ZIMSEC O Level Combined Science Notes: Steel making
- The iron from the oxygen lance process is poured into a ladle and
- Small amounts of other metals are mixed with it
- It is mixed with metals such as:
- manganese, cobalt, chromium or nickel is added to create different alloys
- An alloy is a mixture of two or more different metals
- These alloys of iron have different properties with makes them more suited for their intended uses
- These alloys of iron are known as steels
- The properties of each steel and their uses depend on the composition of the steel
- There are several steels
- mild steel-has low carbon content, can be welded and is malleable and ductile
- medium steel-has increased tensile strength, is used to construct buildings,bridges, ships, locomotives, power pylons and to reinforce concrete
- high carbon steels-are used where tough, hard allows are required for example razor blades, surgical instruments and drills
- Alloy steels-these include manganese steel which is very hard, chromium-vanadium steel which is very tough and stainless steel which contains chromium is rust resistant.
