Following is delivery CONDITION of 32CrMoV12-10 forged bars: Air melt/Ladle refined, VIM-VAR, or ESR hot forged, normalized, austenitized,quenched, tempered, straightened, stress relieved, and cleaned bar

SPECIAL REQUIREMENTS of 32CrmoV12-10 forged material: Material may be ingot or strand cast. If strand cast, material must undergo a minimum reduction in area of 10:1 between the cast and finished diameters. Strand cast material must be cast vertically, saw cut, and tilted to horizontal, i.e., it must not travel around a curved radius when transitioning from vertical to horizontal while cooling. Premium quality bar, 100% tested for
internal and surface defects. Material must pass slit test to measure residual stress after stress relief. Material must measure < 3 Gauss for residual magnetism

GRAIN SIZE of 32CrMoV12-10 forged bars : ASTM grain size # 6 or finer

MECHANICAL PROPERTIES of 32CrMoV12-10 forged parts: YS = 150 KSI min; UTS = 175 – 190 KSI; Elongation = 12% Min.; ROA = 50% min.

MICROSTRUCTURE of 32CrMoV12-10 forged material : Entirely martensitic throughout; partial decarburization <2% of bar diameter, no complete decarburization allowed

CLEANLINESS of 32CrMoV12-10 forged parts: Per AMS 2300, and DIN 50602 K4 <10

IMPACT STRENGTH of 32CrMoV12-10 forged parts: Average longitudinal Charpy “V” notch impact strength when heat treated to 38-41 HRC and tested at minus 40°F = 40 ft.-lbs. min. No individual value less than 35 ft.-lbs. Base of notch to be located at a diameter of .200 - .300”

SURFACE DEFECTS: 32CrMoV12-10 forged Bars must be 100% ultrasonic tested per ASTM E2375, class “A”; and certified free from cracks, seams, folds, laps, pipe, etc.

STRAIGHTNESS of : Special straightness required, i.e. < 1/8” in any 5 feet

TESTING & CERTIFICATION of 32CrMov12-10 forged bars : Testing to be performed on material representing the beginning, middle, and end of each heat. One copy of the original mill certificate, stating country of origin, must accompany each lot.
Certificate must certify material was produced to the required spec., list process sequence including times and temperatures, state reduction ratio, and report actual test results for chemistry, hardness, mechanical properties, impact strength, grain size, cleanliness, decarburization, surface defects, straightness, and slit test
