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.

Painting heating pipes. Protect your heating pipes and save money… Protect your heating pipes from corrosion and oxidation for years to come. COATING 51 by Gilbert Geraerts offers you improved heat and light output. This combi paint (red lead steel primer and topcoat combined into one) is ideal for greenhouses. Fast, easy and safe to use. Suitable as a primer and topcoat, for heating pipes, growing tubes, hoistable heating frames and other ironwork and structures. High covering capacity, resistant to moisture and high temperatures and safe for your crops. Safe, provided used judiciously. Processing of this pipe & tube paint is easier than ever. COATING 51 has been developed by Geraerts, in collaboration with a specialised manufacturer. Our standard white paint is specially coloured, and has a blue glow, which ensures a brighter appearance and excellent covering capacity.
The advantages of pipe coatings:
- White tubes provide up to 55% more light reflection, and more heat output of approximately 10%
- COATING 51 is a primer and topcoat in one, with a high level of rust-proofing.
- More environmentally friendly process and product
COATING 51 is low in aromatic compounds and harmless to crops after through-drying. When manually painting, one can choose between one or two layers. For maintenance purposes, a single layer is almost always enough. Painting the tubes by hand is usually done with a washcloth or painter’s mitt. COATING 51 is a satin finish tube coating with active anticorrosive pigments. COATING 51 is suitable for both maintenance work and the painting of new pipes. Because COATING 51 possesses the hardness of a topcoat, combined with red lead, each layer is rust proof. COATING 51 is a high quality red lead steel primer and provides protection for years to come. The product has been designed exactly for this type of application and application technique. The product is available in a 20-litre package. The washcloth and paint glove are available in pairs.
