Nickel-Containing Chisels for Hydraulic Hammers

In the industry of manufacturing and selecting tools for hydraulic hammers (breakers), the quality of raw materials and the production process play a decisive role in the tool’s performance and lifespan. Nickel-containing chisels for hydraulic hammers refer to a category of chisels in whose alloy steel composition a specific amount of nickel has been used. The addition of nickel as a key alloying element significantly improves the mechanical properties of the steel, leading to the production of chisels with higher resistance to harsh working conditions and severe impacts.

The Role of Nickel in Enhancing Steel Properties of Hydraulic Chisels

Nickel is one ofthe most important alloying elements used to improve the properties of steels for impact tools like hydraulic hammer chisels. The main reasons for its importance are:

• Increased Toughness and Impact Resistance in Nickel-Containing Chisels The most significant effect of nickel is a dramatic increase in the steel’s toughness. Toughness refers to the material’s ability to absorb energy and resist fracture under impact. A nickel-containing chisel, due to its higher toughness, exhibits better resistance to cracking and sudden failure caused by the heavy and numerous impacts of a hydraulic hammer. This property is particularly maintained even at lower temperatures.

• Improved Hardenability and Strength Nickel increases the hardenability of steel. This means that during the heat treatment process, a more uniform and deeper hardness can be achieved throughout all parts of the chisel, even in thicker sections. Additionally, nickel helps to increase the tensile strength and yield strength of the steel without significantly reducing its ductility.

• Increased Fatigue Resistance in Nickel-Containing Chisels Hydraulic hammer chisels are subjected to millions of loading and unloading (impact) cycles. Nickel, by improving the internal structure of the steel, increases its resistance to fatigue, thereby contributing to the longer service life of nickel-containing chisels for hydraulic hammers.

Impact of Nickel on Performance and Lifespan of Hydraulic Hammer Chisels

The use of nickel-containing steels in manufacturing hydraulic hammer chisels leads to the following practical benefits:

• Reduced probability of premature chisel failure and increased work safety.
• Increased intervals between chisel replacements, consequently reducing maintenance costs and equipment downtime.
• More reliable performance in tough working conditions and when dealing with highly resistant materials.
• Better wear resistance in some specific alloy compositions, although other elements like chromium and molybdenum play a more primary role in wear resistance.

Nickel-Containing Chisels and Various Shapes

It is important to note that “being nickel-containing” refers to the chemical composition of the steel used to make the chisel, not its geometric shape. Therefore, various types of chisels such as moil points, wedge tools (flat or spade), blunt tools, and other special chisels can be made from nickel-containing steels to benefit from the aforementioned advantages.

Importance of Complete Alloy Composition and Heat Treatment Alongside Nickel

Although nickel is a very beneficial element, the final quality of a nickel-containing chisel for hydraulic hammers does not solely depend on its presence. The exact percentage of nickel, the presence and ratio of other alloying elements (such as chromium, molybdenum, manganese, vanadium), the quality of the steel melting and casting process, and most importantly, the precision and correctness of the subsequent forging and heat treatment processes (hardening and tempering), all play a fundamental role in achieving optimal mechanical properties and superior chisel performance.

Conclusion: Why Choosing Nickel-Containing Chisels for Hydraulic Hammers is Important?

Choosing nickel-containing chisels for hydraulic hammers from reputable manufacturers who use high-quality alloy steels and controlled production processes is a smart investment to increase productivity, reduce operational costs, and ensure safety in demolition and excavation projects. By offering a superior combination of strength, toughness, and fatigue resistance, these chisels will be a reliable partner for your hydraulic hammer in the toughest working conditions.
