The cast iron manhole covers with two triangle is made from ductile iron.
Features of the artifacts
The ductile iron manhole covers with triangular lids are designed according to the elastic limit of the material is reached long before the break, thus ensuring a greater margin of safety. The EN 124/94 requires not only the respect of the burden of proof in relation to the class,but also the compliance of the residual value of the arrow.
Security
The spheroidal cast iron manhole with triangular lids, in case of any failure however improbable, do not break into pieces as it happens to those lamellar cast iron, but show only the lesions ensuring in any case the coverage of the cockpit that otherwise would remain unprotected. The spheroidal shape of the graphite produces a lower stress concentration than the lamellar since the spherical form is the one that with equal volume has the lower surface and the matrix of the cast iron is therefore less damaged allowing them to better exploit the mechanical characteristics. Finally, in nodular cast iron graphite nodules exert a stop for the cracks unlike the lamellar graphite which offers a preferential way for their propagation.
