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

Category Details
Materials 42CrMo, 34CrNiMo6, 18CrNiMo7-6, and other high-strength alloy steels — engineered for excellent toughness, seawater corrosion resistance, fatigue endurance, and low-temperature impact toughness, meeting the demanding requirements of marine propulsion applications.
Forging Equipment 5T / 8T / 12T Hydraulic Hammers and Ring Rolling Mills — capable of producing large-diameter, long-length propeller shaft forgings up to Ø1500 mm and 6 meters in length, ensuring uniform internal structure and superior fiber flow along the shaft axis.
Production Process Raw Material Confirmation → Open Die Forging → Heat Treatment (Quenching & Tempering) → Rough or Finish Machining → Dimensional & NDT Inspection — ensuring refined grain structure, stable mechanical strength, and accurate geometry for critical propulsion components.
Forging Ratio ≥ 3.5 — guaranteeing improved grain refinement, high torsional strength, and excellent resistance to alternating loads and thrust stresses in ship propulsion systems.
Application Designed for marine propeller shafts used in commercial vessels, bulk carriers, and naval ships. Also applicable for thruster shafts, intermediate shafts, and propulsion system components in offshore and deep-sea environments.
Delivery Condition Quenched and Tempered; available in as-forged, rough-machined, or finish-machined conditions. Stress-relieved to ensure dimensional stability and alignment during assembly and operation.
Inspection & Testing Equipment • Chemical Analysis: Spectrometer • Mechanical Tests: Tensile, Impact, Hardness • NDT: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) • Dimensional Control: Coordinate Measuring Machine (CMM), Precision Gauges • Metallography: Grain size, inclusion rating, and microstructure verification
Full-Cycle Service End-to-end manufacturing support covering forging, heat treatment, CNC machining, testing, quality documentation, and export logistics. All processes are performed under ISO, EN, ASTM, and IACS standards, ensuring reliability and long service life of marine shaft forgings.
