Can you oil quench A2 steel?

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.

How do you harden A2 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.

How do you quench A2 tool steel?

A2 should always be annealed after forging. Heat slowly to 1550-1600F, hold until entire mass is heated through, and cool slowly in the furnace (40F per hour) to about 1000F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.

How hard can you heat treat A2 tool steel?

A2 tool steel is typically hardened to 60-62 HRC and then tempered to final hardness. I assume the 50 HRC hardness you mention is the result of this process. A (stress-relief) temper in the range of 1100-1200°F (595-650°C) will lower the hardness, but I suspect only into the range of 44-46 HRC.

How good is A2 tool steel?

A2 is a mid-range Air-Hardening tool steel, it’s known for its good toughness (its tougher than D2 Steel or M2 Steel ), and it has a wear resistance in between O1 Steel and D2, it’s used for Punches and dies, chuck jaws, cutting tools for woodworking, tooling for plastic injection, dowel pins, hammers, industrial knives, and gage.

What is the best oil for hardening steel?

Quench Oil is oil used to harden steel by controlling the heat transfer during the quenching process. It is versatile in nature thus it enhances the performance of the quenching process.

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.

Is A2 tool steel hard?

A2 is also an air-hardening tool steel but includes less than half the chromium (4.75 – 5.50%) and a bit less carbon (0.95 – 1.05%) than D2. It’s highly wear-resistant and moderately tough .
