A572 Gr50 is a US standard low alloy high strength structural steel. It has high tensile strength and yield strength, good toughness, good corrosion resistance and good welding performance.

Mild steel plate, also known as low carbon steel plate or simply steel plate, is a type of flat steel product that is made from low carbon steel.

In order to ensure that the hardness of the mild steel plate is appropriate, a surface hardening process is often used to change the surface hardness.

This article will explore the unique properties of these two materials, A36 and 1018 steel, uate their performance in different engineering environments, and how to make wise material selection decisions in specific projects.

Both A36 and 1020 are low-carbon steels that are widely used in construction and manufacturing industries, but there are some differences in their chemical composition and properties.

AISI 1020 Steel is a mild  steel, where "1020" means that the carbon content of this steel is about 0.20%.
