You heat your object until its hot red and then you cool it quickly in water
Minimum hardness of Mild steel is about 140 Vickers hardness.
it is 90
Usually steel, alloyed with vanadium(to increase springiness) and chromium(to increase hardness and resistance to wear)
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
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.

The Brinell hardness number (BHN) of mild steel typically ranges from about 120 to 180 HB, depending on its composition and treatment. Mild steel, being a low-carbon steel, exhibits relatively low hardness compared to harder steels or alloys. The precise BHN can vary based on factors such as the specific grade of mild steel and its manufacturing process.
200 bhn max.

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.
The hardness of stainless steel varies with the alloy and the finish treatment(s). There are hundreds of different stainless steels, and they come in a range of hardness. In addition, there are many ways to treat steel (stainless or otherwise) to increase (or even decrease) its hardness.

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 cannot be hardened significantly because it has a low carbon content, typically around 0.05% to 0.25%. This low carbon level limits its ability to form the hard microstructure known as martensite during heat treatment processes. Instead, mild steel primarily retains a softer ferrite-pearlite structure, which provides ductility but not hardness. Consequently, while mild steel can be surface-hardened through processes like carburizing, its overall hardness remains limited compared to higher carbon steels.
The hardness of steel is incomprehensible. It is very hard.
