• On “rework” orders, the original PO number shall be noted on supplied documents
• Certification information requirements

• Material
• Material Hardness
• Areas of welds, weld repair, inlays, cladding, dissimilar materials, etc.
• NOTE: If the above information is not provided on the Purchase Order, HP&C will process the parts without a strike,
  which may lead to adhesion failures. HP&C will not be responsible for reworks/failures if this information is not provided.
• Electroless nickel stripping: All parts shall be stripped per HPC WI 7.2 (latest revision). A copy shall be sent upon request.
• If a hydrogen embrittlement bake (pre or post) is required, it must be called out on the PO with the specific time cycle and temp.
• If parts are to be plated 100%, customer must indicate on the PO or drawing the possible locations on the parts that can be contacted for plating.
  Areas of contact will have plating voids or no plating at all.
