Engineered for consistent wear performance, our High Wear Resistance Gray Iron Casting Parts leverage the natural abrasion resistance of gray iron’s lamellar graphite structure, delivering reliable service in moderate-wear applications at a competitive cost. Cast from ASTM A48 Grade 40-50 and Grade 60, these parts feature a balanced hardness (HB 190-240) and machinability, ideal for components requiring cost-effective wear resistance in general industrial use.
Gray Iron Advantages
Graphite Structure: 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 wear (e.g., pulley wheels, pump housings).
Grade 60: HB 230-260, ideal for moderate-load applications (e.g., gear teeth, brake drums).
Casting Process Efficiency
Green Sand Molding: High-production process (mold life 500+ cycles) for cost-effective large parts (max weight 2000kg), with dimensional tolerance CT12-13 (ISO 8062).
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: 40-60ksi (276-414MPa), elongation 2-5%, and impact resistance 10-15J, balancing wear and structural integrity.
Environmental Adaptability
Temperature Range: -20°C to 400°C, maintaining 90% hardness at 300°C, suitable for non-critical engine components and industrial gearboxes.
Corrosion Protection: Bitumen coating (100μm) or zinc-rich primer (70μm) for outdoor use, resisting atmospheric corrosion (salt spray 500h, ASTM B117).
General Industrial:
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, loaders), withstanding moderate vibrations and loads.
Gray Iron Specialization
30+ years casting gray iron, with proprietary mold coatings reducing metal penetration and improving surface finish (defect rate ≤1.5%).
Cost Leadership
25% lower cost than equivalent ductile iron parts for non-impact applications, achieved through high-yield green sand casting and efficient sand recycling (90% reuse rate).
Rapid Delivery
10-day lead time for standard grades (Grade 40, 50, 60) 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).
