Correct option is B
High-speed steel (HSS) is commonly used to manufacture power hacksaw blades due to its excellent properties, such as:
Hardness: Maintains sharp cutting edges even at high temperatures.
Durability: Offers good resistance to wear and deformation.
Toughness: Withstands the dynamic forces during sawing operations.
Power Hacksaw Blades:
They Designed to cut a variety of materials, including metals and alloys. They Require high strength and wear resistance.
High-Speed Steel (HSS) Contains elements like tungsten, molybdenum, chromium, and vanadium, contributing to its superior properties.
It can operate at higher speeds compared to carbon steels, making it ideal for cutting tools.
