NBN 830-01 FGG35 Gray Cast Iron

FGG35 is a type of very high material grade of grey cast iron in Belgium standard NBN 830-01, it is equivalent to EN-GJL-350 in European standard EN 1561.

The Chemical Composition of FGG35 (Belgium: NBN 830-01)
For gray iron casting, there is no any standard mentioned the chemistry composition, so we only suggest the following chemistry based on actual production.

C	Si	Mn	S	P
2.9 - 3	1.2 – 1.5	0.7 – 1.1	max 0.12	max 0.2

Mechanical properties in separately cast test pieces with 30 mm as cast casting diameter
We summarize the mechanical properties for FGG35 gray cast iron according to EN-GJL-350 in European standard EN 1561.

Characteristic	SI-unit	Material designation

0,1% proof stress	N/mm2	228 to 285
Elongation	%	0,8 to 0,3
Compression strength	N/mm2	1080
0,1% compression yield point	N/mm2	455
Bending strength	N/mm2	490
Shear strength	N/mm2	400
Torsional strength	N/mm2	400
Modulus of elasticity	kN/mm2	123 to 143
Poisson’s ratio	-	0,26
