SAE 1018 is a low carbon steel widely used where good weldability, formability and moderate strength are more important than high hardness. Its low carbon content makes it easy to machine, bend and weld without special precautions.
It is commonly specified for components that will be carburised or case hardened, since the soft core is retained while the surface can be hardened. We supply SAE 1018 bright bar in round, square and hexagonal profiles from our Pune plants.

| Element | Typical Range (%) |
|---|---|
| Carbon (C) | 0.15 – 0.20 |
| Manganese (Mn) | 0.60 – 0.90 |
| Phosphorus (P) | 0.040 max |
| Sulphur (S) | 0.050 max |
| Silicon (Si) | 0.10 max |
Indicative ranges based on published standard specifications. Actual values vary by heat — mill test certificates are supplied with every consignment.
| Property | Typical Value |

Properties depend on size, condition and processing route. Contact us to confirm against your specification.
Produced at our Chakan and Moshi plants, so you buy direct from the manufacturer.
Every consignment is supplied with the mill test certificate for the heat.
Each batch is checked for surface finish and dimensional accuracy before dispatch.

SAE 1018 is a low carbon steel used for general engineering components, shafts, pins, and parts that will be carburised or case hardened. Its low carbon content gives excellent weldability and formability.
They are broadly comparable low carbon grades but come from different standards and the chemistry ranges are not identical. If your drawing specifies one, tell us and we will confirm what we can supply against it.
We manufacture round, square and hexagonal profiles across a range of sizes. Send us your required dimension and quantity and we will confirm availability and lead time.
