HARDENING RFQ CHECKLIST ROCKVANTA Machinery | sales@rockvanta.com Related guide: https://rockvanta.com/resources/induction-vs-through-hardening/ Use this checklist with the current drawing. Mark unknowns for review. It is a request for quotation, not a released heat-treatment instruction. PART AND MATERIAL Part number / drawing revision: Quantity / repeat-order reference: Steel grade and applicable material specification: Delivery condition / previous heat treatment: Available material and treatment records: Blank dimensions / critical changes in section: REQUIRED RESULT Working surfaces and known load or wear conditions: Treatment route if mandated by the drawing: Hardened zones and transition limits: Areas to remain untreated / features requiring review: Surface hardness range, scale and method: Surface test locations and stage: Hardening depth range, definition and hardness criterion: Depth test method / applicable standard and edition: Depth measured from heat-treated or final finished surface: Core hardness, strength or toughness requirements, where applicable: Core test location and method, where applicable: FINISHING AND ACCEPTANCE Condition to be supplied after tempering / finishing: Grinding or machining allowance: Final dimensions, datums, straightness and runout: Restrictions on straightening or subsequent processing: Crack inspection method, stage and acceptance criteria, if required: Grinding damage checks, if required: Depth / cross-section sampling frequency: Sacrificial parts and associated cost: Coupon use, representativeness and approval, if proposed: Required records and batch / heat traceability: Person authorized to approve technical changes: Required delivery timing: OPEN QUESTIONS List missing requirements and any proposed deviations here: Before order release, agree the process and supplied condition, inspection scope, acceptance criteria, quantities consumed by testing and quotation exclusions. Surface hardness alone does not establish hardening depth, core toughness, crack freedom or final dimensional acceptance.
