Minimum hardness of Mild steel is about 140 Vickers hardness.
IS 2062 standard does not specify any Hardness Limit for the material. As such, even the equivalent SA36 does not specify anything on Hardness. But this being a P No.1 material in properties, the commonly accepted Hardness limit is 200HB or 93 HRB. Again there can be variation based on specific application/project requirements.

It is a popular type of steel because it is cheap and its material properties fit into many product applications.Mild steel has a relatively low tensile strength, but it is cheap and malleable and its surface hardness can be increased through carburizing.etc

The Rockwell hardness of welding rods can vary significantly depending on the type of rod and its composition. Generally, mild steel welding rods may have a Rockwell hardness of around 25 to 40 HRC, while stainless steel or high-strength rods can range from 30 to 50 HRC or higher. It's important to consult specific product specifications for precise hardness values, as these can differ based on manufacturing processes and alloying elements.

heating mild steel to 200c
Mild steel is harder than copper as it has a higher hardness level on the Mohs scale. Mild steel is commonly used in construction and manufacturing due to its durability and strength, while copper is known for its excellent electrical conductivity and malleability.

Tool steel typically has a higher carbon content than mild steel. While mild steel generally contains about 0.05% to 0.25% carbon, tool steel can have carbon content ranging from 0.5% to over 1.5%. This increased carbon content in tool steel enhances its hardness and wear resistance, making it suitable for cutting tools and industrial applications, whereas mild steel is more malleable and ductile, making it ideal for structural applications.
mild steel is heavier
