Main Shaft Alloy Steel Forgings For 17CrNiMo6 4140 4340 Mining Machinery And Manufactuing

Quick Detail:

1. Forged shaft: Open die forging: Main Shaft, construction and mining machinery parts/shaft
2. Good service, high quality, short delivery time
3. Materials: Alloy steel, carbon steel, stainless steel


The forging process can create parts that are stronger than those manufactured by any other metalworking process. you'll rarely see forgings, as they are normally component parts contained inside assembled items such ships, oil drilling equipment, engines reducer mining machinery roller and all kinds manufacturing equipment.
It main material could be alloy steel, carbon steel or other kind of material as per the clients’requirements.
It conforms to the standard of ASTM, EN, DIN, GB.
The manufacturing equipment is 60MN hydraulic press, the forging ratio >3.
