INCH PINS, SLEEVES, BLADES INCH Core Pins – H13 – Standard Medium Hardness
•
Precision made of superior quality hotwork die steel standard hardness 38-42HRC
• Heads are hot-forged for uniform grain flow, higher tensile strength, then annealed to permit easier machining and stamping • +.0008"/+.0003" tolerance on pin diameter ensures a close fit for coring purposes
• •
Pin body and head are finish ground
Centerless ground and polished outer diameter

Hardness checking guidelines
150 Kg. C scale load.
60 Kg. A scale load.
NO
YES
If checking hardness of core pins, do not use method “NO” above, since it will provide an inaccurately low reading. The preferred method is to stand the pin on its head and check the cut end using the A scale, 60 Kg. load as shown above. PRECAUTIONS: The cut end must be parallel to head end, with stem length of 2" minimum. Use cutting fluid to avoid overheating and localized annealing. Position indentation in middle of pin diameter.
C41M_*_ 3/4 (.7500) .250 † Heads of 3"-length pins are not annealed. If annealed heads on 3"-length pins are required, they must be special ordered. (Alternately, you may purchase 6" pins and cut to required length.) 1.000
