Question:
Which of the following is considered as high corrosive resistant material?
Which of the following is considered as high corrosive resistant material?
Show Hint
Stainless steel "stays stainless" because Chromium creates an invisible shield against oxygen and moisture.
Updated On: Jul 4, 2026
- Cast iron
- Stainless steel
- Zinc
- Mild steel
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Corrosion resistance is the ability of a material to resist chemical or electrochemical attack by its environment.
Step 2: Meaning
Alloys are often designed to form protective passive films on their surface to inhibit further oxidation.
Step 3: Analysis
Cast iron and mild steel are highly susceptible to rusting. Zinc is often used as a sacrificial coating because it corrodes easily. Stainless steel contains Chromium, which forms a thin, stable oxide layer that prevents corrosion.
Step 4: Conclusion
Stainless steel is the most corrosion-resistant material among the options provided. Final Answer: (B)
