What is the property of cast iron?
A few common mechanical properties for cast iron include: Hardness – material’s resistance to abrasion and indentation. Toughness – material’s ability to absorb energy. Ductility – material’s ability to deform without fracture.
What is FG cast iron?
1.0. GENERAL. This specification governs the quality requirements of Grey Iron Castings having a tensile strength of 260 N/mm2. 2.0.
What is the chemical composition of cast iron?
Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low- and medium-carbon steel.
What are the properties of malleable cast iron?
Malleable iron, like ductile iron, possesses considerable ductility and toughness because of its combination of nodular graphite and low carbon metallic matrix. Like ductile iron, malleable iron also exhibits high resistance to corrosion, excellent machinability.
What is the effect of nickel on cast iron?
The addition of Nickel in cast iron has following effects mainly: It increases impact strength, machinability, toughness. Increases hardenability, but is least effective among hardenability agents. It helps in reducing distortion and cracks in quenching phase of heat treatment.
Is cast iron carbon steel?
Carbon-steel cookware is often compared with cast iron. While the two materials are very similar, carbon steel actually contains less carbon and more iron. Carbon steel is composed of roughly 99 percent iron to 1 percent carbon, while cast iron normally contains 2 to 3 percent carbon to 97 to 98 percent iron.
What is the effect of nickel on cast irons?
Nickel also reduces the carbon content. These factor increases toughness, plasticity and fatigue resistance. The addition of Nickel in cast iron has following effects mainly: It increases impact strength, machinability, toughness.
Is 210g FG 220?
IS – 210 – 1993. Grade – FG – 200/220, FG – 260, FG – 300, FG – 350. All Grades better Corrosion, wear and heat resisting.
What is cast steel material?
Cast steel is a ferrous alloy with a maximum carbon content of approximately 0.75%. Steel castings are solid metal objects produced by filling the void within a mold with liquid steel. Mechanical properties for cast steel are generally lower than wrought steels, but with the same chemical composition.
Is Sulphur a malleable?
ANSWER: No, sulfur is not malleable.
What is the effect of nickel on property of material?
Nickel improves the toughness and strength by refining the grain size. It also prevents scale forming on the material surface. When used with chromium, it improves the hardness, ductility, fatigue resistance and critical cooling rate.
What is the effect of phosphorus and Sulphur in cast irons?
7. What is the effect of phosphorus and sulphur in cast irons? Explanation: Although sulphur stabilizes cementite, it causes brittleness. The same is true for phosphorus, due to which both elements are limited to a minimum quantity.
