What defines a ferrous metal?
It contains iron as its primary element.
What are the three main types of ferrous metals?
Cast iron, wrought iron, and steel.
What is cast iron’s main property?
High compressive strength but brittleness.
What makes wrought iron malleable?
Its low carbon content.
What is stainless steel?
Steel with added chromium for corrosion resistance.
What is the Bessemer process?
A method to remove impurities from iron by blowing air through molten metal.
Why is high-carbon steel harder than low-carbon steel?
Higher carbon increases hardness but reduces ductility.
What is ductility?
The ability of a metal to stretch without breaking.
What is a blast furnace used for?
Extracting iron from ore.
What is annealing?
Heating and cooling metal to make it softer.
What is the main use of wrought iron?
Decorative gates and fences.
What is the purpose of rebar in construction?
To reinforce concrete.
What is galvanization?
Coating steel with zinc to prevent rust.
What is tensile strength?
The maximum stress a material can withstand before breaking.
What is the elastic region in a stress-strain curve?
Where material deforms but returns to its original shape.
What is the plastic region?
Where material deformation becomes permanent.
What is the role of chromium in stainless steel?
It forms a protective oxide layer to prevent rust.
What are some applications of ferrous metals in construction?
Steel beams, bridges, and pipelines.
What is the primary disadvantage of ferrous metals?
They are prone to rusting (except stainless steel).
What is quenching?
Rapidly cooling metal to harden it.
What is tempering?
Heating quenched metal to reduce brittleness.
What is the difference between hot-rolled and cold-rolled steel?
Hot-rolled is shaped at high temperatures; cold-rolled is finished at room temperature for precision.
What is slag?
A byproduct of impurities removed during iron production.
What is a stress-strain curve used for?
To analyze a material's mechanical properties.
What is a tensile test?
A method to measure a material's strength under tension.
What is the purpose of carbon in steel?
To increase hardness and strength.
What is pig iron?
A crude form of iron with high carbon content, used as a precursor for steel.
What is wrought iron’s key advantage?
Its corrosion resistance.
What is the ultimate tensile strength (UTS)?
The maximum stress a material can endure before failure.
Why is ferrous metal recycling important?
It conserves resources and reduces environmental impact.
