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

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

Die Materials Specification Task Group
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
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?
Die Materials Specification Task Group
Moving Forward:
• December 2005: Finalize hardened CVN spec limits
• January 2006: Approve draft of NADCA #207-2006
• February 2006: Release NADCA #207-2006
