FERROUS - CAST IRON Scrap

FERROUS - CAST IRON Scrap
Description :

Cast iron scrap is an iron alloy that contains high amounts of carbon. It is a raw material for the production of new steel and cast-iron products. The steelmaking and foundry industries are dependent upon the ready availability of scrap from manufacturing operations and from the recovery of products that are no longer used or needed.

Cast iron is very strong, dense and malleable iron alloy. Cast iron is the primary product of ferrous metallurgy and it is used for repartition in steel production. It is one of the basic constructional materials. Cast iron is widely used in mechanical engineering because of its good casting and durability properties. What concerns durability, it competes only with carbonaceous steel. In modern mechanical engineering almost 75% of extracted cast iron is used in machinery and various metallic products.

With its low melting point, good fluidity, excellent malleability and wear resistance cast irons have become an engineering material with a wide range of applications, like: water waste hatches, lattices, sewer pipes, huge main water pipes and other similar big, heavy and durable stuff.

CAST Iron Scrap is sold as per ISRI - codes 252, 253, 255, 256, 257, 258, 259, 260, 261, 262 and 263. It is generally sold as mix of 253, 255, 257, 261, 262, and 263.
