Forged Steel Rings
SCM440 42CrMo4 Hot Rolled Seamless Steel Ring - Precision Slewing Bearing Component
This high-performance steel ring is manufactured from SCM440 (Japanese standard) or 42CrMo4 (European equivalent), a chromium-molybdenum alloy known for exceptional strength, toughness, and wear resistance. Produced via hot rolling, its seamless construction ensures uniform mechanical properties and superior structural integrity—ideal for heavy-duty applications.
Precision-machined to tight tolerances, it serves as a critical component in slewing bearings for construction machinery, wind turbines, and industrial rotating equipment. With excellent hardenability (reaching HRC 28–32 after heat treatment), the alloy offers enhanced fatigue life and load capacity. The seamless design eliminates weak points, ensuring reliability in high-stress environments.
Key features include high tensile strength (≥980 MPa), exceptional impact resistance, and excellent post-treatment machinability.

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...
