Larger diesel engines are being adopted to improve fuel consumption and lower exhaust gas emissions, along with large propellers that rotate at slower speeds. Necessarily, larger crankshafts are needed to link the engine pistons to the propellers.

Near-Net-Shape Steel Forging for Large Crankshafts

Die forging allows Kobe Steel to produce high-strength, lighter weight components with an approved, 5% margin in fatigue strength in the design phase. Diameters of 80 cm, or more 5% greater fatigue strength Certified producer for all throws

Kobe Steel Ltd. is a forger like none other: its methods are heavily researched and its products are highly engineered, filling an indispensible role in the much broader definition of the industrial group. Its forgings may be found in automobiles and trucks, commercial aircraft and power plants.

And sailing the high seas. Several years ago Kobe Steel Ltd. developed a novel forging technique for manufacturing large-dimension crankshafts used in diesel marine engines.
