We know stainless steel, low-carbon steels, medium-carbon steels, high-carbon steels and tool steel (silver steel).
Where are they used?
They are used in manufacturing parts and machines for various industries.
5. What gives the addition of manganese, silicon and chromium to steel?
Manganese gives extra strength and toughness. Steel containing 4 per cent silicon is used for transformer cores or electromagnets. The addition of chromium gives extra strength and corrosion resistance.
6. What can be made of mild steels (medium-carbon steels, high-carbon steels)?
Low carbon steels are used in the manufacture of sheet iron, wire, and pipes. Medium-carbon steels are used as structural steels. Both mild and medium-carbon steels are suitable for forging and welding. High-carbon steels are used in cutting tools, surgical instruments, razor blades and springs.
7. What kind of steels can be forged and welded?
Mild and medium-carbon steels are suitable for forging and welding.
8. How can we get rust-proof (stainless) steel?
We can get rust-proof steels by adding chromium to steel.
9. What is used to form a hard surface on steel?
Heating in the presence of carbon or nitrogen-rich materials is used to form a hard surface on steel.
10. What are high-speed steels alloyed with?
High-speed steels are alloyed with chromium and tungsten plus smaller amounts of vanadium, molybdenum and other metals.
My favourite film is “The Lord of the Rings: The Fellowship of the Ring”. It is the first film of the ”Lord of the Rings“ film series, based on the book of the same name by J. R. R. Tolkien. The film was shot in 2001. It was directed by the New Zealand film director Peter Jackson.
The film is set in Middle-earth – a land where such “goodly” races as hobbits, elves, dwarfs and men live. Since the ancient times they have warred with orcs, goblins and trolls. At the beginning of the film we learn about the One Ring – a powerful weapon created by the Dark Lord Sauron – which was occasionally found by Bilbo Baggins, the hobbit.
On his 111th birthday Bilbo had a great party, after which he suddenly departed and left his young cousin Frodo all his belongings, including the magic ring.
A few years later Gandalf, the wizard, visits Frodo to tell him the truth about the ring. A short time after that Frodo and three of his friends leave Shire. They are followed by the Black Riders, who are searching for Frodo and the Ring. On their way they meet a new friend Aragorn.
The Black Riders attacked Frodo and his friends and one of them stabbed Frodo in the shoulder with a cursed knife. Aragorn took Frodo and the hobbits to the Rivendell where his wound was healed and the Fellowship of the Ring was formed to take the One Ring to Mordor and destroy it.
