Specification & Technical Highlights |
Customer Benefits / Value |
| Material |
Grade 310 Stainless Steel (High-Ni-Cr Heat-Resistant Steel) |
Delivers ultimate scaling resistance and high creep strength under continuous high temperatures up to 1100°C+; prevents thermal fatigue. |
| Application Scenario |
Automotive Field / Advanced Turbocharging, EGR, & Exhaust System Components |
Specifically engineered for high-vibration and aggressive hot gas routing in high-performance or heavy-duty automotive engines. |
| Unit Weight |
7.88 kg |
Robust yet structurally optimized weight, presenting ideal thickness consistency for critical automotive assemblies. |
| Geometry Feature |
Long Special-Shaped Through-Hole & Narrow Grooves |
Intricate geometric layout; seamlessly routes internal fluids or exhaust gases while saving outer layout space. |
| Core Technology |
Water-Soluble Core Molding for intricate inner hole |
Creates a flawless, seamless internal cavity for the complex long-through profile, eliminating air flow restriction and minimizing engine backpressure. |
| Pouring System |
Multi-Gate Gating System Molding |
Scientifically engineered gating layout ensures uniform steel liquid distribution, completely avoiding cold shuts or porosity in narrow groove regions. |
| Casting Tolerance |
ISO 8062 (GB/T6414) CT6 Grade
|
High near-net-shape accuracy simplifies final CNC machining setup on critical joint faces and bolt holes. |
Strict Automotive-Grade Quality Control & Testing
To ensure fail-safe performance and precise dimensional compliance under repetitive thermal shock cycles, every single batch undergoes elite validation:
-
Internal Channel Clearance Inspection: 100% video-endoscope verified to ensure that the long special-shaped through-holes and narrow grooves are completely smooth, with absolutely zero water-soluble core residues or internal slag inclusions.
-
Dimensional Accuracy & True Position (CMM): Measured via high-precision Coordinate Measuring Machines to check the geometric layout profile of the long part, preventing structural warping and guaranteeing flawless alignment with mating automotive housings.
-
High-Temperature Metallurgy Control: Validated by Spectrometers to ensure exact 310 grade chemical composition (25% Chromium, 20% Nickel) for maximum oxidation resistance.
-
Non-Destructive Testing (NDT): Processed via Liquid Penetrant Testing (LPT) to guarantee that the critical narrow grooves and thin-wall radiuses are completely free of surface or thermal micro-cracks.
