A2 Tool Steel is a versatile, air-hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment. A2 is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.

What is A2 steel good for?

A2 steel bar is available in a several forms, including square, round, and rectangular. This highly versatile material can be used for a wide variety of tools that require wear resistance, such as industrial hammers, knives, slitters, punches, tool holders, and woodworking cutting tools.

Does A2 tool steel rust?

Does A2 steel rust? Yes, A2 steel composition has only 5.5% of chromium, which grants him good rust protection but it’s not completely immune.

What’s the difference between A2 and D2 steel?

A2 tool steel is often regarded as a “universal” cold work steel, offering a combination of good wear resistance and high toughness. D2 tool steel is harder and more wear-resistant, but less tough. Both can be used for cutting and forming tools, or other applications where high hardness are valued.

How hard is A2 tool steel?

A2 tool steel properties

It’s highly wear-resistant and moderately tough. Like D2, it is incredibly resistant to distortion during heat treating and is moderately machinable and grindable. Popular hardness ranges for A2 run between 57 – 62 HRC with a yield strength range between 185 ksi – 230 ksi.

Is A2 easy to sharpen?

Despite A2’s excellent edge-holding ability, I find it easier to sharpen than CPM 3V. The harder and tougher the steel, the more difficult it is to sharpen. I have sharpening OCD, though, and I maintain knife edges. But if my A2 knife has been used at all, a quick strop is all it ever needs to maintain a wicked edge.

Is A2 tool steel any good?

A2 has good toughness, better than many high wear resistance steels. It also offers great ease in grinding and polishing for the knifemaker, and ease in sharpening for the end user.

Is A2 steel hard to sharpen?

A2 steel takes a little more effort to sharpen, but you are rewarded with a more durable edge that lasts longer. As a person who uses a lot of exotic hardwoods and doesn’t enjoy sharpening any more than I have to, I prefer A2.

Is A2 steel better than 1095?

In most of the “hard use” applications where these two steels are chosen for production knives,”all things” are not equal. Some of the 1095 “tough” knives are left as soft as 55Rc, whereas A2 tend to be in the “58-60” range with 60Rc generally considered to be the “sweet spot” for knife use.

Is A2 a stainless steel?

Both A2 and A4 grades are classed as Austenitic stainless steel (sometimes called the 300 series). This means that they have high chemical resistance but cannot be hardened by heat treatment.

What is an advantage of 1 steel might have over a 2 steel?

You can keep working instead of sharpening. A2 is a great steel that offers a real improvement in edge retention. O1, on the other hand, is still preferred by many for its relative ease of sharpening and its ability to get sharper.

Is A2 a high carbon steel?

Description: A high carbon alloy steel. A2 is known for taking a very fine keen edge. The chromium provides some corrosion resistance.

What is the toughest tool steel?

The hardest and therefore the most abrasion resistant carbides typically found in tool steels are the vanadium carbides.

What is the best steel for tools?

O-1 is an oil-hardening steel with high hardness and good machinability. This grade of tool steel is mainly used for items like cutting tools and drills, as well as knives and forks. A-2 is an air-hardening steel containing a medium amount of alloying material (chromium).

What are the different grades of tool steel?

There are six groups of tool steels: water-hardening, cold-work, shock-resistant, high-speed, hot-work, and special purpose. The choice of group to select depends on cost, working temperature, required surface hardness, strength, shock resistance, and toughness requirements.

Can A2 be forged?

Forging: Heat the A2 slowly to 700°C then more rapidly to 1050-1100°C. Avoid working below 900°C. Reheat as often as necessary to maintain proper forging temperature.

Can you oil quench A2 steel?

After that the answer is yes you can oil quench, you can get even harder by using cryo after the quench, and then you shouldn’t temper using your torch, you should use a kitchen oven or a toaster oven, using a separate oven thermometer to check your temperature.

How do you temper A2 tool steel?

Hardening Tools made from A2 tool steel may be hardened by placing them in a furnace maintained at a temperature of 1725/1775°F (940/969°C). Let the tools heat naturally to the furnace temperature, soak for 20 minutes plus 5 minutes per inch of thickness and air quench.
