Answer is:
refines grain size and produces less tendency to carburisation, improves corrosion and heat resistant properties
Explanation:
Tungsten in steel Refines grain size and produces less tendency to carburisation, improves corrosion and heat resistant properties
Answer is:
surface decarburisation
Answer is:
medium carbon steel
Explanation:
Connecting rod is, usually, made from Medium carbon steel
Answer is:
wrought iron
Explanation:
Wrought Iron is the purest form of iron; although it may contain traces of carbon. Wrought iron is least corrosion resistant, It is usually made by ‘‘puddling process’’ and besides iron contains a small quantity of slag. It is very costly and its use has been almost totally replaced by cheaper steel. However, for some components like chain-links and Crane-hooks wrought iron is still the preferred raw material.
