Cast Iron does not rust or corrode as steel can
because the cast iron is a ferrous metal
It has austenitic matrix with very good heat and corrosion resistance properties upto 1500 F
Welding electrode specfication for welding of fg260
Pure iron has bad mechanical properties.
Cast iron welding rod is designed for the SMAW process which is built by flux and a filler metal that suits the base metal's chemical & mechanical properties.
Mechanical Properties of Ductile Iron. Ductile iron is characterized by having all of its graphite occur in microscopic spheroidsCast iron is formed by remelting pig iron, and is useful for a variety of engineering purposes.Properties and Uses of Iron. Iron is one of the three magnetic elements (the others are cobalt and nickel). Cast iron is very brittle (it cracks easily

Spheroidal Graphite (Cast) Iron. As the name implies, graphite is present in spheroidal form instead of flakes and compared with Grey Cast Iron it has higher mechanical strength, ductility and increased shock resistance.
As for the most of rough surfaces of cast iron, the color is grey. Such as normal grey cast iron and ductile iron. The ductile iron will be more white than grey cast iron. There are few types of vermicular cast iron, which are black. The white cast iron will show white color. So, cast iron has different color, such as grey, black, white according to different types. However, most of cast iron castings need surface coating, such as painting or electroplate, so they will show different colors than their own.
Ductile iron typically has a dark grey color, similar to that of cast iron. It may also have a slight metallic sheen when freshly cast.
Cast iron mainly includes grey cast iron, ductile cast iron and malleable cast iron. As for ductile iron, it has very wide application, such as Pressure pipes and fittings, Automotive applications, Agriculture, road and construction applications, General engineering applications. As for the specific application of ductile iron, grey iron and malleable cast iron, please refer to the links below.

The mechanical properties are significantly improved.
Free carbon in cast iron refers to carbon that exists in its elemental form within the iron matrix. It appears as graphite flakes or nodules, contributing to the material's unique properties, such as high fluidity during casting and improved machinability. This free carbon distinguishes cast iron from other metals.
