STEEL EXAM PART 1

an alloy with iron and carbon being the primary elements

iron-carbon alloys with greater amounts of carbon

a steel with a major chemical ingredients are iron, carbon, and manganese

less malleable and harder than mild steel.

_______contains carbon as the alloy

Mild steel contains carbon as the alloy, whereas ________ includes chromium.

structural steels with improved atmospheric corrosion resistance

a steel that is extensively used for bridges and has been used externally on some building

_______in plates, bars, and shapes with a thickness of less than 8 in (203 mm) has a minimum yield strength of 36,000 psi (250 MPa) and ultimate tensile strength of 58,000–80,000 psi (400–550 MPa). Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength of 58,000–80,000 psi (400–550 MPa).

list at least 5 advantages of steel as a structural materials(from 1-5 in order)

Iron-Carbon Alloys

Iron-carbon alloys with higher carbon content are less malleable and harder than mild steel.
Alloy with iron and carbon as primary elements.
Steel is a type of iron-carbon alloy that includes manganese as a major chemical ingredient.

Types of Steel

Mild steel contains carbon as the alloy.
Another type of steel includes chromium as an alloying element.

Weathering Steel

A type of structural steel with improved atmospheric corrosion resistance.
Extensively used for bridges and building exteriors.

Mechanical Properties of Weathering Steel

Plates, bars, and shapes with a thickness of less than 8 in (203 mm) have a minimum yield strength of 36,000 psi (250 MPa) and ultimate tensile strength of 58,000–80,000 psi (400–550 MPa).
Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength of 58,000–80,000 psi (400–550 MPa).
