with moldmaking around the world are the D-M-E Steel TypesOur experience in mold steel ensures the cleanliness, durability and machinability appropriate to your application D-M-E #1 Steel D-M-E #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. Typical analysis is C 0.30%, Mn 0.75%, P 0.04%, S 0.05%, Si 0.25%. D-M-E #2 Steel D-M-E #2 Steel is an AISI 4130 type steel. It is supplied pre-heat treated to 28-34 Rc (269-321 Bhn). A high strength steel, it is ideal for cavity and core retainer plates, clamping plates and support plates in molds. Typical analysis is C 0.30%, Mn 1.20%, P 0.03%, S 0.04%, Si 0.28%, Cr 0.75%. D-M-E #3 Steel D-M-E #3 Steel is a P-20 AISI 4130 (modified) type cavity steel. Exceptionally clean, it is pre-heat treated to 29-36 Rc (277-331 Bhn). It provides high hardness, good machinability and exceptional polishability. Typical analysis is C 0.30%, Mn 0.85%, P 0.015%, S 0.003%, Si 0.30%, Cr 1.10%, V 0.08%, Mo 0.55%. D-M-E #7 Steel D-M-E #7 Steel is a modified AISI 400 or equivalent series stainless steel for holder block applications. It is supplied pre-heat treated to 32-36 Rc. This special grade of 420F offers exceptional machinability but cannot be further hardened. For humid environments, corrosive plastics, "clean room" or "100% stainless" applications, it is an ideal choice for all structural (non-cavity/core) mold plates. Typical analysis is C 0.05%, Mn 1.30%, S 0.13%, Si 0.50%, Cr 12.00%, Cu 0.50%. |   |
