Which of the following properties is true for medium carbon steel?

• High tensile strength, less ductile, extremely hard

• Higher tensile strength than low carbon steel, less ductile but still good

• Poor weldability, more difficult to machine

• Contains between 0.60% and 1.5% carbon

What is the grain structure characteristic of medium carbon steel?

• Coarse grain size due to low carbon content

• Balanced ferrite-pearlite structure with finer grain size

• Predominantly martensitic structure

• Coarse pearlite structure

Which of the following is an application of medium carbon steel?

• Surgical instruments

• 0.30% to 0.60%

• 0.60% to 1.5%

• 1.5% to 2.0%

Which of the following properties is true for high carbon steel?

• Very high tensile strength, much less ductile, extremely hard

• Higher tensile strength than low carbon steel, less ductile but still good

• Moderate weldability, moderate machinability

• Better corrosion resistance than low carbon steel
