What is GJS material?
Cast iron with spheroidal graphite (EN-GJS) is, according to German Standard (DIN) EN 1563, an iron-carbon cast material; its carbon content is almost entirely present in the form of largely spherical “chunks” embedded in the structural iron matrix.
What material is GJS 400 15?
spheroidal graphite iron
Sometimes referenced as a ductile iron EN GJS 400-15 is a spheroidal graphite iron that possesses impact, strength and ductile properties of a different type to that of grey cast iron grades, though with similar machining characteristics.
What is the meaning of cast iron SG 400 15?
According to Indian standard specifications, SG 400/15 means Spheroidal graphite cast iron with minimum tensile strength 400 MPa and 15 percent elongation.
What is GGG40 material?
GGG40 is a very good material grade of ductile iron, which has good tensile strength and yield strength, and especially very high elongation rate. The higher grade will mean the lower elongation, so GGG40 has the highest elongation rate in all ductile iron grades.
What is meant by SG iron?
SG Iron is also known as Ductile Cast Iron, Nodular Cast Iron, Spheroidal Graphite Iron and Spherulitic Cast Iron. This grade of Iron was developed over 60 years ago and in the USA. As the name Ductile Iron suggests this grade of Cast Iron has a degree of ductility.
What is QT450?
QT450-10 ductile iron is carbon in the form of spherical graphite. Its mechanical properties are much better than gray iron but close to steel. It has excellent casting, cutting and wear resistance, and has certain elasticity.
What is ASTM A536?
ASTM A536 refers to the standard specification for ductile iron castings. Ductile iron is also called spheroidal graphite iron or nodular iron. In contrast to gray iron, where the graphite occurs as a network of flakes, the graphite in ductile iron occurs as spheroids.
What is SG material?
SG Iron is also known as Ductile Cast Iron, Nodular Cast Iron, Spheroidal Graphite Iron and Spherulitic Cast Iron. This grade of Iron was developed over 60 years ago and in the USA.
Which is the unique 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 GGG40 3?
GGG40.3. European equivalent grade for Spheroidal graphite cast iron.
How is SG iron made?
To make S.G. Iron, mild steel scrap, Fe-Si, Coke etc. is melted in induction furnace. Once the melt is ready, it is inoculated with small addition of Magnesium or Chromium available in Ferro blends. The metal is then poured into moulds, cooled and fettled.
