Materials & Grades
Steel Casting Materials: Carbon Steel and Alloy Steel
Steel casting material selection should match load, impact, wear, heat treatment, weldability, machining and service environment. Common project discussions may include WCB, WCC, ZG230-450, ZG270-500, ZG35CrMo, ZG42CrMo and high-manganese steel grades, but final feasibility should follow the drawing standard and working conditions.
carbon steel casting
Carbon steel casting is commonly selected for valve bodies, pump housings, frames, brackets, lifting hardware and general machinery parts where strength, weldability and cost control are important.
Typical discussions may include WCB, WCC, ZG200-400, ZG230-450, ZG270-500 and related project standards.
alloy steel casting
Alloy steel casting parts are used when the project needs higher wear resistance, impact strength, toughness, hardness or elevated-temperature performance.
Common discussions may include ZG35CrMo, ZG42CrMo, Mn13 and selected alloy steel routes, depending on heat treatment and inspection requirements.
Material comparison: for corrosion-resistant applications, compare stainless steel casting. For damping and machinability, review iron casting services.
Casting Route
Steel Casting Process Selection for OEM Parts
The right steel casting process depends on part weight, geometry, annual volume, machining allowance, surface expectation, heat treatment and inspection scope. We compare the route before quoting instead of forcing every project into one process.
steel investment casting
Die casting is very similar to permanent mold casting, but instead of gravity, die casting relies on the pressure of the die casting equipment to inject the metal solution into the mold, including: low pressure die casting and high pressure die casting, which allows the material to more fully fill all the details inside the mold. Die casting is very friendly to create castings with complex structures and thin-walled structures, and is widely used in automotive engine housings, electronic equipment brackets, Led lighting accessories, radiator housings, etc.

Engineering Review
Steel Casting Engineering Review Before Tooling
Every custom steel casting project should be reviewed before tooling. This review helps reduce shrinkage risk, hot spots, machining surprises and inspection disputes before molten steel is poured.
Geometry and Castability
We review wall transitions, ribs, bosses, undercuts, draft, fillets, thick-to-thin sections and core structure. The goal is to keep the function while reducing avoidable casting risk.
Machining Allowance
Mark sealing faces, mounting surfaces, datum references, holes, threads and flatness requirements. CNC machining allowance should be planned together with casting route and inspection scope.
Inspection Planning
Critical dimensions, material certificates, hardness, mechanical performance and NDT requirements should be defined before order release, not after shipment.

Heat Treatment Review for Steel Castings
Heat treatment is not an add-on note for steel casting. It affects hardness, strength, toughness, machinability, dimensional stability and final service performance. The heat treatment route should follow material grade and target mechanical properties.
Normalizacja
Used to refine structure and improve machinability for many carbon steel części odlewane.
Quenching + Tempering
Used when hardness, toughness and strength balance must be controlled by grade and service condition.
Stress Relief
Important for parts that need stable dimensions after casting, welding or heavy machining.
Project-Specific Route
Wear-resistant and alloy steel parts may need a different heat treatment route based on the standard and test requirements.
