What is Acero al carbono 1045?
Understanding 1045 Carbon Steel Composition
1045 carbon steel is often referred to as “medium carbon steel” because of its carbon content, which typically falls in the range of 0.43% to 0.50%. This makes it a stronger alternative to lower-carbon steels, which are easier to form and weld but don’t provide the same strength. The higher carbon content in 1045 improves its hardness, tensile strength, and wear resistance, making it an excellent choice for components that need to withstand high levels of stress and mechanical forces.
Here is a breakdown of the typical composition of 1045 carbon steel:
- Carbono (C): 0.43% – 0.50%
- Manganeso (Mn): 0.60% – 0.90%
- Fósforo (P): 0.04% max
- Azufre (S): 0.05% max
- Hierro (Fe): Balance
This composition provides a balanced combination of strength, toughness, and resistance to wear. Additionally, 1045 carbon steel is relatively easy to machine compared to higher carbon steels, which makes it suitable for various manufacturing processes, including precision casting and CNC machining.
Why Choose 1045 Carbon Steel for Your Components?
- Durability and Strength: With its balanced carbon content, 1045 offers excellent tensile strength, ranging from 570 to 700 MPa, which ensures the durability of the components.
- Maquinabilidad: Unlike higher-carbon steels, 1045 carbon steel provides a good level of machinability, which is essential in precision casting and CNC machining processes.
- Hardening Capabilities: It responds well to heat treatment processes, such as induction hardening, which increases surface hardness while maintaining core toughness.
- Costo-efectividad: While offering great mechanical properties, 1045 is more affordable compared to high-alloy steels, making it a cost-effective option for medium-strength applications.
En Leierwo, we specialize in precision casting and CNC machining for custom parts made from 1045 carbon steel, tailored to meet the unique needs of our clients. Our experience and expertise allow us to provide high-quality solutions with an emphasis on strength, durability, and performance.
Key Applications of 1045 Carbon Steel

Common Uses in Manufacturing and Industry
1045 carbon steel is a versatile material used in a wide range of applications that require moderate strength, toughness, and wear resistance. Some of the most common applications include:
- Shafts: Used in machinery and heavy equipment, shafts made from 1045 are strong enough to handle torsional stresses while maintaining ductility.
- Gears and Crankshafts: The ability to undergo heat treatment allows 1045 steel to be used in the production of gears and crankshafts for internal combustion engines.
- Hydraulic and Pneumatic Cylinder Rods: In hydraulic and pneumatic systems, 1045 carbon steel’s wear resistance and strength are essential in ensuring the longevity of cylinder rods.
- Componentes automotrices: Parts such as axles, rods, and bearing housings, which are subjected to high stress, are often made from 1045 carbon steel due to its excellent strength and machinability.
- Industrial Tools: 1045 carbon steel is used for producing tools like spindles, valve bodies, and other machinery components where strength and durability are necessary.
En Leierwo, we offer a wide range of customized solutions for parts made from 1045 carbon steel. Our engineers work closely with you to design and produce the best components that meet your specific needs, while our precision casting and machining services ensure the highest quality at every stage of production.
The Benefits of 1045 Carbon Steel in Precision Casting
Superior Toughness and Hardness
One of the primary benefits of 1045 carbon steel is its toughness. The material’s hardness can reach HB 170 to 250, making it suitable for applications that require resistance to wear, impact, and stress. When subjected to heat treatment, such as induction hardening, it can achieve a significant increase in surface hardness, which is ideal for parts that need to withstand abrasive environments.
Excellent Weldability and Formability
1045 carbon steel has a moderate carbon content, which makes it more suitable for welding than higher-carbon steels. This property is essential for the casting process, especially when parts need to be assembled after casting. Its formability also ensures that it can be cast into intricate shapes without compromising structural integrity.
High Response to Heat Treatment
Due to its medium carbon content, the carbon steel responds exceptionally well to heat treatments such as normalizing, annealing, and hardening. These processes increase the hardness and strength of the material, making it well-suited for parts like gears, shafts, and other components that must endure high stress and wear.
