Our Expertise in Carbon Steel Casting Parts

We specialize in engineering-grade carbon steel casting components designed for load-bearing, impact-resistant, and cost-efficient industrial applications. Our manufacturing capability covers thin-wall sections, complex internal runners, and heavy-duty geometries required for harsh mechanical environments.

Using precision investment casting, sand casting, and controlled pouring & solidification simulation, we produce custom carbon steel assemblies for automotive, construction hardware, mining equipment, lifting devices, agricultural machinery, and energy-sector components.

Our size capability ranges from 0.1 to 24 inches, with part weights from 1 ounce to 50 pounds, supporting both prototype and stable mass-production batches. Every casting undergoes mechanical-property verification to ensure required strength, toughness, fatigue resistance, and dimensional consistency based on final operating conditions.

Our Manufacturing Approach

To ensure consistent casting quality, we've broken down “control” into tangible data and processes: material batch traceability, comprehensive casting parameter logging, pre-production simulation validation, and digital verification for every batch inspection—replacing reliance on master craftsmen's intuition.

Alloy Composition and Melting Control

We apply spectral analysis and in-furnace composition adjustments for carbon and alloy steels, such as AISI 1020, 1045, 4130, 4140, and 8620, as well as ASTM A216 WCB. Focus points include C, Mn, Si, S, P, Cr, Mo, Ni precision control to achieve target strength, hardenability, and weldability, while preventing porosity, segregation, and grain coarsening.

Engineering Design of Mold & Feeding Systems

Mold engineering is optimized using flow and solidification simulation to control shrinkage, hot spots, crack-risk zones, and inclusion trapping.

Gate, riser, and chill placements are designed based on thermal gradient, modulus ratio, and stress-bearing areas to ensure structural reliability under real-world loads.

Heat Treatment for Mechanical Performance

Heat-treatment processes vary based on grade and performance requirements, including:

Normalizing → grain refinement/stress balance. Quenching + Tempering → high strength & toughness. Carburizing & Case Hardening (for 8620 / 20Cr)Typical results achieve optimized yield strength, impact toughness (Charpy), fatigue resistance, and dimensional stability, depending on the service conditions.

Precision Machining & Quality Inspection

CNC finishing achieves dimensional accuracy of ±0.05–0.1 mm with CMM verification for complex tolerances. The surface finish typically reaches a Ra of 3.2–6.3 μm, depending on the casting and machining stages. Complete inspection options are available, including UT, MT, tensile, hardness, metallography, run-out, thread gauge validation, and alignment with engineering drawings and acceptance standards.

What are the Advantages of Carbon Steel Casting Parts ?

  • High Strength-to-Cost Ratio Carbon steel provides excellent mechanical strength and impact resistance at a significantly lower cost than stainless steel, alloy steel, or forging-only solutions.
  • Wide Heat-Treatment Flexibility Properties can be customized through normalizing, quenching + tempering, or case hardening, enabling tailored performance for different stress, wear, or fatigue conditions.
  • Better Weldability and Repairability Compared to high-alloy materials, carbon steel castings can be readily welded, modified, or repaired on-site, reducing lifecycle costs and downtime risks.
  • Suitable for Heavy-Duty and Structural Parts Ideal for load-bearing, shock-absorbing, and large-section components used in machinery frames, mining equipment, lifting hardware, automotive, and construction parts.

Suppose you're unsure whether carbon steel is the right material. In that case, we help evaluate stress-load conditions, cost trade-offs, heat-treatment feasibility, and fatigue life through early-stage manufacturability assessments and process simulations.
