AE1020 hot rolled steel bar
1.AISI1020 hot rollled steel bar
1020 hot rolled round steel is a circular cross-section steel product made of 1020 carbon structural steel (AISI/SAE standard in the United States, equivalent to China's 20 steel), produced through the hot rolling process. Hot rolling refers to rolling steel billets at high temperatures (typically above the recrystallization temperature) to plastically form them into round steel of specified diameters, featuring high production efficiency and low cost.
2.AISI 1020 hot rolled steel bar Typical applications
Shafts for hydraulic and pneumatic cylinders.
3.AISI 1020 hot rolled steel bar main type and avaliable sizes:
round bars :5mm-130mm
4.AISI 1020 hot rolled steel bar size tolerance
h9,h10,h11 or other tolerance according to client's requirement
5. Chemical Composition (Typical Values)
| Element |
Content (%) |
| Carbon (C) |
0.18-0.23 |
| Manganese (Mn) |
0.30-0.60 |
| Phosphorus (P) |
≤0.040 |
| Sulfur (S) |
≤0.050 |
| Silicon (Si) |
≤0.10 |
It belongs to low-carbon steel, with excellent plasticity and toughness, but lower strength and hardness, and good weldability.

6. Mechanical Properties (Reference Values)
| Property |
Index |
| Tensile Strength (σb) |
≥410 MPa |
| Yield Strength (σs) |
≥245 MPa |
| Elongation (δ5) |
≥25% |
| Reduction of Area (ψ) |
≥55% |
In the hot-rolled state, the microstructure is ferrite + pearlite, and mechanical properties can be further optimized through subsequent heat treatments (such as carburizing and quenching).
7. Steel bar Packing:
*Bars from different heats will not be mixed and dispatched.
*Bars will be bundles and securely metal strapped in 3 min places of the bar length and tagged properly.
*For further processing products such as cold drawn/peeled or heat treated goods, plastics bag wrapped or pallet loading is available according to customer's demands.
8.Delivery time of steel bar:
7-10days of stock,30 days after order confirmed of new material
9.Payment term:TT or LC
10.Free sample:Yes
11.steel bar Inspection: Spectral Tested, Microstructure Tested,Hardness Test,Macrostructure Test,UT test
