Types of Steel MCQs : This section focuses on the "Types of Steel" in Steel Structures. These Multiple Choice Questions (MCQs) should be practiced to improve the Steel Structures skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
How many main types of steel?
Explanation: The four main types of steel : Carbon Steel, Alloy Steel, Tool Steel and Stainless Steel.
___________ looks dull, matte-like, and is known to be vulnerable to corrosion.
A. Alloy Steel
B. Carbon steel
C. Tool Steel
D. Stainless Steel
Explanation: Carbon steel looks dull, matte-like, and is known to be vulnerable to corrosion.
How many types of Carbon Steel there?
Explanation: Overall, there are three subtypes to this one: low, medium, and high carbon steel, with low containing about .30% of carbon, medium .60%, and high 1.5%.
Alloy steel, which is a mixture of several different metals, like nickel, copper, and aluminum.
C. Can be true or false
D. Can not say
Explanation: True, alloy steel, which is a mixture of several different metals, like nickel, copper, and aluminum.
Stainless steel is shiny and generally has around __________ chromium.
A. 0 to 5%
B. 0 to 15%
C. 10 to 15%
D. 10 to 20%
Explanation: stainless steels are probably the most well-known type on the market. This type is shiny and generally has around 10 to 20% chromium, which is their main alloying element.
Which of the following is the property of high carbon steel?
A. high toughness
B. reduced ductility
C. high strength
D. reduced strength
Explanation: High carbon steel contains high carbon content. Hence it has reduced ductility, toughness and weldability.
High carbon steel is used in ______________
A. transmission lines and microwave towers
B. structural buildings
C. fire resistant buildings
D. for waterproofing
Explanation: High carbon steel is used in transmission lines and microwave towers where relatively light members are joint by bolting.
Fire resistant steels are also called as ____________
A. Stainless steel
B. Weathering steel
C. High strength steel
D. Thermomechanically treated steel
Explanation: Fire resistant steels are also called as thermomechanically treated steel. They perform better than ordinary steel under fire.
What is weathering steel?
A. low-alloy atmospheric corrosion-resistant steel
B. low-carbon steel
C. high strength quenched and tempered steel
D. fire resistant steel
Explanation: Weathering steel are low-alloy atmospheric corrosion-resistant steel. They are often left unpainted. They have an ultimate tensile strength of 480 MPa.
Tool steel is famous for being hard and both heat and scrape resistant.
C. Can be yes or no
D. Can not say
Explanation: Yes, Tool steel is famous for being hard and both heat and scrape resistant.
