1020 Steel Plate
1020 Steel Plate
1020 steel, also called mild steel, is a low-carbon steel containing 0.18%–0.23% carbon. It provides good strength, ductility, weldability, and machinability, making it suitable for structural and general-purpose uses. Though not ideal for hardening treatments, it performs well in forming and fabrication.
Zhaojian Steel offers premium 1020 steel in various sizes and thicknesses. It is widely used in automotive parts, mechanical components, construction frames, and stamped metal products. Cost-effective and easy to work with, 1020 mild steel is a dependable choice across multiple industries.

FAQ
Can a 1020 steel plate be cold-rolled or hot-rolled?
Both! 1020 steel plate is available in hot-rolled and cold-rolled forms. Cold-rolled provides tighter tolerances and a smoother finish, while hot-rolled is more cost-effective for structural applications.
How does 1020 compare to 1018 in terms of performance?
Although both are low-carbon steels, 1018 has a slightly better surface finish and dimensional accuracy. However, 1020 provides improved weldability and is more commonly used for forming and general fabrication.
What are the properties of 1020 steel?
1020 steel has a tensile strength of 420 MPa, a yield strength of 350 MPa, and a Brinell hardness of 121. It provides excellent machinability, weldability, and ductility. With a modulus of elasticity of 205 GPa and an elongation of 15%, it is well-suited for forming and general-purpose applications.
