High-strength chuguna are a kind of gray chugun which receive at modification them Mg magnesium or Ce cerium. Graphite inclusions in these chuguna have spherical shape, call such chuguna high-strength chuguna with spherical graphite (VChShG). The Spherical Graphite (SG) to a lesser extent, than lamellar, weakens the section of a metal matrix and, the main thing, is not such strong concentrator of tension. This circumstance in combination with an opportunity to form necessary structure of a metal matrix allows to give cast iron the high durability, plasticity and the increased impact strength.
Chuguna with the VChShG spherical graphite are used in the industry from 40th years. Such chuguna at high strength to 12 MPas possess also rather high lengthening to 17%. Besides, high-strength cast iron possesses the following mechanical properties:
At a tension durability of VChShG increases in the cyclic mode for 40% (the prisposablivayemost phenomenon) steel does not have that and other constructional materials used for production of pressure head pipes.
Decrease in a limit of endurance of VChShG at 10 million cycles is lower, than at staly.
VChShG is not inclined to deformation aging (a material relaxation), thermal aging is not big and begins only at t = 450 … 550 os.
The threshold of a hladolomkost lies within-60 os (i.e. shock durability remains to a constant).
All types of cast iron including VChShG, possess good foundry properties, and also well resist to corrosion. From such chugun produce elements of building constructions including such responsible as basic parts of reinforced concrete beams, farms, boots under columns, tubings for subway tunnels.
High-strength chuguna with spherical graphite use for replacement of cast steel in products of responsible appointment (are shaky hot rolling, a bed and a frame of rolling mills, hammers and press). In comparison with steel they possess incomparably higher foundry properties and for 8–10% smaller density (the last allows to reduce the mass of cars). Even forgings of responsible appointment from alloyed staly can be replaced with castings from high-strength cast iron with the VChShG spherical graphite. A classical example of they are hard loaded cranked shaft of diesel, including automobile engines on which place great demands for static and fatigue durability. High-strength cast iron is used also for replacement of gray cast iron with lamellar graphite if it is necessary to increase service life of a product or to reduce weight.
The pipe from high-strength cast iron with (VChShG) 400h6000 spherical graphite is applied in the following areas:
External networks and constructions,
Industrial desalination installations;Pipelines for land reclamation;
Sewerage (external networks and constructions);
Pipelines for fire extinguishing systems;
Heat supply (external thermal networks with water temperature to 115 °C);
Electrochemical protection of underground metal constructions.
Perhaps also application of pipes from high-strength cast iron with the VChShG spherical graphite with sizes
400х6000 in other areas. The pipe from high-strength cast iron with (VChShG) 400h6000 spherical graphite has the following advantages:
Simplicity of installation;
