The Differential Heat-Treated Hammer, crafted from medium alloy steel, features a dual-hardness structure designed for optimal performance. The working zone of the hammer boasts a high hardness level of 500-600HB, ensuring resilience against extreme impacts from high-speed metal scrap. Simultaneously, the pin hole area is engineered with a slightly softer hardness of 350-450HB, providing enhanced protection against wear and tear of the hammer pin.
The essence of its manufacturing excellence lies in the sophisticated heat treatment process. This intricate five-step procedure strategically varies the hardness across different parts of the hammer, resulting in a component that is perfectly attuned to its intended application, balancing toughness and durability.
