The primary alloy carbides in Vertex are smaller than the large chromium-rich alloy carbides which are characteristic of D2 tool steel. These smaller carbides result in better impact toughness and superior fatigue properties compared to D2 .D2 steel is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition.2.2. Air-hardening; The first air-hardening grade tool steel was mushet steel, which was known as air-hardening steel at the time. Modern air-hardening steels are characterized by low distortion during heat treatment because of their high-chromium content.

D2 Air Hardening Tool Steels

Nitriding develops the highest hardness on an alloy nitriding steel substrate; boronizing, vanadium carbide, and titanium car- bide treatments are often performed on air - hardening tool steels such as AISI Type D2 that will air-harden on cooling from the process temperature.

D2 Tool Steel. The popular tool steel which is considered to be a High Carbon High Chromium Cold Work tool steel is known by the international designation of D2 and is a very popular tool steel that can be used for many applications.Air-Hardening A2 Tool Steel Rods Hardened for increased abrasion and impact resistance, these rods are precision ground with a tight diameter tolerance. Multipurpose Oil-Hardening O1 Tool SteelD2 is a high carbon - high chromium air hardening tool steel, heat treatable to 60-62 Rc. D2 offers excellent wear and abrasion resistance, due to large volumes of carbides in the microstructure. D2 is widely used in long production cold work applications requiring very high wear resistance and high compression strength.

Cold Work Tool Steel

D2 Tool Steel. D2 Tool Steel is a high carbon – high chromium air hardening tool steel, heat treatable to 60-62 Rc.

a slight amount of contraction after hardening with the part in the asquenched condition or tempered below OWE Tempering at approximately 925T usually eliminates this contraction and brings the part virtually back to its original size. D2 has the least distortion in heatApr 19, 2010  D2 is a high carbon tool steel, so you will need to protect against decarburizationn with a protective atmsophere, as mentioned above, or in vacuum or a salt bath. Also, a double temper is recommended, perhaps a cryogenic treatment in between tempers. You might consider a nitriding surface treatment.Mar 14, 2011  Many clamp it between a couple pieces of thick aluminum, steel or brass to quench it, but, blowing on it gently with cool air will work. I would keep it even on both sides to help keep it from warping. Even a fan should work. D2 will harden if you get it below 1300f in less than 4 1/2 minutes and keep cooling it to room temperature.

All About D2 Steel

Nov 05, 2018  D2 is part of a tool steel category called “high carbon, high chromium” steels. The production of chromium-alloyed steel wasn’t practical until ferrochromium was developed in 1821 and more practically in 1895 with the development of low carbon ferrochromium.

D2 Flat Bar is a rugged tool steel for almost all types of uses when you want to achieve long life from shear blades, planer blades and industrial cutting tools. Hardening D-2 Flat Bar Stock: In a control temperature oven, heat slowly to between 1875-1925°F (788-843°C), and should have a dark yellow color.D2 HIGH CARBON - HIGH CHROME An air-hardening type steel known for its rnaximum wear resistance qualities. It is ideal for use in tools, dies, etc., used in long production runs. More on D2 High Carbon -D2 is a deep hardening, highly wear resistant alloy. It hardens upon air cooling so as to have minimum distortion after heat treatment . 1.2379 AISI D2 tool steel used for long run tooling applications where wear resistance is important, such as blanking or forming dies and thread rolling dies, cutting tools, stamping, woodworking , moulding tools for plastics .

Tool Steels

This pre-hardened, high performance die steel comes to you ready to machine and put into service. It is a modern tool and die steel (similar to a 4330 alloy), made to Clean Steel Production Technology.

American Iron and Steel Institute-grade D2 tool steel is a high-alloy, high-carbon steel developed for additional strength and toughness. The steel has a high chromium content (11 to 13 percent) and relatively high amounts of molybdenum (.7 to 1.2 percent), vanadium (1.1May 29, 2003  this is the link to Crucible tool steel. All you will ever want to know about hardening. Your immediate problem is that to get A2 hot enough to harden you will destroy your silver solder joint. A gentle fan is all that should be used on air hardeneing steel in thin sections unless specifically stated otherwise on the steel spec sheet.Tool Steel D2 Grade Summary: D2 is a high carbon, high chromium, air-hardening tool steel. It was formulated to combine excellent abrasion resistance and air-hardening characteristics and has become the tool and die standard against which other tool steels are measured for abrasion resistance, dimensional stability in hardening and air-hardening characteristics.

Tool Steel Square Bar D2 is a high-carbon, air-hardening tool steel that provides good resistance to wear. D-2 provides a good blend of toughness, strength, and affordability.

Cold Work Tool Steel D2. Cold Work Tool Steel Round Bar is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening.
