42CrMo, 42CrNiMo Fast Delivery & Stable Quality – Forged Parts for Hydraulic Breakers
We supply high-performance forged parts for hydraulic breakers using premium alloy steels such as 42CrMo and 42CrNiMo, known for their excellent toughness, wear resistance, and impact strength. Our forgings are widely used in rock breakers, demolition tools, and excavator-mounted hydraulic hammers, meeting the demanding requirements of construction and mining industries.
Produced through open die forging, each component undergoes strict heat treatment and ultrasonic testing to ensure internal integrity and dimensional accuracy. We offer both rough machined and CNC precision-finished parts, with fast delivery and stable quality guaranteed by our ISO-certified production process.
OEM customization is available based on your drawings and technical specifications. Our forged parts are trusted by global OEMs for their long service life and superior mechanical performance.
We specialize in the production of high-performance forged parts for hydraulic breakers, engineered to endure extreme impact loads and abrasive conditions commonly found in construction, demolition, and mining operations. Using premium-grade carbon and alloy steels, our forgings are crafted through controlled forging and heat treatment processes, ensuring outstanding strength, wear resistance, and dimensional precision.
With over five years of stable cooperation, we have served as a trusted long-term forging partner to a leading Korean heavy machinery manufacturer. Our components consistently deliver proven reliability and fatigue resistance in high-demand applications, reinforcing our reputation for quality and dependable lead times.
