Our Steel Casting Process
We use a range of steel casting routes to match different part sizes and requirements.
Investment casting, sand casting, and centrifugal casting are our core processes, supported by shell molding, core making, heat treatment, and finish machining as needed.
Steel Investment Casting (Lost Wax)
Precision steel investment casting enables intricate shapes with tight tolerances and smooth surface finish, ideal for complex pump, valve, and machinery components.
It supports alloy steels and stainless grades such as CF8M, CF3M, 17-4PH, and heat-resistant tool steels.
Steel Sand Casting
Steel sand casting allows large and heavy-duty industrial components with reliable mechanical strength.
Common grades include WCB, LCB for pressure parts, and WC6 for high-temperature steam service.
Centrifugal Casting for Steel Parts
Centrifugal steel casting produces highly dense, defect-free ring-shaped parts with superior wear and pressure resistance.
Typical materials include high-alloy and stainless steels for pump sleeves, bearing rings, and turbine components.
Common Steel Casting Alloys
We cast carbon steel, low-temperature steel, alloy steel, and stainless steel for critical industrial use. These materials are selected for pressure-retaining components, corrosion-resistant parts, and high-temperature service in valves, pumps, turbines, and pipeline systems.
The grades below represent widely used steels that offer a reliable balance of strength, impact resistance, weldability, and corrosion performance for demanding applications.
| Steel Grade | Key Properties | Typical Applications | Example Parts |
|---|---|---|---|
| ASTM A216 WCB | Carbon steel casting for high-temperature service with good strength and toughness after normalizing and tempering. Good weldability for general-purpose pressure components. | Valve and pump bodies, flanges and fittings in oil & gas, power generation and industrial piping systems. | Gate Valve Body, Pump Casing, Pipe Flange |
| ASTM A352 LCB | Low-temperature carbon steel casting with strong notch toughness down to −46 °C. Retains impact resistance in cryogenic and cold environments. | Low-temperature valves and pumps, LNG equipment, refrigeration and cold-climate piping components. | Cryogenic Valve Body, LNG Pump Housing, LT Flange |
| ASTM A217 WC6 | Cr-Mo low-alloy steel casting with high strength and creep resistance at elevated temperature. Excellent thermal fatigue resistance for long-term pressure service. | Steam valves, boiler parts and turbine components in power and petrochemical applications. | Steam Valve Body, Stop Valve Bonnet, Turbine Casing |
| ASTM A351 CF8M | Austenitic stainless casting equivalent to 316 with excellent corrosion resistance and weldability. Suitable for chemical, food and marine environments. | Corrosion-resistant valves, pumps, sanitary equipment and marine hardware. | Stainless Valve Body, Pump Impeller, Sanitary Fitting |
| ASTM A351 CF3M | Low-carbon 316 stainless casting grade with superior weld corrosion resistance and low sensitization risk. Ideal for welded components in corrosive service. | Welded piping components, corrosion-resistant tanks and pressure parts requiring reliable weld performance. | Welded Valve Body, Pump Casing, Piping Spool |
FAQ – Frequently Asked Questions
Steel casting is the process of pouring molten steel into molds to create complex components. It offers excellent strength and toughness for critical industrial applications.
Common materials include carbon steel, alloy steel, and stainless steel. The selection depends on the application’s requirements for strength, wear resistance, or corrosion resistance.
