EN-GJL-150 is a low material grade of grey cast iron in European standard EN 1561, it is also named as cast iron GG15 in standard DIN 1691 by Germany and Austria.

The followings are its equivalent grades, chemical composition, mechanical properties, and some photos of grey iron castings made by Dandong Foundry.

EN-GJL-150 Equivalent Grades

Besides GG15 in standard DIN 1691, this grade is also equivalent to the following grades:
ISO 185 - Class 150
GB 9439 - HT150 in China
ASTM A48 - Class 20, or 25 in USA
UNI 5007 - G15 in Italy
UNF - FG15 in Spain
AS 1830 - T150 in Australia
NS11 100 - SJG150 in Norway

EN-GJL-150 Chemical Composition

In any standard, the chemical composition to this grade were not mandatory, they allow iron casting manufacturers to adjust the chemical composition according to the production conditions, as long as the manufacturers could meet the mechanical properties.

However, some standards have given some chemical ranges for reference. C: 3.2-3.5%, Si: 1.8-2.4%, Mn: 0.5-0.9%, P ≤ 0.2, S ≤ 0.2.

EN-GJL-150 Mechanical Properties

Tensile Strength ≥ 150 Mpa
Yield Strength: No Requirement.
Hardness Range: 150 to 200 BH

Only the tensile strength is the quality inspection standard. Other mechanical properties are only for reference unless the buyers have particular requirements.
