What is the percentage of carbon in FC 250 grey cast iron?
1.5-4.3%
Grey Cast Iron (Gray iron) is so called because of the colour of the fracture face. It contains 1.5-4.3% carbon and 0.3-5% silicon plus manganese, sulphur and phosphorus. It is brittle with low tensile strength, but is easy to cast. The all data in this documents is referred to Chinese standard of GB/T 9439-1988.
Is grey cast iron cheap?
The popularity of grey cast iron components (gray iron castings) is because grey iron is one of the cheapest types of iron castings to produce.
What material is FC250?
JIS G5501 FC250 Gray Cast Iron. JIS G5501 FC250 gray iron material grade, including its application, mechanical properties, chemical composition, and Equivalent Grade.
What is the hardest that grey cast iron can be?
Because of their austenitic matrix and with flake graphite, the high-nickel cast irons are the toughest of all cast irons.
Why is white cast iron called white?
White cast iron is named after its white surface when fractured due to its carbide impurities, which allow cracks to pass straight through.
Is gray iron magnetic?
Magnetic Properties The actual graphite structure and the type of grey iron influence properties such as permeability, coercive force and hysteresis. All grey irons exhibit ferromagnetism except austenitic grades.
