Mild steel, not copper.
Rockwell hardness
Mild steel, typically containing around 0.05% to 0.25% carbon, is known for its ductility, weldability, and ease of machining, making it suitable for general construction and fabrication. C45, on the other hand, is a medium carbon steel with a carbon content of approximately 0.45%, offering higher strength and hardness but lower ductility compared to mild steel. This makes C45 more suitable for applications requiring strength and wear resistance, such as gears and shafts, while mild steel is preferred for structural applications.
Electroplating mild steel enhances its corrosion resistance, extending the lifespan of the metal in various environments. It also improves surface hardness and wear resistance, making it suitable for applications where durability is crucial. Additionally, electroplating can provide aesthetic benefits, allowing for a variety of finishes and colors to be applied. Overall, these advantages make electroplating an effective method for enhancing the performance and appearance of mild steel.
The hardness of St 52 steel is typically around 200-280 BHN (Brinell hardness number).
Minimum hardness of Mild steel is about 140 Vickers hardness.

heating mild steel to 200c
To convert Brinell Hardness Number (BHN) to megapascal (MPa), you can use the conversion factor where 1 BHN is approximately equal to 0.1 MPa. Therefore, to convert BHN to MPa, simply multiply the BHN value by 0.1. For example, a BHN of 400 would be equivalent to 40 MPa.
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 Brinell hardness number (BHN) of aluminum varies depending on the alloy and heat treatment. For example, pure aluminum typically has a BHN of around 15, while some aluminum alloys can have a BHN ranging from 60 to 150. It's important to note that BHN values can differ significantly based on the specific grade and processing of the aluminum.
Ultimate Tensile Strength is the (BHN*500)
You heat your object until its hot red and then you cool it quickly in water
The hardness of steel is incomprehensible. It is very hard.
