When producing gray cast iron, we adhere strictly to the chemical composition and mechanical property requirements provided by our customers. We also have advanced equipment to detect any casting defects within the gray iron sand castings.

Ferrous alloys with carbon content exceeding 2% are known as cast irons. Although cast irons can have a carbon percentage ranging from 2 to 6.67%, practically it is usually between 2 and 4% due to their excellent casting qualities.

Gray iron is a cost-effective material compared to ductile iron, but it has lower tensile strength and ductility. While gray iron cannot replace carbon steel, ductile iron, with its higher tensile strength, yield strength, and elongation, can substitute carbon steel in certain applications.

An Overview of Cast Iron Castings

Cast iron castings have a rich history in the metalworking industry, serving various applications. These castings are found in products ranging from urban infrastructure to kitchen accessories, illustrating their broad utility.

Understanding Cast Iron Castings

Cast Iron Definition and Types:

Cast iron is an iron-carbon alloy produced by smelting the material and pouring it into molds. The primary components are iron, carbon, silicon, and small amounts of other elements like phosphorus, sulfur, and manganese. The types of cast iron include grey cast iron, ductile cast iron, white cast iron, and malleable cast iron, each varying by their unique compositions and properties.

Key Properties:

• Grey Iron: Known for good machinability, thermal conductivity, and high compressive strength.
• Ductile Iron: Characterized by high ductility and strength.
• White Iron: Noted for its high compressive strength and hardness.
• Malleable Iron: Possesses high ductility and excellent machining capabilities.

Factors Influencing Cast Iron Properties:

Chemical Composition:

• Carbon: Higher carbon content decreases ductility and thermal conductivity.
• Silicon: Enhances graphitization and increases resistance to abrasion and corrosion.
• Manganese: Promotes the formation of white iron and increases abrasion resistance.
• Phosphorus: Increases fluidity but can cause brittleness.
• Sulfur: Reduces castability and ductility.

Cooling Rate:

The cooling rate significantly influences the crystal structure of cast iron. Faster cooling produces white iron, while slower cooling results in grey iron. The type of casting pattern and casting thickness also affect the cooling rate.

RMC Sand Casting Capabilities

RMC utilizes various casting processes, including green sand mold casting, pre-coated resin sand casting, and no-bake mold casting. Our facility can handle gray and ductile iron castings up to 10 tons and steel castings up to 5 tons. We manufacture parts in diverse materials such as stainless steel, carbon steel, wear-resistant steel, and heat-resistant steel.

Our state-of-the-art facilities and experienced team enable us to create intricate and high-quality sand castings. We offer both machine and manual molding and can handle low to high-volume orders. Our inspection services include spectrographic analysis, hardness testing, mechanical property analysis, impact testing, and various types of cleanliness inspections.

Why Cast Iron Castings are Popular?

Cast iron is favored for its excellent castability, good fluidity, low melting point, and durability. It is ideal for producing outdoor furniture, marine parts, and kitchen accessories due to its resistance to wear and environmental elements.

Disadvantages of Cast Iron Castings

Despite many advantages, cast iron products are generally brittle, which limits their use in applications requiring high impact resistance. Additionally, white cast iron is non-machinable, and ductile and malleable cast irons are more expensive than gray cast iron.
