When it comes to selecting carbon steel pipes for industrial and mechanical applications, AISI 1018/1020 Pipes are among the most preferred choices due to their excellent mechanical properties, weldability, and affordability. These low-carbon steel grades are widely used in structural, automotive, and general engineering sectors.
In this blog, we’ll take a closer look at AISI 1018/1020 Pipes, their features, key differences, and how they impact your project decisions. We’ll also explore aspects like sae 1018 steel price and a comparison between sae 1018 vs 1020 steel to help you make an informed choice.
What Are AISI 1018/1020 Pipes?
AISI 1018 Pipes are made from a low-carbon steel alloy with approximately 0.18% carbon content, while AISI 1020 Pipes contain about 0.20% carbon. Both are part of the SAE-AISI classification system and are classified as mild steels. These pipes are known for their:
Excellent machinability
High surface finish
Good weldability and formability
Uniform mechanical properties
They are used for applications such as shafts, pins, fasteners, gears, machinery parts, and many general-purpose components.
Mechanical and Chemical Properties

|---|---|---|
| Carbon Content (%) | 0.15 – 0.20 | 0.18 – 0.23 |
| Yield Strength (MPa) | Approx. 370 | Approx. 350 |
| Tensile Strength (MPa) | Approx. 440 | Approx. 420 |
| Elongation (%) | 15 – 20 | 15 – 30 |
| Hardness (Brinell) | ~126 | ~119 |
Common Applications
AISI 1018/1020 Pipes are commonly used in:
Machinery components
Auto parts and shafts
Oil and gas industry
Agriculture equipment
Structural frameworks
These pipes perform well under moderate loads and pressures, making them reliable for light- to medium-duty operations.
Sae 1018 vs 1020 Steel: Key Differences
When evaluating sae 1018 vs 1020 steel, the differences may seem small, but they can be significant depending on the application:
Carbon Content:
SAE 1020 has slightly higher carbon content, offering slightly better strength but lower ductility compared to SAE 1018.Machinability:
Both grades are easy to machine, but SAE 1018 has better machinability due to its lower carbon and higher manganese content.Weldability:
Both steels offer excellent weldability, though SAE 1018 has a slight edge in ease of welding.Cost Considerations:
Due to minor differences in processing, availability, and use, the sae 1018 steel price may vary slightly from 1020, though both remain cost-effective.
Sae 1018 Steel Price
The sae 1018 steel price can fluctuate based on market demand, supplier location, and order volume. As of the latest market trends:
SAE 1018 pipes are generally priced between ₹55 to ₹75 per kg in India.
Prices can vary depending on form (round, square, seamless), finish (cold drawn or hot rolled), and other specifications.
Always contact verified suppliers or distributors for the most accurate and bulk pricing options.
Why Choose AISI 1018/1020 Pipes?
Here are some top reasons why industries choose AISI 1018/1020 Pipes:
Affordable Material Cost: Both grades are cost-efficient for medium-duty applications.
Ease of Fabrication: Excellent for cutting, forming, drilling, and welding.
Versatility: Suitable for a wide range of applications, from automotive to structural use.
