How hard do axes need to be tempered?

Most steels need to be tempered at about 450°F for maximum usable hardness but every steel is slightly different. Most axes are heat treated at the bit end only. On many older axes you can see a clear demarcation between the steel that has been hardened at the bit and the softer steel making up the remainder of the axe head.

What is “True Temper?

We know that “tempering” is an important stage in axe making. It must be important for one brand to be called “True Temper,” companies like Emerson & Stevens to emboss the initials of the temperer right on the axe, and many companies to highlight tempering in their ads and labels. Tempering is only one step in heat treating steel though.

Are axe heads heat treated?

Most axes are heat treated at the bit end only. On many older axes you can see a clear demarcation between the steel that has been hardened at the bit and the softer steel making up the remainder of the axe head. This is called the “hamon line.”

What is the purpose of tempering steel?

Tempering is simply raising the temperature of the hardened steel to reduce the stress in the steel caused by heat treating. This reduces the hardness a little, but reduces the brittleness a lot. Most steels need to be tempered at about 450°F for maximum usable hardness but every steel is slightly different.

Should an axe be sharp?

An axe should be kept sharp, given the provision that it has the proper edge geometry. Simply put, a convex edge is going to be stronger than your standard “v” edge.

Are axe heads heat treated?

Most axes are heat treated at the bit end only. On many older axes you can see a clear demarcation between the steel that has been hardened at the bit and the softer steel making up the remainder of the axe head. This is called the “hamon line.”

What is the best axe for cutting wood?

If one wants an axe that will cut across the grain dry hardwoods and without relying on an over obtuse grind, get an upmarket axe with a forged-in tough tool steel edge that can safely be hardened to around 60 HRC and forget 1055, the lowest common denominator for tools of this kind.

How to harden an axe head?

There is a well known knife-maker who discovered a very simple and fast way to harden and temper his axe heads. He was on the phone telling another smith how you can just heat the head and quench the tool and let the latent heat bleed back into the edge...and never have to do anything else.

The roofing axe has small handles that can easily be carried to the rooftop for work. The handles come with both wooden and steel materials and are easily available in the market. Not for heavy splitting tasks What is an AXE head called? The part of the bit that descends from the rest of the axe head is called the beared.

What is tempering in steel?

Tempering is a heat treatment process that alters the mechanical properties (typically ductility and hardness) and relieves internal stresses of a steel. Tempering allows carbon trapped in a martensitic microstructure to disperse, and enables the internal stresses to be released from the steel that may have been created from prior operations.

What metals can be tempered?

While there are many different metals that can be tempered, steel is valuable for its strength and resistance. Once you’ve selected your grade and steel or another iron-based alloy, the process of tempering steel begins with extreme heat.

What are the advantages of tempering?

1 Tempering is most commonly used following a quenching operation. Heating a carbon steel and rapidly quenching it can leave it too hard and brittle. ... 2 Tempering can reduce the hardness and relieve the stress of a welded component. ... 3 Work hardened materials often require tempering. ...

What do the different colors of tempered steel mean?

The various colors produced indicate the temperature to which the steel was heated. Light-straw indicates 204 °C (399 °F) and light blue indicates 337 °C (639 °F). Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.
