The Rough Machined Crane Wheel in 4140 Alloy Steel Material is engineered for demanding industrial environments where high
strength, wear resistance, and dimensional reliability are
critical. Forged from premium 4140 alloy steel and rough machined
to your specifications, this crane wheel is ideal for heavy-duty
lifting systems that operate under high loads and continuous
cycles.
| Item | Details (4140 Alloy Steel Crane Wheel) |
|---|
| Material | 4140 Alloy Steel – Known for high fatigue strength, toughness, and
resistance to wear and impact under load. | | Forging Equipment | 5T, 8T, 12T Hydraulic Hammers – Ensures uniform deformation and
fine grain structure during open-die forging. | | Application | Specifically designed for port cranes, container handling trolleys, and gantry crane systems. | | Manufacturing Process | Forging + Normalizing & Tempering + Rough Machining – Guarantees structural integrity and mechanical performance. | | Forging Ratio | ≥ 3.0 – Promotes optimal grain orientation for enhanced load-bearing capacity and service life. | | Delivery Condition | Supplied in rough-machined condition, heat treated (normalized
& tempered), with stress relief to maintain dimensional stability during final machining. | | Testing Equipment | Equipped with spectrometer, ultrasonic flaw detector, tensile & impact testers, metallographic microscope, micrometers, bore gauges, and hardness testers to ensure full quality traceability. | | Service Scope | From forging and machining to heat treatment, inspection, packaging, port delivery, and export
logistics. Tiangong Forging provides complete service solutions focused on customer-specific requirements and consistent product quality. |
These are the main inspection equipments: | Our Lab inspection equipment | | 1 | Spectral component analyzer | | 2 | Impact strength testing machine | | 3 | Impact test cryogenic tank | | 4 | Ultrasonic flaw detector | | 5 | Brinell hardness tester | | 6 | Rockwell hardness tester | | 7 | Digital hydraulic universal testing machine | | 8 | H.Metallurgical microscope | | 9 | Program-controlled box furnace |
