Characteristics and description
Steel 60 refers to structural unalloyed special quality steels with a high carbon content (0.60%) and normal manganese content, has high strength and high elastic properties.[1]
Steel is prone to cracks when quenched in water.
Purpose
Steel 60 is used for the manufacture of parts that require high strength and wear resistance, for example:
- Eccentrics,
- solid-rolled carriage wheels,
- tires for rolling stock of broad gauge railways,
- working rolls of sheet mills for hot rolling of metals,
- spindles,
- bandages,
- clutch discs,
- shock absorber spring rings,
- lock washers,
- adjusting washers,
- shims,
- work rolls of sheet mills for hot rolling of metal.
Temperature of critical points, °C [81]
Heat treatment
Small parts made of grade 60 steel (up to 10-12 mm in diameter) are hardened in oil at a temperature of 820-860 ° C, larger parts in water at a temperature of 800-820 ° C, tempering is carried out at different temperatures depending on the required mechanical properties.

Rules of care
There are several rules:
- The metal surface after heat treatment is black. A layer of oxides is formed, which protects the tool from corrosion. You cannot remove blackening with grinding wheels “for beauty”. Only the working edge of the blade should shine after sharpening.
- Before long-term storage, the head is lubricated with oil. Experienced carpenters do not recommend using machine lubricants for this purpose. They use castor, linseed or vaseline oil. After lubrication, wipe the head - a thin film is enough to protect against rust.
- The tool should not lie on the ground, on a concrete floor or stand near a wall for a long time. The geometry of the ax is disrupted. That's why they hang him up. The wooden part is impregnated with oil so that the wood does not dry out.
How to sharpen an ax correctly
In production, cutting edge geometry is developed using a grinder. This is a belt sander. On an abrasive of this shape, a convex cutting edge is more easily formed.
- While working with an axe, it is enough to regularly adjust the cutting edge with a fine abrasive stone. The angle specified during sharpening in production is not violated.
- For universal axes, the sharpening angle is 20-30 degrees, for carpentry tools - 35 degrees. The steel is hard enough to hold an edge for a long time.
- If you need to restore the cutting edge and eliminate chips, use an electric sharpener. A grinder is not suitable for this purpose.
- It is very important to maintain the sharpening angle. They operate at low speeds to avoid beating of the blade and strong heating of the metal. As the temperature rises, the structure of the hardened steel changes and the blade loses its hardness.
- To cool, add water or take breaks from work.

Types of axes
Based on the shape of the head and ax head, axes are divided into universal and special. The universal ones include:
- Economic. A small ax with an almost symmetrical head.
- Army and tourist. Lightweight tools, the head and ax handle are often made from one piece of metal.
- Plotnitsky. Differs in sharpening angle for easy removal from dense wood.
- Russian. Can be used for woodworking and as a throwing weapon
Special axes are used to perform a certain type of work. Examples:
- A splitting splitter for splitting sawn logs along the grain. The head is massive and hardly sharpens.
- Myasnitsky with a short ax and a wide head.
- Lumberjack's axe. It has the longest ax handle, which increases the impact force.
- Firefighter. All-metal with a spike on the butt and heat-protective linings on the axe.
- Roofing. The butt has the shape of a hammer.
- Adze. Designed to remove layers of wood.

Application of steel 60g
The main area of application of low-alloy structural spring steel 60g is the industrial production of springs, springs and other spring-type products. The wear resistance and high elasticity of the alloy are used by technologists in the manufacture of parts such as brake drums, bushings, bandages, and brackets. In general, this alloy is used as a raw material by a variety of heavy engineering enterprises.
Manufacturers of cutting and piercing tools are also interested in the characteristics of 60g steel: knives, axes, cleavers - in such products, 60g alloy is most often used to form the core of the working part of the tool.
