How strong is A2 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.
What Rockwell is A2 tool steel?
60-62 HRC
A2 tool steel is typically hardened to 60-62 HRC and then tempered to final hardness.
What is A2 steel equivalent to?
Equivalent materials to A2 tool steels are: AFNOR Z 100 CDV 5. DIN 1.2363. JIS SKD 12.
What is the tensile strength of tool steel?

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. For our high carbon steel blades, HOCK TOOLS uses AISI (American Iron and Steel Institute) O1, a simple high carbon tool steel with very little added to the iron/steel alloy other than 1.1% manganese.
Is A2 a good steel?
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.
Does A2 tool steel rust?
While “stainless” amounts of chromium (12% or more) make tool steel “gummy” and hard to sharpen, the modest amount of chromium in A2 improves its toughness and abrasion resistance, but imparts only a slight measure of corrosion resistance (like high carbon steel, it will rust and appropriate preventative care must be …
Can you oil quench A2 steel?
Yes,AIR COOL the A2. Don’t let anyone tell you different. A2 is an AIR HARDENING STEEL. Quenching it in any medium will cool it too fast,and could cause warping or cracking,and also screw up the molecular structure of the steel.
Is A2 tool steel good?
A2 steel Toughness The A2 steel offers great toughness! The steel is even tougher than steel grades like D2. Knives with A2 hardly chip, crack or break, with repeated heavy-duty use. Thanks to this high toughness, A2 has remained a top choice for die steel for many years.
How hard is A2 tool steel?
How hard is annealed A2 tool steel?
Annealing: Soak thoroughly at 840-850°C, then slowly furnace cool at a rate of not more than 20°C per hour. After annealing A2 a maximum hardness of 215 Brinell may be achieved.
Is A2 steel tough?
What is the hardness of A2 tool steel?
AISI A2 tool steel is a 5% chromium medium alloy cold work tool steel possessing sufficient hardenability to be air hardened to 60 Rc surface hardness level with good depth of hardening.
What is the hardness of A2?
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.
What are the characteristics of tool steel?

What are properties of tool steel?
Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Its hardness, resistance to abrasion and ability to retain shape at increased temperatures are the key properties of this material. Tool steel is typically used in a heat treated condition which provides increased hardness.
