yes
yes of course
Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
Typically mild steel can withstand vibration better because it has a higher density than the more brittle cast iron but cast iron may be better at absorbing vibrations than mild steel, due to its lower density.
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
yes mild steel comes in strips rather than blocks
Many stainless steels are stronger than mild steel. Stainless steel is also corrosion resistant to many different environments where mild steel is not.
Lead has a higher density than steel.
High tensile steel is strong steel. It is 10 times stronger than wood and more than twice the tensile strength of mild steel. High tensile steel is commonly used in highway guardrails.
"Mild steel" is low-carbon steel. It is the cheapest, most common and and most versatile form of steel, and is more malleable than high-carbon steels. It would be used in door handles because it is cheap and easily shaped.
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.
