Ductile Iron Casting Part Series 2
JHshukong
Engineered for maximum strength in heavy-load applications, our Heat-Treated High-Strength Ductile Iron Casting Parts Series 2 deliver unparalleled tensile and yield strength through advanced heat treatment processes. Cast from ASTM A536 Grade 100-70-03 and EN-GJS-700-2, these parts undergo quenching-tempering to achieve a martensitic matrix, ideal for components in construction, mining, and heavy machinery.
Heat Treatment-Driven Strength
Mechanical Excellence:
Tensile strength 100ksi (690MPa), yield strength 70ksi (483MPa), and hardness HB 260-300, supporting static loads up to 40 tons in crane hooks and excavator arms.
Impact resistance 20J (Charpy V-notch at 23°C), balancing strength with ductility to prevent catastrophic failure in sudden load scenarios.
Microstructure Optimization: Quenching in oil/polymer solutions produces fine martensite, reducing brittleness and improving fatigue life (endurance limit ≥450MPa, 10⁷ cycles).
Casting & Processing Precision
Low-Pressure Casting: Reduces porosity and ensures uniform heat treatment response, with wall thickness 10-150mm for heavy-section components.
NDT Compliance: 100% ultrasonic testing for internal defects and hardness mapping (30+ points per part), ensuring heat treatment uniformity (variation ≤5HB).
Surface & Structural Integrity
Shot Peening: Coverage ≥95% on stressed surfaces, increasing fatigue strength by 30% for components like drive shafts and track links.
Machinability: Pre-heat treatment machining allowances (1-2mm) ensure post-treatment dimensional accuracy, with finished surfaces achieving Ra ≤3.2μm.
Environmental Adaptability
Temperature Performance: Operational from -20°C to 200°C, with optional thermal barrier coatings (TBC) for short-term exposure to 300°C (e.g., engine components).
Wear Resistance: Carbide-forming alloy additions (Mo, V) enhance surface hardness, reducing wear from abrasive materials in mining conveyor systems.
Construction Machinery:
Crane load-bearing pins, excavator boom joints, and bulldozer track rollers (ISO 12944 C5-M compliant), withstanding 500,000+ load cycles.
Mining Equipment:
Haul truck axle housings, crusher flywheels, and ore processing components, resisting deformation from 100-ton payloads and abrasive ores.
Industrial Gearboxes:
High-speed gear components, reducer housings, and pinion shafts (ISO 6336 compliant), ensuring minimal backlash and long service life in heavy machinery.
Heavy-Duty Testing
In-house load testing up to 500 tons and fatigue testing (10⁸ cycles), providing detailed reports for safety-critical applications.
Global Compliance
Certified to ISO 6892-1 (metallic materials), EN 10283 (castings), and API 6A (oil & gas components), ensuring use in international heavy equipment projects.
Cost-Effective Strength
30% lower cost than equivalent forged steel parts for large components, achieved through efficient casting and heat treatment processes.
