Precision Stainless Steel Castings
- Wide material portfolio: Stainless steel (304, 304L, 316, 316L), carbon steel, duplex steel, aluminum, nickel, bronze/brass and other special alloys.
- High dimensional accuracy: Dimension tolerance up to CT5–CT6 with minimum wall thickness down to 0.5 mm.
- Excellent surface quality: Casting roughness Ra3.2–6.4, finished surfaces Ra0.8–1.6, investment casting up to Ra1.6–3.2.
- Tight machining tolerances: Finished machining accuracy can reach ±0.009 mm for critical features.
- Process optimization: Most suitable process and alloy chosen for each part to balance cost, strength, and corrosion resistance.
