Carbon Steel Castings

Carbon steel castings are widely used in industrial manufacturing due to their balance of strength, durability, and cost-efficiency. Produced through the investment casting process, carbon steel investment castings offer reliable mechanical performance while enabling complex geometries and near-net-shape components. These properties make carbon steels a practical material choice for equipment, structural components, and precision mechanical parts across various industries.

Carbon Steel Investment Castings at Aero Metals

Aero Metals produces carbon steel investment casting programs across aerospace, defense, agriculture, and industrial machinery, handling both low- and high-volume production runs. Parts are produced up to 35 lbs, with two on-site spectrometers to verify alloy chemistry at every stage. All castings are manufactured to ISO 9001:2015 standards at our La Porte, Indiana, facility and can be produced to customer-specified requirements or internationally recognized standards, including ASTM.

Characteristics of Carbon Steel Investment Castings

Carbon steel alloys are commonly selected for investment castings because they offer a combination of strength, durability, and cost-effectiveness that suits a wide range of industrial applications.

Key performance characteristics include:

• High strength & Durability
• Hardness & Wear Resistance
• Moderate Machinability
• Cost Efficient

If your part requires enhanced corrosion resistance, stainless steel investment castings offer an alternative.

Carbon Steel Casings for Near-Net-Shape Components

The investment casting process allows carbon steels to be produced as near-net-shape components, reducing material waste and minimizing machining requirements. Aero Metals leverages advanced foundry capabilities and optimized manufacturing processes to efficiently support high-volume production runs, helping customers maintain cost-effective manufacturing without compromising component quality.

Our experience producing carbon-steel investment castings and low-alloy steel investment castings ensures that each part meets strict dimensional and performance requirements.

Carbon Steel Investment Casting Grades

A variety of carbon and alloy steel grades can be used in investment casting, depending on mechanical performance requirements, heat-treatment conditions, and application environments. Aero Metals produces components using multiple carbon and low-alloy steel casting grades, supporting applications where strength, toughness, and durability are essential.

Carbon and Low Alloy Steel Casting Grades

Carbon and low-alloy steels offer strong mechanical performance while remaining cost-effective for industrial components. These materials are commonly used when applications require structural strength, wear resistance, or the ability to withstand mechanical stress.

Typical grades used for carbon steel castings and low alloy steel castings may include:

• 1010
• 1020
• 1035
• 1045
• 4130
• 4140
• 4340
• 8620

These materials are commonly selected for mechanical components that require reliable strength and moderate hardness.

Cast Tool Steel Alloys

For applications requiring higher hardness and improved wear resistance, investment-cast tool steels can be used. These alloys are designed for demanding environments where durability and dimensional stability are critical.

Common tool steel alloys used in casting applications may include:

• A2
• D2, D3, D5 & D7
• H13
• O1
• S5 & S7

Tool steels are typically used in specialized applications where strength and wear resistance must be combined with precise geometry.

Carbon Steel Investment Casting Industries Served
