Grey Cast Iron — Facts And Myths


Grey Cast Iron — Facts And Myths

Gray cast iron is a form of traditional cast iron with a stippled graphitic structure. It’s named after the grey color of the black oxide that forms the fracture it Forms, which is primarily due to the presence of ferric oxalate. It’s the most abundant conventional cast iron and the second most popular cast metal based on volume. In addition to being the second most popular, it is also the heaviest. It is typically utilized for making railroad ties, railroad wheels, and railroad bolts because of its high stiffness and ductility.

Because of the high level of ductility, this cast iron has excellent fatigue strength and stress-resistance properties. Additionally, it’s been found that when exposed to high temperatures, grey cast iron (also referred to as ‘Wilton’ steel) develops a crack in its brittle surface which, if left untreated, can lead to corrosion of the interior surfaces. The cracks are so small that they can be removed easily and then repainted. However, the crack grows deeper into the material and must then be repaired or the entire piece could collapse, damaging your property.

Cast iron railings have been made with the aid of a process called cracking or flaking. Cracking involves forcing the castings apart using an abrasive material such as lime, sandpaper or pumice stone. In order for the surface to be open enough to allow the castingings to flow smoothly and cleanly, the pieces need to be pushed into a plasticizer. Once the material has been sufficiently plasticized, the next step is to roll the pieces onto the horizontal position and allow them to dry in between the layers of plasticizer.

In comparison to graphite, grey iron casting is extremely hard and doesn’t yield easily to stress forces. For this reason, the material will generally crack before the flakes completely harden and fall apart. Some experts compare this property to concrete; if you try to compress a concrete slab with the same weight, the outcome is generally less than desirable.

Apart from the appearance, grey cast iron is also used for both the home and commercial sectors because of its strength and wear resistance properties. For example, it’s commonly found in terracotta flower pots, bird cages, railway sleepers, guardrails and stair steps. At the residential level, it’s often seen in garden furniture due to its good heat conductivity and insulation properties. It’s also a popular choice for building claddings because it’s durable, strong and has excellent slip resistance.

This combined with its good aesthetics make it highly desirable in the commercial market.

Like other steels, grey cast iron is subject to corrosion, so expert maintenance and timely repair are important. A well-maintained piece can be expected to last for decades, though it can experience a faster decline in tensile strength and toughness. To prevent the development of cracking, it’s advisable to avoid touching the item in any way. Though it’s a tough and durable material, it’s still susceptible to corrosion so it’s important to take special care when touching the item. A properly maintained piece should retain its original colour and luster for many years.
