Types of Steel Casting Parts
With more than 10 years of forging experience, HDC has provided high-quality forgings to thousands of customers, mainly serving the automotive and motorcycle industries.
Casting Steel Materials
HDC provides comprehensive steel grades for casting. We can also tailor materials for the specific application. Here are some of the most commonly used steel grades.
Available Grades:
- ASTM A27: A27 is a low-carbon steel with a carbon content below 0.25%. Its advantages are lower cost and higher formability, suitable for large components and common universal components like flanges and brackets.
- ASTM A216: A216 can work in a wide temperature range from -29°C to 425°C. In addition to this, it has high compressive strength. These qualities make it ideal for casting high-pressure valves and pump bodies.
- ASTM A352: A352 has excellent toughness at low temperatures (below -46°C), and is widely used in valves, tanks and other components of LNG carriers and cryogenic storage equipment.
Available Grades:
- SUS 304 (ASTM A351 CF8): 304 is a non-magnetic stainless steel. it has excellent corrosion resistance, with good fluidity in the liquid state, making it suitable for casting precision thin-walled castings.
- SUS 316 (ASTM A351 CF8M): 316 adds 2% to 3% molybdenum on the basis of 304, which makes it have better chloride ion corrosion resistance than 304, so it is often used in the marine field.
- SUS 410 (ASTM A743 CA15): 410 is a martensitic stainless steel, which has a lower cost than austenitic stainless steels such as 304,316. It has high strength and can be further improved by heat treatment, making it an ideal material for high-stress castings.
- SUS 2205 (ASTM A890 4A): 2205 is a duplex stainless steel, which is twice as strong as 304, and is suitable for high chloride environments such as seawater and chemical industry.
Available Grades:
- ASTM A217: A217 is a low-alloy steel containing a small amount of chromium and molybdenum, which has the characteristics of high temperature resistance (≤593°C), high pressure, and creep resistance.
- ASTM A297: As a heat-resistant steel, A297 is resistant to oxidation and hot corrosion at extreme high temperatures (≤1150°C), making it suitable for high-temperature scenarios such as industrial furnaces and combustion equipment.

Post Process for Steel Castings
The surface treatment of castings is an indispensable step, and HDC offers you the following commonly used finishing options.
Types of Casting Process
HDC selects the casting process according to customers’ requirements or based on the product characteristics. Below are some commonly used casting processes we can offer:
- Investment Casting (Lost Wax Casting): High precision, good surface quality, but with relatively high upfront costs, suitable for casting extremely complex high value-added parts.
- Die Casting: The highest precision casting method, but the casting strength is not high, is often used in the casting of shells. At the same time, the mold cost is high, and it is more suitable for large-scale production.
- Sand Casting: Low cost, low precision, suitable for all cast steel, commonly used for rough casting of large parts.

Cast steel combines high strength, excellent toughness, and flexible heat treatment capabilities. With a tensile strength of more than 1500 MPa, it is significantly better than cast iron, especially under shock loads or at low temperatures. By adjusting the carbon content and adding alloying elements (such as chromium, nickel, molybdenum), the wear resistance, high temperature resistance or corrosion resistance of the cast steel can be customized to meet different needs.
In the casting process, although steel has a higher melting point and weaker fluidity compared to cast iron, complex or large components can be molded directly by optimizing the gating system design and using computer simulations for defect control. Combined with near-net shape technology, we can significantly reduce processing costs.
In addition, after casting, the properties of steel can be further improved by heat treatment such as quenching and tempering, while cast iron is difficult to achieve the same strength due to the limitation of graphite form. The final steel castings have both high strength and extreme environment resistance, and have become the core manufacturing solution for high-end equipment in energy, transportation, aerospace and other fields.
