STAINLESS STEEL CASTING SERVICES
What are Stainless Steel Castings?
Stainless steel castings are stainless steel components cast from iron-based alloys, known for their exceptional corrosion resistance, primarily attributed to a minimum chromium content of 10.5%. Chromium is an element that reacts with oxygen in the air to form a thin, invisible, and self-healing passive layer of chromium oxide on the surface of the steel. This layer acts as a barrier, preventing further corrosion. Additional alloying elements like nickel, molybdenum, and titanium can be added to alter the material’s properties for specific applications, such as increased strength, heat resistance, or improved machinability.
Taiyuan Simis Investment Casting Co., Ltd., a professional investment casting manufacturer of stainless steel castings with a dedicated facility, produces castings widely used in diverse sectors like marine, railway, automotive, energy, pumps and valves, food processing and more, with numerous applications. We use the investment casting technique to produce various grades of stainless steel casting components to achieve complex geometries and intricate details including both internal and external features.
Our Stainless Steel Casting Capabilities
As a leading provider of stainless steel casting services in China, we specialize in high-precision components with dimensional tolerances ranging from CT4 to CT7 and weights up to 100 kg. We combine advanced investment casting process with stringent quality control to achieve these tight tolerances. Our expertise in stainless steel ensures exceptional corrosion resistance, strength, and durability in our castings. We offer both OEM and custom investment casting services for all kinds of stainless steel casting projects.
Advanced Wax Pattern Creation Process
Our wax patterns are created using advanced, automated wax injection machines. This automated process creates high repeatability and efficiency, producing consistent, high-quality wax patterns for every stainless steel casting. The automation also minimizes manual handling and reduces the risk of human error, leading to improved casting quality and faster production times.
In-House Tooling Design and Manufacture
Taiyuan Simis prioritizes client collaboration. Our in-house tooling capabilities enable engineers to work directly with customers, optimizing stainless steel casting designs, which in turn allows the final product to meet their precise specifications and performance requirements, especially for highly customized designs.
Automated Dipping and Coating Process
Beyond the traditional manual shell building process, implementing advanced automated dipping and coating machines allows us to create more complex and robust shell structures for demanding stainless steel castings. These machines allow for precise control over multiple dipping and coating cycles, to achieve optimal shell strength and integrity, even for intricate and challenging casting designs.
Automated Controlled Drying System
Our automated controlled drying system significantly enhances shell-building consistency and efficiency. Precisely controlling temperature, humidity, and airflow, this system ensures uniform drying. Automated shell movement through controlled zones optimizes drying and production capacity. Crucially, this environment prevents shell cracking and defects, directly improving dimensional accuracy, surface finish, and turnaround for stainless steel casting orders.
Our Stainless Steel Expertise
As a professional investment casting manufacturer, our advanced stainless steel investment casting capabilities extend to a wide range of alloys, including all major stainless steel families and numerous grades within each.
- Austenitic Stainless Steels: These are the most widely used stainless steels, known for their excellent corrosion resistance, weldability, and formability. Common grades we cast include 304, 304L, 309, 310, 316, 316L 321 and 347.
- Martensitic Stainless Steels: These offer high hardness, wear resistance, and moderate corrosion resistance. We cast grades such as 410, 414, 416, 420, 431 and 440C for applications requiring high strength and hardness.
- Ferritic Stainless Steels: These are generally less expensive than austenitic grades and offer good corrosion resistance, though not as high. We work with grades such as 409, 430, 430F, 434, 442 and 446.
- Duplex Stainless Steels: Duplex stainless steel castings combine the properties of austenitic and ferritic stainless steels, offering very high strength and excellent corrosion resistance, especially in chloride environments. Common grades include 2205, 2304, 2507 and 2707.
Our Stainless Steel Casting Advantages
Excellent Surface Finish
At Taiyuan Simis, excellent surface finishes are achieved on our stainless steel castings through attention to detail at every stage. This includes using premium, specifically formulated ceramic slurries and waxes for optimal mold creation, employing advanced automated production systems to minimize manual handling and ensure consistent processing, and leveraging the in-depth knowledge of our experienced engineers to carefully control all process parameters.
Overcoming Complex Geometries and Structures
Our manufacturing expertise is useful for producing complex stainless steel castings. We use precision-made ceramic cores for intricate internal structures and employ expertly designed tooling, patterns, and complex gating systems to ensure proper metal flow. We also use optimized pouring techniques and cooling strategies to manage shrinkage, distortion, and residual stress, ensuring structural integrity and dimensional accuracy.
High Production Capacity
Our significant investment in advanced facilities and equipment has resulted in a high production capacity, enabling us to produce over 2000 tons of stainless steel castings annually. This staggering capacity allows us to accommodate both large-volume orders and smaller, specialized projects, while maintaining consistent quality and on-time delivery.
