4. AISI/ASTM A681 D2 Grade Steel Forging
Heating for forging of AISI D2 tool steel should
be done slowly and uniformly. Soak through at 1850°-1950°F and reheat as often
as necessary, stopping work when the temperature drops below 1700°F(926℃). After D2
die steel forging, cool slowly in lime, mica, dry ashes or furnace. AISI D2 steel
should always be annealed after forging.
5. D2 Tool Steel Heat Treatment
ASTM D2 steels alloy should be preheated very slowly to 815oC (1500oF) and then temperature can be increased to 1010oC (1850oF). They are then held at 1010oC (1850oF) for 20 to 45 minutes and air cooled (air quenched).
Annealing of D2 tool steels material should be done at 871 to 898oC (1600 to 1650oF) followed by slow furnace cooling at 4.4oC (40oF) per hour or less.after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
When desirable to relieve the strains of machining, heat D2 grade steel slowly to 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving).
Preheat Prior To Hardening
Preheat slowly to 1350°-1450°F and hold at this temperature until grade steel D2 material is uniformly heated.
After thorough preheating, heat to 1800°-1850°F. Hold the work piece at the hardening temperature until it is completely and uniformly heated.
AISI D2 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization of the work piece surface, controlled atmosphere or vacuum furnaces are recommended. If these furnaces are not available, pack hardening, salt baths or wrapping the piece in stainless steel foil will provide some degree of surface protection in the hardening process. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately.
The tempering temperature on material D2 steel may be varied according to the desired hardness. D2 steels can be tempered at 204oC (400oF) for achieving Rockwell C hardness of 61 and at 537oC (1000oF) for a Rockwell C hardness of 54.
6. D2 Tool Steel Material Application
AISI grade D2 tool steels are used for long run tooling applications, where wear resistance is important, such as blanking or forming dies and thread rolling dies.
Some main applications for D2 tool steel are as below:
Blanking Dies, Forming Dies, Coining Dies, Slitting Cutters, Heading Tools, Long Punches, Forming Rolls, Edging Rolls, Master Tools, Beading Rolls, Intricate Punches, Extrusion Dies, Drawing Dies, Lamination Dies, Thread Rolling Dies, Shear Blades, Burnishing Tools, Gauges, Knurls, Wear Parts.

Ice Qubes’ Hazardous location line is designed for purged and non-purged enclosure systems with product offerings including:
• Class 1 Division 1 units available in 14,000 BTU capacity.
• Class 1, Division 2, available in 2,000 to 27,000 BTU capacity.
• Zone 1 & 2 Air Conditioners available in 4500 to 9500 BTU capacity.
Our Class1 Division1 Groups C & D units are UL recognized when used in conjunction with a Type X purged and pressurized enclosure only.
Our Class 1 Division 2, Groups B,C, & D units are third party certified by UL, ETL, and CSA. These units are designed for purged and nonpurged enclosure systems.
Our Zone 1&2, 2 B+H units are IECEx and Atex third party certified by UL and Demko. These units are also designed for purged and nonpurged enclosure systems.
These air conditioners are the perfect solution for all your enclosure cooling needs in the gas, oil, chemical, and other hazardous location industries.
Our hazardous locations line of air conditioners are available in powder coated steel, 304 stainless steel, and 316 stainless steel. Voltages include 120, 230, and 480 volts AC. Select units are available in 50 Hz, some in 60 Hz, and others in dual 50 & 60 hz operation.
All units have the following features:
• Durable 16 gauge welded steel or stainless steel construction.
• Built in condensate evaporation package.
• Easy pull-out filter.
• Efficient, quiet, and long lasting rotary compressors.
• Space saving and aesthetic cabinet design.
In addition, all units are 100% factory tested before leaving Ice Qube’s facility, and all certification certificates are available on our website.
Typically, other manufacturers of enclosure cooling systems send their standard air conditioners to be converted for hazardous location use. These non-oem conversions may make changes that can affect the efficiency and performance of the original unit. These conversions typically carry self-certifications.
Why take that risk? Insist on third party certified air conditioners from Ice Qube.
Ice Qube is the first in the industry to design and manufacture a certified line of hazardous locations air conditioners.
Demand the best for your customers and yourself! Look for these certifications on your air conditioners: ATEX, IECEx, UL, ETL, and CSA Certified Hazardous location Air Conditioners from Ice Qube Cooling Solutions.
