Tungsten in steel
A
Improves wear resistance, cutting ability and toughness
B
Refines grain size and produces less tendency to carburisation, improves corrosion and heat resistant properties
C
Improves cutting ability and reduces hardenability
D
Gives ductility, toughness, tensile strength and anti-corrosion properties
Correct Answer: Refines grain size and produces less tendency to carburisation, improves corrosion and heat resistant properties
