The Steel Quiz
(310).jpg "The Steel Quiz - Quiz")
From cars to paper clips, from sky scrapers to your screw driver, steel is the building block of many items that account for modern society. How much do you know about steel, or the differences between iron steel, aluminum and other common metals.
- 1.
The ingredient that makes stainless steel “stainless” is:
- A.
Zinc
- B.
Carbon
- C.
Aluminum
- D.
Chromium
Correct Answer
D. ChromiumExplanation
Chromium is the ingredient that makes stainless steel "stainless". It forms a protective layer on the surface of the steel, preventing it from rusting or corroding. This layer is composed of chromium oxide, which is highly resistant to oxidation and corrosion. Therefore, the presence of chromium in stainless steel enhances its durability and makes it suitable for various applications where resistance to corrosion is important.Rate this question:

A main difference between Pig iron and steel is that steel has a lower level of...
- A.
Copper
- B.
Oxygen
- C.
Carbon
- D.
Aluminum
Correct Answer
C. CarbonExplanation
Pig iron and steel are both iron alloys, but the main difference between them is the carbon content. Pig iron has a higher carbon content, typically around 3-4%, while steel has a lower carbon content, usually less than 2%. This difference in carbon levels affects the properties and characteristics of the materials. Steel with lower carbon content is stronger, more malleable, and has better weldability compared to pig iron. Therefore, the correct answer is carbon.Rate this question:

What does PCI stand for in a blast furnace operation?
- A.
Pulverized Coal Injection
- B.
Piped Coke Injection
- C.
Pulverized Coke Infusion
- D.
Piped Coal Infusion
Correct Answer
A. Pulverized Coal InjectionExplanation
PCI stands for Pulverized Coal Injection in a blast furnace operation. This process involves injecting pulverized coal into the blast furnace to replace some of the coke traditionally used as fuel. The pulverized coal is blown into the furnace through tuyeres, where it reacts with the hot air and helps in the reduction of iron ore to produce molten iron. PCI is a widely used technique in modern blast furnace operations as it allows for the reduction of coke consumption and improves the overall efficiency of the process.Rate this question:

Galvanized Steel is coated with ___ to protect the steel from corrosion.
- A.
Chromium
- B.
Zinc
- C.
Tin
- D.
Aluminum
Correct Answer
B. ZincExplanation
Galvanized steel is coated with zinc to protect it from corrosion. Zinc acts as a sacrificial anode, meaning it corrodes before the steel does. This sacrificial corrosion process prevents the steel from rusting. Zinc is widely used for this purpose due to its excellent corrosion resistance properties. It forms a protective layer on the steel surface, preventing moisture and other corrosive elements from reaching the steel.Rate this question:

What is the melting point of low carbon steel?
- A.
961°C (1762°F)
- B.
1063°C (1946°F)
- C.
1464°C (2700°F)
- D.
3600°C (6512°F)
Correct Answer
C. 1464°C (2700°F)Explanation
961°C = Silver. 1063°C = Gold. 3600°C = Carbon.Rate this question:
