carbon
Pure iron is too soft for many uses. Different metals are added in order to strengthen the steel and make it harder.
The steel rods are there to strengthen the concrete - making it reinforced concrete.
aliuminum
why are other metals added to stainless steel
The body is made fibreglass, with a full steel chassis, and steel framework or 'birdcage' to strengthen the body.
Steel with chroniuum added
There is no 'steel' unless added by a mod.
Almost Anything! Used in construction to strengthen foundations used to make cars (mild steel) used in almost every product :D
It is a steel making stage in whice steel refined and different elements are added in it.
Most steel bumpers are chromium plated for the shiny exterior look and to prevent the rusting (corrosion) of the underlying steel (iron). It is not "added" to the steel, but electroplated onto the surface.
Structures can be strengthened using materials such as steel reinforcements, carbon fiber, or reinforced concrete. These materials are added to improve the strength, durability, and load-bearing capacity of the structure. Additionally, techniques like increasing wall thickness, adding bracing elements, or using high-strength materials can also be employed to strengthen structures.
