What is GJS 400?

What is GJS 400?

EN-GJS-400 ductile iron, also called as nodular iron, is a very good and common cast iron. It has good tensile strength and yield strength, and the largest elongation compared with other ductile iron grades. Moreover, it has the best impact property, casting and machining functions.

What is EN GJS 400 15?

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 GJS in 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 the density of ductile iron?

Ductile iron 65-45-12 is one grade in a family of many. Chemistry requirements are not specified in the ASTM A536 standard….Ductile Iron ASTM A536.

UTS 65000
Hardness
Density lb/in3 (g/cm3) 0.256(7.1)

What is the difference between GGG40 and GGG50?

GGG50 is easily machinable and can be used up to about 450 °C. In comparison to GGG40, this material is the ideal choice for applications where the level of wear and tear is higher, such as running wheels and wheel hubs (e.g. sweepers).

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. Graphite flakes in cast iron act as discontinuities in the matrix and thus lower its mechanical proper- ties. The sharp corners of the flakes also act as stress raisers.
