We are professional cold works D2 tool steel supplier for more than two decades. We supply AISI / ASTM A681 cold works D2 tool steels alloy steel materials in reliable quality and for attractive price for sale. We have deep knowledge of D2 tool steel¡¯s chemical composition and properties. Contact us for any D2 tool steel materials demands.
Cold Works D2 tool steel is a high carbon, high chromium tool steel (12% chrome) with extremely high wear resisting properties, heat treatable to 60-62 Rc. D2 steel is very wear resistant but not as tough as lower alloyed steels. D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. The high percentage of chromium gives it mild corrosion-resisting properties in the hardened condition. The mechanical properties of D2 are very sensitive to heat treatment. D2 steel is available in de-carb free rounds, flats, and squares, as well as ground flat stock and drill rod.
D2 Tool Steel Heat Treatment
Heat Treatment
ASTM D2 steels alloy should be preheated very slowly to 815℃ (1500¡ãF) and then temperature can be increased to 1010oC (1850¡ãF). They are then held at 1010oC (1850¡ãF) for 20 to 45 minutes and air cooled (air quenched).
Annealing
Annealing of D2 tool steels material should be done at 871 to 898℃ (1600 to 1650¡ãF) followed by slow furnace cooling at 4.4℃ (40¡ãF) per hour or less.after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Stress Relieving
When desirable to relieve the strains of machining, heat D2 grade steel slowly to 1050¡ã-1250¡ãF, allow to equalize, and then cool in still air (Strain Relieving).
Preheat Prior To Hardening
Preheat slowly to 1350¡ã-1450¡ãF and hold at this temperature until grade steel D2 material is uniformly heated.
Hardening
After thorough preheating, heat to 1800¡ã-1850¡ãF. Hold the work piece at the hardening temperature until it is completely and uniformly h |
