1) Oxygen generally reacts with carbon present in steel during solidification and forms carbon monoxide and thus blow holes in cast. Resulting dangerous carbon monoxide may boil inside the laddle. In addition high oxygen level may create high oxide inclusions that are harmful for steel products.

Similarly due to entrapment of hydrogen and nitrogen, ductility of steel is effected.

2) Low carbon steel: when carbon content in steel is less than 0.3 percent than it is called low carbon steel

Medium carbon steel: when carbon content in steel is 0.3 -0.8 percent than it is called as medium carbon steel

High carbon steel: when carbon content in steel is 0.8-1.5 percent than it is called as high carbon steel.

What are two (2) advantages of breathing air, compared with obtaining Dissolved Oxygen from water? (choose two answers) Air is much lighter and easier to move than water making respiration easier Air contains a much higher concentration of Oxygen than water Breathing atmospheric air does not require any loss of water Air-breathing requires no energy to ventilate the respiratory surfaces The reason animals need a continuous supply of Oxygen is to obtain the most energy from their food. make Carbon...
