Quick Answer
For hammer axe forging, the best materials are high-carbon steel, such as 1095 or W2, due to their high hardness and durability. A combination of carbon content and alloying elements like vanadium or tungsten also helps achieve the desired characteristics.
Choosing the Right Steel
When selecting steel for hammer axe forging, consider the carbon content and alloying elements. High-carbon steels like 1095 (0.95% carbon) or W2 (1.5% carbon) are ideal due to their high hardness, wear resistance, and ability to hold a sharp edge. For a more durable axe, consider alloys with vanadium or tungsten, which improve impact resistance and toughness.
Forging Techniques
To successfully forge a hammer axe, use a combination of hot and cold forging techniques. Heat the steel to around 2000°F (1093°C) to make it malleable, then hammer it into the desired shape using a combination of flat and ball-peen hammers. After forging, quench the steel in water or oil to achieve the desired hardness and edge retention.
Tempering and Finishing
After forging, temper the steel to achieve the optimal balance between hardness and toughness. A tempering temperature of 400-500°F (204-260°C) is suitable for most hammer axe applications. Finally, apply a heat treatment or sharpen the axe to achieve the desired edge sharpness and performance.
