Ductile iron

Plastic water line is lighter and easier to work with as well as cheaper. These new plastic water lines also have a high life expectancy and a low corrosion rate. Plastic pipe does not collect the sediment on the pipe like cast and ductile. This is because of the low friction in the pipe between the water and pipe. Plastic pipe keeps water flowing without bursts, flooding, or disruptions. There are four different types of plastic water main you can use, C900, C905, C909, and HDPE fuse-able pipe. Since this water line is made from plastic there is no need to wrap this pipe with poly-wrap to prevent corrosion. I see plastic water line becoming the preferred pipe in 5 to 10…

it has other benificial products as well. These include; high tensile strenght, ductility, corrosion resistant, low thermal expansion and is able to be soldered. So having these properties make it the clear option for use in electrical wiring. High Carbon Steel (Drill Bits): Steel is considered carbon steel when there is no specified minimum content of a certain metal such as; chromium, titanium, nickel etc. As the carbon percentage of steel rises, it will have the potential to become stronger…

2. RESEARCH ON THE STRUCTURE OF METALS AND TYPES OF BONDING. What are metals? 24% of our planet’s mass is metal. They are used as mainly because of their properties; metals are strong, ductile, have high melting points and are excellent conductors of electricity. Other properties of metals are given below: • Can be made stronger by alloys and heat treatment. • Easily machined. • Most of them are heavy. • Susceptible to corrosion. Metals can be divided into two; Ferrous and Non-ferrous. Ferrous…

Oxygen and Iron. Hypothesis: Independent Variables Dependent Variables Controlled Variables • Iron wool ball – When it is dipped in various types of liquid it may react to the oxygen in the liquid and chemical changes happen eg: Colour change = rusting • Thermometer – predicting the temperature of the iron wool ball below the room temperature • No substances or variable be kept the same If the off chance that the Iron wool ball is plunged in various sorts of liquid then the…

Copper is great for electrical infrastructure because the metal is very conductive. This property is a direct result of its structure and atomic makeup. The fact that copper’s structure is a closely packed FCC and has a half filled “S” sub-shell gives it more available electrons to carry a charge. This results in its conductive property. Also notably copper can only be arranged as an FCC, this is caused by its The stress strain curve of copper [2] electron structure. One chemical property of…

Introduction Iron is the foundation of the core of earth. Our very blood contains Iron. In simple words Iron is essential for life. This paper will also address relation of Iron with other types of elements and what makes it different from the others. The importance of Iron is immense in this world and there are many reasons for that. Iron is a brittle, hard substance found on the list of transitional metals in the periodic table on group 8 and period four. It is classified as a transitional…

\par Magnesium: As aluminum has been established as a leading role in automotive industry, the use of magnesium in automobile applications is yet limited. Magnesium exhibits a poor formability whereas aluminum has superior formability at room temperature. The main features of ductile magnesium alloys are that they have homogeneous microstructure which is free of brittle inter-metallic particles and having uniform plastic deformation promoted by its grain size as well as its crystallographic…

In steel, the presence of moisture and air, cause the Iron in steel to start oxidising and in turn forming Iron Oxide (Bayliss & Deacon 2002). This is not very effective for the intended use as vehicles are exposed to all types of weather conditions. On the other hand, the formation of an oxide on Aluminium is what allows it to be more weather resistant than steel. This is because the layer of oxidised aluminium on the surface of the main metal prevents further oxidisation. Even when the layer…

Manganese → also acts as an austenite stabilizer but it also assists in removing oxidation during melting temperature and prevents the formation of iron sulphide which cause hot cracking. Silicon → acts as a de-oxidant and acts as a ferrite stabilizer Molybdenum → adds resistance to localized pitting attack and chlorides attacks Aluminium → lowers hardenability and increases toughness and ductility Columbium → acts as a grain refines in which reduces intergranular corrosion and raises the…
