Carbon Steel Investment Castings
- Wide material range: Q235, Q345, 20#, 45#, 16Mn, 60Mn, A105 and other grades to match performance needs.
- Complex geometries possible: near-net shapes with fine detail, internal cavities, and thin walls.
- Excellent surface finish: casting roughness as fine as Ra1.6–3.2, reducing polishing requirements.
- Tight dimensional control: dimension tolerance up to CT5–CT6; minimum wall thickness about 0.5 mm.
- Reduced machining cost: accurate investment castings need little secondary machining.
