ASME S355JR/Q345/ST37 Forged Steel Hydro Turbine Shaft High-Strength Step Shaft for Hydropower

The ASME-grade S355JR/Q345/ST37 forged steel hydro turbine shaft is a high-strength step shaft engineered for hydropower systems. Made from forged carbon steel (equivalent to EN S355JR, ASTM Q345, and DIN ST37), it provides excellent tensile strength, impact resistance, and durability under heavy loads. The precision-machined stepped design ensures proper alignment with turbine components for efficient energy transmission.

With superior weldability, corrosion resistance, and fatigue performance, it is ideal for harsh hydropower environments. Fully compliant with ASME, EN, and DIN standards, it guarantees reliability and long service life. Custom dimensions and heat-treatment options are available to meet specific operational needs.

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...
