3.REQUIREMENTS:
3.1Shot:
3.1.1Material: The shot ud shall be made from cast iron, cast steel, cut steel wire (or stainless cut
wire), glass, or ceramic as specified or approved. The hardness shall be determined by any of the various methods applicable to small ctions at loads determined to provide a reliable conversion to Rockwell C. Steel and iron shot shall conform to MIL-S-851. For steel parts over 200,000 psi tensile strength, u hard steel shot in the range 55-65 HRC or ceramic shot, hardness
comparable to 57-63 HRC, unless otherwi specified (e 6.14). Stainless steel cut wire shot, type 302 or 304 (condition B spring temper), and carbon steel cut wire shot shall conform to
SAE J441. Glass beads shall conform to MIL-G-9954 except for sieve analysis. Ceramic beads shall meet the requirements of SAE J1830.
3.1.2Size: Unless otherwi specified, the size of shot charged into the machine, whether new shot,
ud shot, or reclassified shot, shall be at the option of the contractor and shall be as specified in table II (cast sizes), table III (cut wire sizes), table IV (glass bead sizes) or table V (ceramic bead sizes).
3.1.3Shape: The shot or beads shall be free from sharp edges and inspected for deformed shapes or
broken shapes when examined per 4.3.1, 4.3.3, and figure 7. Cut wire shot, if ud, shall be
preud or burnished to eliminate sharp edges (e 6.17.1). A given sample size shall contain no more than the number of unacceptable deformed shapes as shown in figure 7, and defined in
table I below (e 3.3.9).

3.2Equipment:
3.2.1Automatic shot peening: The machine ud for shot peening shall provide means for propelling
shot by air pressure or centrifugal force against the work, and mechanical means for moving the work through the shot stream or moving the shot stream through the work in either translation or rotation, or both, as required. The machine shall be capable of reproducing consistently the shot peening intensities required. Except for wet glass bead peening (e 3.3.9), the equipment shall continuously remove broken or defective shot so that this shot will not be ud for peening.
3.2.2Computer-controlled shot peening: When specified in the contract or purcha order (e 6.2 and
6.8), the machine ud for shot peening shall be as in 3.2.1 and also shall be equipped with
computer aided monitoring equipment. This equipment shall continuously monitor critical process parameters through interaction with a nsing system. The media shall be metered to each nozzle a
有心的成语nd wheel with the desired shot flow. Process parameters shall be as specified by the procuring activity (e 6.9). The machine shall be stopped immediately and corrective action shall be taken when any of the established process limits is violated. The electronic system ud for monitoring and controlling shot peening shall include a data recording device which will mark (plot) process interruptions or inconsistencies, and shall be maintained for the purpo of providing a hard copy record.
3.3Procedure:
3.3.1Dimensions and condition of parts: Areas of parts to be shot peened shall be within dimensional
and surface finish requirements before peening. All heat treatment, machining and grinding shall be completed before shot peening. All fillets shall be formed, all burrs shall be removed, and all sharp edges and corners to be peened shall be provided with sufficient radii to result in complete coverage without any distortion prior to peening (e 6.15).
3.3.2Precleaning: Except as otherwi specified or permitted, all areas to be peened shall be cleaned in
accordance with MIL-S-5002. Procedures for stripping coatings shall be as specified or approved in the contract or on the applicable drawings.

3.3.3Masking: Areas of the part or work piece and the dimensional tolerances of the areas which are
designated in the contract or applicable drawing to be free from any shot peening marks shall be suitably masked or otherwi handled to protect such surfaces from the shot stream or subquent damage. Areas not requiring peening and not required to be masked shall be considered optional.
3.3.4Magnetic particle or penetrant inspection: Except as otherwi specified, when magnetic particle
削切or dye penetrant inspection is required, parts shall be subjected to such inspection before peening.
素质目标3.3.5Loading: Unless otherwi specified or permitted, parts shall be free from externally applied loads

or forces during shot peening.
