Question

2 Match the alloying elements with the effects it has on the properties of ferrous materials Promotes machinability; however, at high levels it may be undesirable Lead Carbon Silicon A B Promotes corrosion resistance and toughness C Once all the alloys are added to the ladle this element is added last and is the majority element in steel Aluminum D Promotes corrosion resistance and to a lesser degree improves toughness especially at low temperatures Sulphur E Second highest element to promote hardenability, can be a deoxidizer and itf combine with Sulphur can reduce susceptibility of the material to crack or tear Copper Iron Nickel F Primary element that promotes hardenability G Promotes corrosion resistance and has good electrical conductivity H Improves machinability; however, should be melted in a well vented facility and should not be used for manufacturing medical or food storage equipment Chromium I Increases strength, used as a deoxidizer and is added to spring steels Manganese J Principally a deoxidizer and used to control grain size/refinement
