Gray Iron Casting Series 1
JHshukong
Designed for broad industrial use, our General-Purpose Wear-Resistant Gray Iron Casting Series 1 offers cost-effective solutions for moderate-wear applications, leveraging the natural abrasion resistance of gray iron’s lamellar graphite structure.
Gray Iron Advantages
Graphite Structure Benefits: Flake graphite acts as a solid lubricant, reducing friction coefficient to 0.2-0.3 (ASTM D1894), minimizing wear in dry or lightly lubricated environments.
Grade Options:
Grade 40 (HB 180-210): Suitable for low-load applications (e.g., pulley wheels, motor bases).
Grade 50 (HB 210-240): Ideal for moderate loads (e.g., gear teeth, pump housings).
Casting Process Efficiency
Green Sand Molding: High-production process (mold life 500+ cycles) for large parts (max weight 2000kg), with dimensional tolerance CT12-13 (ISO 8062) for non-critical features.
As-Cast Surface: Ra ≤25μm, with optional machining to Ra ≤6.3μm for mating surfaces, reducing post-casting processing time by 30%.
Mechanical Consistency
Tensile Strength: 40-50ksi (276-345MPa), elongation 2-3%, and impact resistance 10-15J, providing reliable performance in static and low-vibration scenarios.
Heat Treatment: Optional annealing to eliminate internal stress, improving dimensional stability for precision-critical components.
Cost-Effective Design
Material Efficiency: Optimized wall thickness (5-50mm) and minimal draft angles (5-7°) reduce material waste by 20% compared to precision casting methods.
Standard Sizes Inventory: Over 300 common part numbers in stock (e.g., flanges, brackets, pulleys), enabling same-day shipping for urgent orders.
General Machinery:
Gearboxes, motor frames, and conveyor rollers in food processing, resisting wear from grain, sugar, and other non-abrasive materials.
Automotive Aftermarket:
Brake drums, clutch housings, and differential cases (SAE J431 compliant), offering OEM-quality at 20% lower cost than forged alternatives.
Construction Equipment:
Pump casings and transmission components in compact machinery (e.g., mini-excavators), withstanding moderate vibrations and loads.
Gray Iron Specialization
30+ years of expertise, with proprietary mold coatings reducing metal penetration and improving surface finish (defect rate ≤1.5%, industry leading).
Cost Leadership
25% lower cost than equivalent ductile iron parts for non-impact applications, achieved through high-yield green sand casting and 90% sand recycling rate.
Rapid Delivery
10-day lead time for standard grades (Grade 40, 50) and 20-day lead time for custom chemistries (e.g., high-silicon gray iron for heat resistance).
Quality Compliance
Certified to ISO 9001:2015 and IATF 16949 (for automotive parts), with 85% of raw materials sourced from North American mills (AISI, ASTM compliant).
