What is A500 carbon steel?
Steels resistant to climate change.
What is the Difference between carbon steel and hi speed steel?
carbon steels are steels which contain upto 2% carbon and some other trace elements such as silicon, manganese etc., Tool steels have greater amount of alloying than the alloy steels of iron. alloying elemnts include chromium, tungsten, molybdenum, carbon, vanadium, nitrogen in the form of nitrides, manganese, silicon, cobalt. These two mainly differ in the pattern in which they are manufactured. tool steels are manufactured from electric furnace techniques where as most carbon steels are manufactured from conventional melting processes. This is done to exhibit good alloy characteristics and impart greater refined structure which cannot be obtained from the conventional say a cuppola furnace or a bessemer furnace.
What is the difference between mild steel and galvanised steel?
The difference is percentage of carbon, the main alloy element. Those irons containing less than 2% carbon are known as steels while those containing more than 2% carbon are known as pig iron. Pig iron is obtained from iron ore by processing it with coke in a blast furnace. This pig iron is then further processed to reduce the carbon content in different furnaces to obtain steels. These steels can be then further processed to obtain alloy steels, stainless steels by adding elements such as silicon, manganese, chromium, nickel, etc.
Engineering - what is normalizing?
= Normalizing = Heating a ferrous alloy to a suitable temperature (approximately 38°C) above the transformation range and then cooling in air to a temperature substantially below the transformation range. This heat treat operation is used to erase previous heat treating results in carbon steels to 0.4% carbon, low alloy steels, and to produce a uniform grain structure in forged and cold worked steel parts.
What is the effect of silicon in carbon steel?
Silicon is used as a deoxidising (killing) agent in the melting of steel, as a result, most steels contain a small percentage of silicon. Silicon contributes to hardening of the ferritic phase in steels and for this reason silicon killed steels are somewhat harder and stiffer than aluminium killed steels.
