Different Materials of Steel Castings
1. Carbon steel
Carbon steel casting is the direct production of steel castings through methods such as investment casting and shell casting. Carbon steel offers excellent casting properties, high strength, and excellent ductility and toughness. Cast carbon steel overcomes the shortcomings of cast iron in terms of ductility and toughness, offering excellent overall performance comparable to forged steel while maintaining the flexibility to form complex structures. It is suitable for manufacturing critical components with complex shapes and subject to heavy or impact loads.
· Excellent Castability: Moderate fluidity and high shrinkage (requiring appropriate riser and chill design) enable the production of complex castings.
· Excellent Overall Mechanical Properties: Combining high strength and hardness with ductility and impact toughness far exceeding that of cast iron, it can withstand impact and fatigue loads.
· Excellent Weldability: Medium and low carbon cast steels, in particular, exhibit excellent weldability, facilitating repair and assembly welding of castings.
· Heat Treatable: Heat treatment processes such as annealing, normalizing, and quenching and tempering can eliminate casting stresses, refine grains, and significantly improve mechanical properties.

2. Alloy steel
Alloy steel casting involves adding significant amounts of alloying elements (such as nickel, chromium, molybdenum, and manganese) to carbon steel to enhance the mechanical properties, hardenability, and performance under severe service conditions. Compared to carbon steel, alloy steels offer greater strength, toughness, and wear resistance and can be tailored through heat treatment to specific applications such as high stress, wear, or high temperatures. The combination of specific alloying elements and customized heat treatment processes enables foundries to design materials with precise performance characteristics to meet the most demanding applications in the energy, mining, and heavy industries.
· Enhanced Mechanical Properties: The addition of alloying elements significantly increases tensile strength, yield strength, and impact toughness, especially in larger cross-sections.
· Excellent Hardenability: Alloying elements (particularly Cr, Mo, Ni) allow for deeper and more uniform hardening during heat treatment, enabling the production of high-strength heavy-section castings.

Stainless steel can be directly produced into corrosion- and heat-resistant components through investment casting, shell casting, and lost foam casting. It is an ideal choice for manufacturing critical components that must withstand harsh environments, high temperatures, or require high purity and complex geometries.
