Correct option is B
High-carbon steel is the most commonly used material for locating and clamping devices due to its high strength, hardness, and wear resistance.
· Locating devices ensure accurate positioning of workpieces in jigs and fixtures.
· Clamping devices hold workpieces securely during machining operations such as drilling, milling, and grinding.
· High-carbon steel (0.6% – 1.5% carbon content) can be hardened and tempered, providing durability and long service life.
· It resists deformation under heavy loads, making it ideal for high-precision fixtures in manufacturing.
