Selection of high chromium alloy hammerhead materials for pile driver


The high chromium alloy hammer head of pile driver undertakes collision damage and drilling damage in different levels in the application. The provisions of high wear resistance and high toughness are clearly proposed for the applied materials. Therefore, when selecting materials, the manufacturer of hydraulic pile hammer must fully grasp the load standard and working scheme, and effectively use the materials. There are usually several choices:


1. Forging high chromium alloy hammer head: the high chromium alloy hammer head of forging pile driver is made of high-quality train wheel rim steel with 63mn raw material, which has strong impact resistance, strong ductility, good wear resistance and is not easy to fracture. High chromium alloy hammerhead is suitable for crushing pebble, gangue brick and dolomite. Forged high chromium alloy hammerhead is favored by many customers due to its low price, economic development and durability.


2. High manganese steel hammer head: high manganese steel hammer head has good ductility, good process performance and low price, which is mainly used for crushing dolomite and iron ore sand. However, the high chromium alloy hammer head of high manganese steel pile driver has higher requirements on the overall characteristics of the pile driver. If the physical impact force is insufficient or the contact stress is small in specific work, it is not allowed to make the surface layer rapidly cause cold work hardening, and then give full play to it It doesn't have the wear resistance it needs.


3. High chromium alloy hammer head: high strength and high cobalt alloy hammerhead are of high quality and low ductility. They are very easy to crack without the support point of hammer frame. High chromium compound hammer head is suitable for crushing high toughness raw materials, such as artificial quartz stone, limestone, etc. However, the production process of alloy hammerhead is very high.


4. Tungsten steel high chromium alloy hammer head: compared with other materials, tungsten steel high chromium alloy hammer head has higher strength, tensile strength and impact resistance, heat resistance and fatigue characteristics, good thermal strength and low cost. It can deal with the problems of cracks, desoldering, chipping and block dropping of high manganese materials, and has excellent impact resistance and thermal shock resistance of mechanical equipment. Luoyang high chromium alloy hammers are widely used in many fields, most of which can be integrated into all the foundation piling manufacturing industry.
