Conducted by the Die Materials Specification Subcommittee November 1 st & 2 nd 2005

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

2. Die Materials Specification Task Group 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

3. Die Materials Specification Task Group • 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

14. Carpenter Pyrotough 78 0.005 max 0.40 1.45 1.00 4.45 2.10 0.80 Lo Cr, Hi Mo Die Materials Specification Task Group • Moving Forward – September 2005: • Review Groupings by Chemical Composition • Review Hardening Temperatures within each Grade • Review Capability Toughness within each Grade • Consider Listing Only “Remelted” Grades • Except ‘Premium H13 “Grade A” • Consider Deleting “Shepherd Fracture” Grain Size • Review Toughness Requirement After Heat Treating - • Currently CVN required for “Superior” Grade H13 • New Spec: CVN - Optional or Mandatory ? • Evaluate “Acceptance” Values

15. 0.005 max 0.40 1.45 1.00 4.45 2.10 0.80 Lo Cr, Hi Mo Carpenter Pyrotough 78 Die Materials Specification Task Group • Moving Forward – November 2005: • Finalized Groupings by Chemical Composition • Reviewed Hardening Temperatures within each Grade • Reviewed Capability Toughness within each Grade • Single Inclusion limit for all grades; A - H • Deleted “Shepherd Fracture” Grain Size • Review Toughness Requirement After Heat Treating - • Class 1: Mandatory CVN testing for heat treat quality • Class 2: CVN testing for heat treat quality not required • Evaluate “Acceptance” Values; 80% rule?
