High Light | Fatigue Resistant Heavy Steel Forgings ,Alloy Heavy Steel Forgings 100kg ,Mining Excavation Forgings |
Fatigue Resistant Alloy Heavy Steel Forgings for Mining and Excavation Machinery. Designed for extreme operational environments, our fatigue resistant alloy heavy steel forgings offer exceptional structural durability for mining and excavation applications. These forged components are manufactured from high-performance alloy steels and engineered to endure high-impact loads, continuous vibration, and cyclical stress common in heavy-duty earthmoving operations.
Fatigue Resistance: Enhanced forging ratio (≥ 3.0) and refined grain structure significantly improve resistance to crack initiation and propagation under cyclic loading.
Tough Alloy Composition: Forged from alloy steels with optimized strength-to-toughness balance, ideal for resisting shock and abrasion in harsh terrain.
Heavy Section Capability: Available in large dimensions and complex geometries to meet the structural demands of mining loaders, excavators, and drilling rigs.
Rough Machined Supply: Delivered in heat treated and rough machined condition for further processing as per equipment-specific tolerances.
Structural forgings for boom arms, buckets, undercarriage frames, and main bodies of excavators
Load-bearing shafts and couplings in mining shovels, draglines, and rock crushers
Forged parts for drilling rigs, tunneling machines, and ore handling systems
Key transmission and support components in off-highway dump trucks and bulldozers

Product Name | Fatigue Resistant Alloy Heavy Steel Forgings for Mining and Excavation Machinery |
Material Grades | - Alloy steels engineered for high impact absorption, fatigue endurance, and operational durability under cyclic and heavy mechanical loading |
Forging Equipment | - Hydraulic Hammers: 5T, 8T, 12T- Suitable for open die forging of thick-section structural parts for excavators, loaders, and mining equipment |
Manufacturing Process | Raw material inspection → Unloading → Inspection → Preheating → Forging → Heat Treatment → Inspection → Rough Machining → NDT → Final Inspection → Packaging → Delivery |
Forging Ratio | ≥ 3.0 — Enhances grain flow continuity and improves fatigue life and impact resistance under repeated loading in harsh terrains |
Heat Treatment Options | - Quenching + Tempering or Normalizing + Tempering to strengthen core properties and reduce internal stresses |
Applications | - Load-bearing forgings in mining excavators, rock crushers, draglines, drilling equipment- Structural elements in frames, arms, buckets, undercarriages |
Process Compliance | - Produced based on customer-supplied technical drawings and fatigue-critical usage scenarios |
Delivery Conditions | - Heat treated and rough machined, ready for downstream processing- Available in custom sizes and configurations tailored to mining and excavation systems |
Testing & Inspection | - Chemical Composition Analysis- Mechanical Testing: Yield Strength, Impact Toughness, Hardness- NDT: Ultrasonic (UT), Magnetic Particle (MT)- Dimensional Verification using precision tools |
Process flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
