Steels for Structural and Holder Block Applications
D-M-E #1 Steel is a medium carbon quality steel with
greater tensile strength than typical plain carbon warehouse steels. It machines easily, but is not “sticky”, permitting a faster and smoother cut. International comparisons: DIN 1.1178 (CK 30) and 1.1730 (C 45 W); JIS S 30 CM, S50C, S55C; ISO 683-1 C30E4.
D-M-E #2 Steel is a medium alloy steel specified for
durability in structural applications. It is supplied pre-heat treated to 28-34 HRC (271-321 Bhn). A high strength steel, it is ideal for cavity and core retainer plates, clamping plates and support plates in molds. International comparisons: DIN 1.2312 (40CrMnMoS 8 6), 1.7218 (25CrMo4) and 1.2331 (41CrMoS4); JIS SCM 430; ISO 683-2 Type 1.
D-M-E #7 Steel  is a modified AISI 400 series stainless
steel for holder block applications. It is supplied pre-heat
treated to 32-36 HRC (302-340 Bhn). This stainless steel offers corrosion-resistance and exceptional m
achinability but cannot be further hardened (see D-M-E #6). For humid environments, corrosive plastics, “clean room” or “100% stainless” applications, it is an ideal choice for all structural mold plates. International comparisons: none.
Steels for Cavity & Core Applications
D-M-E #3 Steel  is a P-20 AISI 4130 type cavity steel.
Exceptionally clean, it is pre-heat treated to 28-34 HRC (271-321 Bhn). It provides good machinability, the ability to heat treat to higher hardness, and exceptional polishability.  International comparisons: DIN 1.2311 G40CrMnMo7; JIS none; ISO none.
D-M-E #5 Steel  is an AISI/SAE H-13 type thermal
shock resistant, hotwork die steel.  Supplied fully annealed (approximately 200 Bhn; 13-20 HRC) for easy machinability, it can be subsequently heat treated to the desired hardness with a minimum of deformation.  Mainly used for die cast dies, it is also suitable for plastic molds with exceptional hardness or polishability requirements. D-M-E #5 Steel meets or exceeds the acceptance criteria established by the NADCA as detailed in Technical Digest Number 01-80-01D. International compari-sons: DIN 1.2344 (X40CrMoV5-1); JIS SKD 61; ISO 4955 H13.
D-M-E #6 Steel  is a modified AISI 420 type stainless steel.
It is supplied fully annealed to 179-241 Bhn (8-23 HRC), making it readily machinable. Unlike D-M-E #7 steel, D-M-E #6 steel is a cavity-grade material that can be subsequently heat
treated to the desired hardness and has excellent polishability. International comparisons: DIN 1.4028  (X30Cr13); JIS SUS 420 J 2; ISO none.

D-M-E regularly mixes steel types within a mold base assembly to deliver plates configured to your application requirements. You can select steel types for each plate, as available from the table at left, in any combination
for your mold base.
The American Standard Mold Base is available in 43 nominal
sizes to match the mold space requirements for your application.
As the creator of the American mold base standard, D-M-E has
the largest selection of mold base sizes and most are available in
less than five business days.
NOTE:Drilled complete replacement plates available
with quick delivery.
NOTE:Approximate mold base weight can be estimated with the following formula:
WEIGHT = WIDTH x LENGTH x HEIGHT x .283 x 90%
= Ships in 5 days or less
