Mold and Die Steels

STEELS FOR STRUCTURAL SECTIONS DME No. 1 Steel No. 1 Steel is a medium carbon (SAE 1030), silicon-killed forging quality steel with approximately 25% greater tensile strength than typical low-carbon warehouse steels. It machines easily, but is not “sticky,” permitting a faster and smoother cut. DME No. 2 Steel No. 2 Steel is an AISI 4130 type steel. 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 and dies.


No. 3 Steel is a P-20 AISI 4130 (modified) type cavity steel. Exceptionally clean, it is pre-heat treated to 28-34 HRC (271-321 Bhn). It provides high hardness, good machinability and exceptional polishability for both plastics molds and die cast dies. DME No. 5 Steel No. 5 Steel is a thermal shock resistant, hotwork die steel (AISI-SAE H-13 type). Supplied fully annealed 13-20 HRC (approx. 200 Bhn) 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 plastics molds with exceptional hardness or polishability require- ments. DME No. 5 Steel meets or exceeds the acceptance criteria established by the NADCA as detailed in Technical Digest Number 01-80-01D.
