What is GJS material?

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 is en GJS 400 18 lt?

EN-GJS-400-18-LT spheroidal graphite cast iron, also known as ductile iron, with guaranteed notched impact toughness at -20°C. In terms of safety, this material offers numerous advantages over cast steel, which is prone to cracking due to its extremely high shrinkage.

What is GGG40?

GGG40 is the most commonly used nodular cast iron alloy and has a predominantly ferritic structure. This cast iron offers excellent machinability combined with good impact resistance, high electrical conductivity, good elongation properties and magnetic permeability. The material cannot be welded.

Is 1865 a chemical composition?

Spheroidal or nodular graphite cast iron or ductile iron is a casting alloy of iron and carbon, carbon being present in the spheroidal form.

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 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 gjs400?

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 difference between SG iron and cast iron?

The difference between traditional cast iron and modern-day ductile iron is the shape of the graphite. While cast iron has small flakes of graphite, ductile iron contains spherical graphite nodules. Because of the spherical shape of the graphite, ductile iron is often called spheroidal iron or nodular 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.

Is 1030 a material specification?

AISI 1030 is a high-carbon steel containing approximately 0.30% carbon that can be hardened by heat treatment to a maximum hardness of approximately Rockwell C 50….AISI 1030 Steel (UNS G10300) in Coil Form.
