What is 1035 Carbon Steel?

1035 Carbon Steel is a medium-carbon steel with carbon content ranging from approximately 0.30% to 0.40%. It is classified as a low alloy steel, known for its good balance of strength, toughness, and wear resistance. This grade is generally used when hardness is required without compromising ductility and toughness.

Key Features

• Carbon Content: 0.35% carbon, which makes it suitable for induction and flame hardening.
• Heat Treatment: Can be heat-treated for improved hardness and strength.
• Machinability: Offers good machinability, making it a great choice for manufacturing complex parts that require precision.

Properties of 1035 Carbon Steel

Mechanical Properties

1. Tensile Strength: 1035 Carbon Steel typically has a tensile strength range of around 470 to 700 MPa (megapascals). This makes it suitable for moderately stressed applications but not ideal for extremely high-stress environments.
2. Hardness: It exhibits a Rockwell hardness of approximately 60-65 HRC after proper heat treatment. This makes it hard enough for various machining processes and ideal for creating parts like gears and couplings.
3. Ductility and Toughness: Despite its hardness, 1035 Carbon Steel maintains a good level of ductility, allowing it to withstand shocks or impact loads. This makes it a versatile option for components that may be subject to varying stress conditions.
4. Corrosion Resistance: As a low-alloy steel, it doesn’t have the same level of corrosion resistance as stainless steel, so additional coatings or treatment may be necessary for specific applications.

Physical Properties

• Density: Approximately 7.85 g/cm³, which is typical for carbon steel.
• Melting Point: Around 1,500°C (2,732°F).

Applications of 1035 Carbon Steel

Due to its properties, 1035 Carbon Steel is used in a wide range of applications across various industries. It is particularly favored in manufacturing processes that require forged parts or components subjected to mechanical stresses.

1035 Carbon Steel vs. Other Carbon Steels

When choosing 1035 Carbon Steel for your project, it is important to understand how it compares to other grades of carbon steel. Here’s a brief comparison of 1035 Carbon Steel mit 1018 Carbon Steel and 1045 Carbon Steel, two other commonly used grades.

Eigentum	1035 Carbon Steel	1018 Carbon Steel	1045 Carbon Steel
Carbon Content	0.35%	0.18%	0.45%
Tensile Strength	470 – 700 MPa	440 – 570 MPa	600 – 850 MPa
Hardness	60-65 HRC	50-60 HRC	65-75 HRC
Anwendungen	Gears, shafts, axles	Light-duty machinery	High-stress components
Heat Treatment	Induction, flame hardening	Mild heat treatment	Can be hardened to a higher level

• 1018 Carbon Steel has lower carbon content and is ideal for low-strength applications but doesn’t have the same hardness potential as 1035.
• 1045 Carbon Steel, with higher carbon content, offers greater tensile strength and hardness but is more difficult to machine than 1035.

How to Heat Treat 1035 Carbon Steel

Heat treating is a crucial process that enhances the properties of 1035 Steel, particularly its hardness. Here’s a quick overview of how to heat treat this grade of steel:

1. Austenitizing: Heat the steel to a temperature between 800-850°C (1,472-1,562°F).
2. Quenching: Rapidly cool the steel in water or oil to harden it.
3. Tempering: Reheat to a lower temperature (around 300-400°C or 572-752°F) to reduce brittleness and achieve desired hardness.

This heat treatment process allows 1035 Carbon Steel to become harder, making it suitable for parts like gears, axles, and other components subject to wear and tear.

Abschluss

1035 Carbon Steel is a versatile and cost-effective material that offers a balance of strength, toughness, and machinability. With a carbon content of 0.35%, it is ideal for applications that require moderate strength and hardness, such as gears, axles, and shafts. Its ability to undergo induction and flame hardening makes it an excellent choice for various industrial uses.

By understanding its properties, advantages, and best applications, you can make an informed decision about whether 1035 Carbon Steel is the right material for your project. Whether you’re working in automotive, industrial machinery, or construction, 1035 Carbon Steel offers the right combination of performance and cost-efficiency for many manufacturing needs.
