – E, Class 1 or 2, and
should meet the appropriate specification
requirements of NADCA #207-2006.
For applications
requiring a lesser level of Material Quality
and/or Heat Treatment Quality, Premium H13 die
steel is available and should meet the
specification requirements of NADCA #207-2006 as
Grade A, Class 1 or 2.
