CARBON STEEL FORGING

We offer high-quality carbon steel forging solutions known for their strength, toughness, and cost-effectiveness—ideal for a wide range of industrial applications. Our forged carbon steel components are built to perform under pressure, making them perfect for use in construction, automotive, oil & gas, and heavy machinery industries.

Benefits of Forging Carbon Steel

Carbon steel forging is a widely used manufacturing method due to its versatility, cost-effectiveness, and mechanical strength. At Kannappa Forgings, we deliver high-performance carbon steel forged components tailored for demanding industrial environments. Below are the key benefits:

  • ASTM A105 – 2021 A105
  • ASTM A350 – 2018 LF2
  • ASTM A350 – 2018 LF3
  • SAE 1018
  • SAE 1020
  • SAE 1025
  • AISI/ASTM A29:1038, 1040, 1045
  • AISI 4140

Forged carbon steel offers excellent tensile strength and toughness, making it suitable for parts subjected to heavy loads, impact, and wear. Its dense grain structure ensures reliable performance and long service life.

Carbon steel is more affordable than many alloy or stainless steels, making it a cost-efficient solution for mass production of structural or general-purpose components without compromising strength.

Carbon steel forgings are easy to machine, weld, and process, especially in low and medium carbon grades, allowing for faster production and reduced post-processing time.

The mechanical properties of carbon steel can be tailored through heat treatment processes such as annealing, quenching, and tempering—enabling improved hardness, ductility, and tensile strength for specific applications.

Carbon steel forgings are used across a wide range of industries including construction, automotive, agriculture, oil & gas, and machinery manufacturing—offering flexibility for both standard and high-strength parts.

Carbon steel is 100% recyclable and widely available, making it a sustainable choice for environmentally conscious manufacturing practices.

Carbon Steel Grades

We forge a wide range of carbon steel grades to meet the performance and strength requirements of various industries including construction, automotive, oil & gas, agriculture, and general engineering. Our carbon steel forgings are known for their strength, machinability, and cost-effectiveness.

 

Below are some of the most commonly used carbon steel grades in forging:

2. AISI 1045 (Medium Carbon Steel)

  • Carbon Content: ~0.45%

  • Features: High strength and hardness with good wear resistance.

  • Applications: Gears, axles, crankshafts, bolts, and couplings.

3. AISI 1020

  • Carbon Content: ~0.20%

  • Features: Balanced strength and ductility; easily weldable and machinable.

  • Applications: Forged fittings, base plates, and supports.

4. ASTM A105

  • Carbon Content: Medium (with manganese and other alloying elements)

  • Features: Commonly used in high-pressure systems; excellent mechanical properties.

  • Applications: Flanges, valves, fittings in oil & gas and petrochemical industries.

5. AISI 1035

  • Carbon Content: ~0.35%

  • Features: Stronger than low-carbon grades; good toughness and machinability.

  • Applications: Connecting rods, axles, and levers.

6. AISI 1060 / 1080 (High Carbon Steel)

 

  • Carbon Content: ~0.60% / ~0.80%

  • Features: High hardness and strength after heat treatment.

  • Applications: Springs, wear plates, and cutting tools.
