mainly because during the welding process cast iron; being brittle, is prone to cracking. ways to prevents this are to preheat the whole piece to cherry red and when completed allow it to slow cool by wrapping in rock wool.

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.
Is iron wire stronger than steel wire?
Steel - Pure iron is a relatively soft maleable metal - the addition of small amounts of carbon and other elements during the steel making process add strength and hardness. High strength steels have more carbon than low strength steels, but more carbon also adds brittleness after a point. Silicon, Tungsten and Molybdenum are common alloying elements added to iron to make higher strength steels.
How many types of steel are there?
Here are some examples of iron; pig iron, cast iron, wrought iron, ingot iron, enamelling iron, gray iron, white iron chilled iron, malleable iron, ductile iron, compacted graphite iron, alloy iron, abrasion-resistant iron, corrosion-resistant iron heat-resistant iron
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 are pros cons of acrylic fiberglass cast iron bathtubs?
Cast Iron tubs the finish is stronger in most cases then fiberglass BUT there are new acrylic tubs like Americast that are just as strong (and cost the same) as Cast Cast Iron will not shift like the plastic tubs do BUT you do have a lot more heat loss as the mass of the cast iron is hard to keep warm. Acrylic tubs you have to be extra careful what cleaning agents to use as the finish can scratch more easily
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 are common uses of iron?
Iron is used as a parent material in all steels. You can think of steels ans stainess steel types such as ferritic, austenitic, martensitic, duplex, super duplex stainless steels and many more commercial names that has many different categories. Structural steels are used in construction of buildings and bridges. iron as a major component in steel is also used in construction of piping systems in chemical and metallurgical industries as well as in reinforcements during building. These, including car manufacturing as sheet steel and good quality kitchen ware as mainly type AISI304 and AISI303 stainless steels, are major uses of iron.
What is the difference between cast iron and steel?
The term "cast" can be applied to both metals, although steel has a much higher melting point. Casting describes how the metal is formed into shape, not necessarily how it is made. Iron alloys with 0.2 to 2.1% carbon by weight are known as steels, while iron alloys with 2.1% to ~4% carbon by weight are know as cast iron. Casting is also a metal working process to form metal into a particular shape. Cast steel would be steel that has been "cast" into a particular shape. So, cast iron is iron with more than 2% carbon. Cast steel is iron with less than 2% carbon that has been formed in to a particular shape via a metal working process. Also note that cast steel is the manufacturing process for a steel part/plate, and cast iron is another name for pig iron, basically a waste component of steel production. It is very brittle. There are also alloy steels which are made by adding elements other than carbon to the iron. One example is stainless steel. It has a high resistance to rust and is made by adding chromium to the iron.
Is forged iron superior to cast iron?
no cast iron is more superior than foregn iron

Is cast iron different from iron?
cast iron consists of 2% - 4% of carbon in it. cast iron is pig iron remelted and thereby refined together with definite amount of limestone,steel scrap, and spoiled castings. it consists of small % of sulphur, silicon,phosphorus and manganese wrought iron is highly refined iron with a small amount of slag forged out into fibres. it consists of 99% iron. it is almost the purest form of iron. it is highly ductile,rusts extremely quickly, it cannot be heat treated
why were iron tools more difficult to obtain than copper ones ?
Copper melts at a lower temperature than iron. Therefore, in order to remove it from the ore in which it is found, and in order to work it, a hotter fire is needed to for iron than for copper. Making a fire hot enough to extract and work iron is more difficult, so iron tools were more difficult to obtain than copper tools.

What is the difference between a normal skillet and a cast iron skillet?
It depends on what you want to do with the skillet. A deep cast iron pot is idea for deep frying, while a more shallow skillet is best for frying or baking.
The properties difference between mild-steel and cast-iron?
Cast iron is more brittle then mild steel
