|---|---|
| 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. |
Raw material verification → Billet cutting → Controlled preheating → Open-die forging of shaft blank → Post-forging heat treatment → Cooling and surface inspection → Rough machining → Intermediate testing (UT, MT, hardness) → Quenching & tempering (Q&T) → Final mechanical and metallographic tests → Finish machining → Dimensional and visual inspection → Marking, anti-corrosion coating, and packing → Storage and shipment.
