A2 is an air hardening(cold work) Tool steel with wear properties between O1 oil hardening and D2 air hardening.
A2 offers good toughness with medium wear resistance along with relatively easy machining.A2 also has excellent non-deforming properties. These characteristics have made A2 a very popular and widely used material.
A2 has a machinability rating of 65% of a 1% carbon Tool steel.
A2 is sold in the annealed condition. Typical annealed hardness is BHN 197/241 Rc 12/22.
A2 maximum working hardness is BHN 698 Rc 62
A2 is capable of meeting ASTM-A681.
 
Typical Applications:
Blanking dies, coining dies, forming die,s trim dies, punching dies, drill bushings, gauges,laminations dies

Machining performance

Principal Design Features

One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.

Machinability

Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.

Heat Treatment

CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.

Welding

Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.

Forging

Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
