Can A2 tool steel be case hardened? [Solved] (2022)

Can A2 tool steel be case hardened?

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.... read more ›

How do you harden A2 steel?

Preheat slowly to 1350-1450°F and hold at this temperature until part is uniformly heated. After thorough preheating, heat to 1750-1800°F. Hold the workpiece at the hardening temperature until it is completely and uniformly heated. A2 is an air hardening steel and will develop full hardness on cooling in still air.... continue reading ›

What's the difference between A2 and D2 steel?

A2 and D2 are cold work tool steels defined by their extremely high hardness after heat treatment. 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.... see more ›

Can cold rolled steel be hardened?

It depends on what type of steel it is. Cold rolled just refers to how it was worked at the mill, not what alloy it is. Some cold rolled steels are hardenable, others are not. If it is hardenable (high enough carbon content) heat it to about 1500 degrees (bright red color ...... view details ›
