- A. Are used for automobile parts like gears, axle, shaft, bearings etc.
- B. Are prone to temper brittleness
- C. Have very poor fatigue resistance
- D. Do not contain nickel or chromium or both
Explanation
Low-alloy molybdenum steels in this range are valued for strength, hardenability, and fatigue resistance, making them suitable for gears, axles, shafts, and bearings. The other choices incorrectly describe their properties or composition.
