any steel or alloy of iron and carbon having a carbon percentage of above 0.3% is difficult to weld. carbon steel can have maximum carbon percentage of about 2% and cast iron with carbon percentage between 2% to 4%. the welding of any iron alloy with carbon percentage above 0.3% becomes difficult because of the formation of the martensite in the welding areas, heat affected zone etc., the fusion welding process which is usually employed to weld carbon steel and cast iron takes the metal or alloy to their respective melting point (in this case about 1650 C) which is above the austenizing temperature of most steel and cast iron. when the weld is finished it undergoes a process similar to hardening. the nearby non heated parts of the welded material acts as the cold bath resulting in the hardening process which involves sudden cooling for the formation of martensite which is very brittle, any pressure applied will crack the weld immediately. hence before welding the nearby parts of the material to be welded is preheated so that they wont act as any cold bath. but any way cast irons are very difficult to weld than the steels. this is because of the fact that the martensite formed is as a result of trapped carbon atoms in the iron crystal making a distorted body centered tetragonal crystal structure(martensite). higher the percentage of carbon the martensite formation is even better. hence cast irons are especially difficult to weld. design engineers never suggest a welding process for cast iron. cast irons are welded only when there is no other choice but to weld it.

What is differentiate between steel and Cast iron with reference to their carbon percentage and hardness?
iron with 1.5% of carbon by volume or less is called carbon steel and above 1.5% it is called cast iron, hardmess increases with the carbon % i.e. cast iron is harder than carbon steel
Difference between cast iron and mild steel?
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
What is the main constituent metal in mild steel?
The main element of steel is Iron but has been added with carbon to make steel. The main element of steel is Iron but has been added with carbon to make steel.
What is the difference between mild iron and mild steel?
Iron is the pure element, mild steel, or any steel is iron with a little bit of carbon added. The iron becomes mild steel, steel or any other type of steel depending on how much carbon is added to the iron.
What is plain carbon steel used for?
The various uses of carbon steel depend on the amount of carbon added to the alloy; for instance, carbon steel with the lowest amount of carbon is called wrought iron and is used for things like fencing. Medium-carbon steel, also called mild steel, is the type of steel that is used for structural purposes in buildings and bridges. High-carbon steel is used for springs and steel wires, while ultra-high carbon steel is called cast iron and is often used to make pots.
What is differentiate between steel and Cast iron with reference to their carbon percentage and hardness?
iron with 1.5% of carbon by volume or less is called carbon steel and above 1.5% it is called cast iron, hardmess increases with the carbon % i.e. cast iron is harder than carbon steel
The main difference between cast-iron and steel?
Steel is an alloy of carbon and iron. If the percentage of carbon is more than 2% then it is called cast iron.
How is cast iron converted into steel?
Steel is iron mixed with carbon, the amount of carbon changes the specifications of the steel (strength, elasticity,...)
Difference between cast iron and mild steel?
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
What is the difference between cast iron wok and carbon steel wok?
The difference between cast iron and carbon is steel is the percentage of carbon which is present in the alloy. For cast iron this is between 2.5%-6.67% and for steel this is generally lower than 1.9%. Due to these properties the cast iron wok generally spreads the heat more equally and maintains this temperature much easier than the carbon steel wok. Because of this, it takes a bit longer to heat up. The carbon steel wok heats up very fast and is preferably used when a dish does not need to cook very long.
What types of iron is there?
pig iron, wrought iron and cast iron. These are broad classifications used commercially, they can be subclassified. Chemically we say that its pure or impure, contains sulphur/phosphorous/impurities(slag, etc.)/carbon in so and so % range
What the difference between steel and cast iron with reference to their carbon percentage and hardness?
The amount of carbon in iron is greater than 2 percent. Iron, steel is more difficult. Steel is more resistant to damage from iron.
What is the appearance of a metal and carbon combination?
THat would be steel or cast iron.
Is iron a metal used to make steel?
Steel is made of iron to which is added between 0,02 % and 1.67 % of carbon.If you go over 2% of carbon, you'll get cast iron instead of steel.
What did bessemer process do?
burn off excess carbon from cast iron to make carbon steel.
How many types of iron and their compositions?
pig iron or cast iron having 4.5% carbon as an impurity wroght iron having 0.15% of carbon steel having 1% carbon
What are the elements combined with iron?
Cast iron is also known as grey iron. 95% of cast iron includes alloy material. Carbon and silicon are also in the composition of cast iron. Cast iron is used in cooking and engineering applications.
