High Strength Heat Treated Heavy Steel Forgings For Rolling Mill Transmission Gear. Our high strength heat treated heavy steel forgings are engineered for the most demanding industrial power applications, where structural integrity, fatigue resistance, and load-bearing performance are critical. Produced through open die forging and advanced heat treatment processes, these components offer exceptional mechanical properties and long-term reliability in harsh operating environments.
High Strength & Toughness: Enhanced through quenching and tempering to ensure excellent resistance to mechanical stress and deformation.
Large Section Capability: Suitable for large-scale components used in turbines, generators, press frames, and heavy-duty gear systems.
Refined Grain Structure: Forging ratio ≥ 3.0 provides uniform grain flow, increased fatigue life, and reduced internal defects.
Thermal Stability: Optimized for performance in high-temperature or cyclic thermal environments typical of power generation equipment.
Custom Geometry: Supplied as rough-machined blanks tailored to client drawings and project-specific requirements.
Steam and gas turbine support components
Power plant generator shafts and bearing housings
High-load frames for industrial presses and energy conversion units
Structural parts for energy infrastructure equipment
