Premium Custom Stainless Steel Castings Manufacturer in China
Introduction to Stainless Steel Castings
Custom stainless steel castings are precision-engineered components manufactured using high-quality stainless steel alloys through advanced investment casting (lost-wax casting) processes. As a leading stainless steel castings manufacturer in China, we specialize in producing high-performance, corrosion-resistant components for industries ranging from medical and aerospace to automotive and energy.
Our stainless steel investment casting process involves:
- Creating a wax pattern of the desired part
- Coating it with a ceramic shell
- Melting out the wax to form a mold
- Pouring molten stainless steel into the cavity
- Finishing the casting to meet exact specifications
This method ensures exceptional dimensional accuracy, superior surface finish, and complex geometries that are difficult to achieve with other manufacturing techniques.
Why Choose Stainless Steel Castings?
Stainless steel castings offer unmatched durability, corrosion resistance, and mechanical strength, making them ideal for demanding applications. Key advantages include:
✅ Excellent Corrosion Resistance – Withstands harsh chemicals, saltwater, and extreme temperatures.
✅ Superior Surface Finish – Near-net-shape castings reduce the need for extensive machining.
✅ High Dimensional Accuracy – Tight tolerances (±0.005 in) for precision components.
✅ Complex Geometries Possible – Intricate designs with thin walls and fine details.
✅ Wide Material Selection – From 304/316L (food-grade) to 17-4PH (high-strength).
✅ No Burrs or Parting Lines – Smooth finishes ideal for medical and aerospace applications.
Stainless Steel Casting Materials We Offer
We produce castings in various stainless steel grades, each suited for specific applications:
| Material Grade | Properties & Common Uses |
|---|---|
| 304 / 304L | Food-grade steel, excellent corrosion resistance, used in chemical processing, medical devices, and marine components. |
| 316 / 316L | Superior pitting resistance, ideal for marine, pharmaceutical, and high-temperature applications. |
| 410 / 416 | High strength, good machinability, used in bushings, fasteners, and mechanical parts. |
| 17-4PH | Precipitation-hardening steel with exceptional strength, used in aerospace, defense, and high-stress components. |
| Duplex & Super Duplex | Combines austenitic and ferritic properties for extreme corrosion resistance in oil & gas industries. |
