Essential Facts about Cast Iron
There are different kinds of iron casting which come about as a result of the different methodologies employed by the cast iron foundry manufacturers. Cast iron contains approximately 4.5% carbon. This amount of carbon turns it into a brittle material which can’t withstand a lot of stress and it will always break without giving any warnings. But when it comes to compression, cast iron is very resilient. It can take a lot of compression forces without showing any signs of fatigue or failure. This makes it ideal in the manufacture of certain items and machinery which requires the absorptions of large amounts of compression forces.
At the present times, there are basically two broad uses of cast iron. The first is architectural use which includes the manufacture of items both for construction industry as well as the manufacturing industries. In the construction industry, cast iron is widely used making railroads, bridges, pillars, pipes, gates, etc. It is also used in the manufacture of motor vehicle engine block especially the compacted graphite iron casting which has become the material of choice in the application of V technology for engine blocks. One observation about these structures will reveal that they are high compression items because they support extremely large loads and using a weaker material is a recipe for imminent disaster.
The other use of cast iron is in the manufacture of kitchen wares. Cast iron foundry manufacturers have developed a number of cooking items such as cast iron pans, pots, kettle as well as grills. These items presents a number of benefits as opposed to the use of other cookware made from materials like aluminum. Cookeries from cast iron are excellent heat conductors and they allow for better heat distribution during cooking. They also have non-stick characteristics and this makes food not to stick on the pans during the cooking process.
Even though it has a lot of benefits, cast iron also have a number of weaknesses which must be considered very strongly especially in the view of construction structures. This metal is very weak with regards to tension and the structures should be checked on regular basis for any signs of failures. Replacements should be made the moment such signs are detected. The metal is also prone to rusting and corrosion amidst other kinds of deterioration. These can however be averted by using an appropriate coating to prevent it from the agents which might make it to get eroded or form rust.
