Steel is an alloy of iron and carbon.
Steel is used in buildings, tools, infrastructure, ships, trains, cars, machines, electrical appliances, and also weapons.
- Manganese Steel.
- Carbon Steel.
- Chromium-Vanadium Steel
- Tungsten Steel.
- Vanadium Steel.
Carbon steels and alloy steels are assigned a four digit number. The first number indicates the main alloying element(s), the second number is for tg (top grade) element, the last two numbers is the amount of carbon, in hundredths of a percent (basis points) by weight.
Metal is naturally occurring and can be found in the Earth’s crust, steel however, is much stronger. Metal tends to be used in surgery equipment and the construction of jewellery due to its malleable nature.
In general, due to its increased strength properties, steel is used more often than iron in large-scale industries like construction. It’s more durable and won’t rust as easily, and also has better tension and compression properties.
