1. Conducted by the Die Materials Specification Subcommittee November 1 st & 2 nd 2005 Die Materials Specification Task Group Die Steel Quality & Heat Treatment Acceptance Criteria

2. OBJECTIVE: Adding other die materials to the NADCA spec:  Revise Current #207 Specification :  Similar Acceptance Criteria for “All” Materials  Single Spec Criteria for “All” Die Materials  Limit Materials to H13/H11 & “modified” Compositions  Group similar compositions together  Range of compositions must not alter microstructures Die Materials Specification Task Group

3. Ford AMTD-DC2010 Rev K  16 grades

4. Die Materials Specification Task Group “Nominated” Grades & Supply Technical Data  18 grades  6 “categories ”  H13 (7)  H11 (1)  H11-low Si (3)  H11-hi Mo (3)  DIN 1.2367 (3)  DIN 1.2367 mod (1)

5. Die Materials Specification Task Group Group Materials by Similar Compositions:  “Grade A” = Premium H13  “Grade B” = Superior H13  “Grade C” = Modified H13  “Grade D” = DIN 2367  “Grade E” = Modified 2367  “Grade F” = H11  “Grade G” = Modified H11 – low Si  “Grade H” = Modified H11 – high Mo
