HFS-03 – SAF-HOLLAND Lock Standard Page 7 of 35Rev. K (6/11)3.0 Forge Source Requirements:3.1 Heating of the Material for Forging:3.1.1 Controls shall be in place to maintain the calibration of the furnace controls orindication equipment with a regular maintenance re-calibration procedure.3.1.2 Controls must be in place to ensure that each piece of material is uniformlyheated throughout the part. Care shall be taken to ensure material is notover-heated. Overheated material shall be scrapped.3.2 Traceability and Lot Control:3.2.1 The forge shop is responsible for maintaining material traceability and lotcontrol throughout the forging process on the basis of mill heat code andSAF-HOLLAND part number.3.2.2 Only locks of one mill heat and one SAF-HOLLAND part number shall bepacked in a shipping box. Parts of different mill heats shall not be mixed inany one box.3.2.3 Each box will be tagged to clearly indicate the part number, quantity, P.O.number and heat code on the outside of the shipping container. The packingslip will indicate the same information for each shipping box.3.3 Forging Process Control:3.3.1 The forge shop shall magnetic particle inspect a minimum of two (2) partsper hour, or any fraction of an hour, during the production run. For example,a production run of 2.5 hours would require 2 pieces minimum for the firsthour, 2 pieces minimum for the second hour, and 2 pieces minimum for theremaining 0.5 hour. Delays between production and Magnetic Particleinspection (MPI) are acceptable and are necessary for proper cooling andcleaning of parts. Samples for MPI must be identified to permit identificationof a lot or batch when a detected problem occurs and controls must be inplace to ensure that unacceptable material is not being shipped to a SAF-HOLLAND plant.3.3.1.1 Forged surfaces (un-machined). No circumferential indications arepermitted. Indication(s) may be ground in accordance with 3.3.1.2.3.3.1.1.1 Longitudinal indications are acceptable to a maximumlength of 0.25”.3.3.1.1.2 For linear indications the indications must be separatedby a distance greater than the length of an acceptableindication.3.3.1.1.3 Longitudinal indications are defined as any indicationparallel to the grain flow of the steel. Indications with acurved tail greater than .125” are no longer longitudinal
