Heavy Steel Forgings For Marine Propeller Shaft Manufacturing

Heavy Steel Forgings for Marine Propeller Shaft Manufacturing

Our heavy steel forgings for marine propeller shafts are engineered to withstand extreme operating conditions in marine environments, offering exceptional strength, toughness, and fatigue resistance. Produced from high-quality alloy steels such as 42CrMo, 34CrNiMo6, and 18CrNiMo7-6, each forging undergoes precise temperature-controlled forging, quenching and tempering, and rigorous ultrasonic inspection to ensure uniform internal quality and superior mechanical performance.

Product Features

• High tensile and yield strength to endure continuous torque and thrust

• Excellent impact toughness and resistance to fatigue under cyclic marine loads

• Optimized grain structure through controlled forging and heat treatment

• Strict quality control including UT, hardness testing, and metallographic inspection

• Available in customized dimensions to meet specific vessel and engine requirements

Applications

• Marine propeller shafts for commercial ships, cargo vessels, and naval ships

• High-load rotating shafts in offshore platforms and ship propulsion systems

• Industrial heavy-duty shafts in power transmission systems where corrosion resistance and mechanical reliability are critical
