S355 St52 Precision Machined 4 Meter Forged Gear Blank

The S355/St52 Precision-Machined 4-Meter Forged Gear Blank is a high-quality industrial component engineered for heavy-duty machinery. Manufactured from S355/St52 steel, it delivers excellent strength, toughness, and wear resistance. Precision machining ensures tight tolerances and smooth surfaces, making the blank ideal for subsequent gear-cutting or finishing processes. With a 4-meter length, it is suitable for large-scale equipment such as mining machinery, wind turbines, and marine propulsion systems. The forging process enhances mechanical properties, ensuring long-term durability under high stress. This gear blank offers reliable performance for industries requiring precision, high load capacity, and extended service life.

Forged Steel: Grades, Parts, Shafts & When to Choose Forging

Industry News 2026-05-25

What Is Forged Steel? Forged steel is steel that has been shaped by applying compressive force — hammer blows, press tonnage, or die pressure — while the metal is at an elevated temperature, typically between 1,100°C and 1,250°C (2,000°F–2,300°F) for hot forging. The mechanical working breaks up ca...
