Correct option is C
Fixtures and jigs are essential tools in manufacturing and machining used for holding, supporting, and guiding workpieces during operations like drilling, milling, and grinding. Steel is the most commonly used material for making fixtures and jigs due to its:
· High strength and durability → Can withstand repeated use and high forces.
· Wear resistance → Reduces deformation over time.
· Machinability and hardness → Can be heat-treated for better performance.
· Corrosion resistance (with coatings or stainless steel options).
Types of Steel Used:
· Mild Steel (Low Carbon Steel): Used for general-purpose jigs and fixtures.
· Alloy Steel (Chromium, Vanadium, Molybdenum): Used for high-precision fixtures.
· Tool Steel (Hardened Steel): Used for wear-resistant applications.
