Carbon Steel Casting Series 3
JHshukong
Cast from ASTM A27 Grade 55-35-18 and EN-GJL-250, these parts balance tensile strength, machinability, and affordability, ideal for gearboxes, pumps, and structural supports in industrial machinery.
Balanced Mechanical Properties
Strength & Ductility:
Tensile strength 55ksi (379MPa), yield strength 35ksi (241MPa), and elongation 18%, suitable for static and low-vibration loads up to 10 tons.
Hardness HB 170-210, enabling easy machining and welding for on-site modifications.
Alloy Composition: Low-carbon steel (C ≤0.25%) enhances formability and weldability, with optional additions (Mn, Si) for improved hardenability.
Casting Process Efficiency
Green Sand Molding: High-production process for large parts (max weight 2000kg), with dimensional tolerance CT12-13 (ISO 8062) for non-critical features.
As-Cast Surface: Ra ≤25μm, with optional shot blasting (Ra ≤12.5μm) to improve paint adhesion and surface appearance.
Cost-Effective Design
Material Utilization: Optimized wall thickness (5-50mm) and draft angles (5-7°) reduce material waste by 20% compared to precision casting methods.
Standard Sizes Inventory: Over 300 stock part numbers (flanges, brackets, pulleys) for quick delivery, with custom modifications available at minimal cost.
Environmental Adaptability
Temperature Range: -20°C to 400°C, suitable for indoor/outdoor applications without specialized thermal protection.
Corrosion Protection: Optional zinc plating (8μm) or epoxy coating (70μm) for atmospheric corrosion resistance (salt spray 500h, ASTM B117).
Industrial Machinery:
Gearbox housings, motor frames, and conveyor rollers in food processing, resisting wear from non-abrasive materials (e.g., grain, sugar).
Pump & Valve Systems:
Body casings and bonnets for water pumps (ISO 2858 compliant), withstanding pressures up to 10 bar and moderate temperatures.
Material Handling:
Pallet jack forks, trolley wheels, and hoist components, supporting loads up to 5 tons with minimal deformation (deflection ≤L/500).
Cost-Performance Balance
30% lower cost than equivalent alloy steel castings for general applications, achieved through high-yield green sand casting and efficient material sourcing.
Rapid Delivery
10-day lead time for standard grades (Grade 55, 60) and 20-day lead time for custom chemistries, ideal for urgent industrial replacement parts.
Quality Compliance
Certified to ISO 9001:2015 and IATF 16949 (for automotive-adjacent parts), with 85% of raw materials sourced from North American mills.
Design Flexibility
Engineering team provides free DFM reviews, suggesting design modifications to enhance castability and reduce machining requirements.
