Nickel steel, known for its high tensile strength and elasticity, is composed of which two primary elements?
- 1Iron and Chromium
- 2Iron and Nickel✓
- 3Nickel and Aluminum
- 4Nickel and Copper
Correct answer
Iron and Nickel
Explanation
स्पष्टीकरण:
निकल स्टील (Nickel Steel) एक मजबूत मिश्र धातु है जो मुख्य रूप से आयरन (लोहा) और निकेल से मिलकर बनी होती है। इसमें लोहे के साथ लगभग 2% से 5% (या उससे अधिक) निकेल मिलाया जाता है।
मुख्य बिंदु:
घटक: आयरन (लोहा) और निकेल।
विशेषता: निकेल मिलाने से इस मिश्र धातु की तन्यता ताकत (Tensile Strength), कठोरता और लोच (Elasticity) में उल्लेखनीय वृद्धि होती है।
