Product Description 

Why choose us?

1. High Density for Enhanced Wear-Resistance: To withstand the rigors of high-strength operational environments, our experts carefully select premium-grade alloy steel ingots to forge the chisels. This results in a higher material density, thereby significantly increasing the wear-resistance and durability of the tool.

2. Enhanced Toughness Through Advanced Heat Treatment: The resilience of the steel chisel is crucial to its performance. Our specialists ensure this by subjecting the raw material to precise normalizing processes that yield well-distributed and fine-grained pearlite structures. This treatment grants the chisel exceptional comprehensive mechanical properties, including improved toughness.

3. Superior Wear-Resistance via Segmented Quenching and Tempering: We employ state-of-the-art segmentation quenching and tempering techniques to enhance the hardness and wear-resistance of our steel chisels. Additionally, we utilize imported high-quality quenching media to further bolster these characteristics.

4. Extended Service-Life: By choosing only top-notch, refined alloy steels and refining our quenching medium, our experts are able to guarantee a longer service-life for our chisels. The core hardness of these tools surpasses industry averages by 50%, ensuring they remain effective and efficient over an extended period.

5. Reduced Breakage-Rate through Rigorous Quality Control: Understanding the importance of reliability, we maintain an exceptionally low breakage-rate through meticulous quality control. Raw materials undergo strict scrutiny before processing, production processes adhere to stringent standards, and each product is thoroughly tested to minimize the likelihood of breakage during operation. This thorough approach guarantees a consistently lower breakage-rate, providing customers with peace of mind and cost-effectiveness over time.
