How is a paper clip like a skyscraper? How is blood like a car? The answer to both questions is the same. All of these things contain iron.
Iron is one of the most useful metals. Its strength makes it ideal for building things that will last. Yet it can also be easily worked and shaped. People have been using iron for a long time. Iron beads 6,000 years old have been found in Africa.
WHERE IS IRON FOUND?
Our planet contains a huge amount of iron. Scientists believe that Earth's core is about nine-tenths iron. This giant ball of iron generates Earth's magnetic field and makes compasses work.
We can't get at the iron at the center of the planet. But there is plenty of iron in Earth's outer layer, or crust. Iron is the second-most common metal in the crust after aluminum.
Iron is rarely found in a pure state. The purest natural iron comes from meteorites that have fallen from space. Meteorite iron was the first form of iron that ancient peoples used.
Iron is usually found combined with other elements in rocks. These rocks are called iron ores. They are found in many parts of the world.
HOW IS IRON USED?
Iron must be purified from its ores by smelting. In this process, rocks that contain iron are crushed and melted in a very hot furnace. Molten iron is separated out. People first discovered how to do this around 1350 bc. Iron is much harder than bronze, which was the most commonly used metal until that time. Iron made stronger tools and weapons.
Iron's strength and abundance make it especially useful. But most of the iron we use today is in the form of steel. Today, steel is used to make automobiles and ships. It is used for tall buildings, bridges, and for making many kinds of tools.
STEEL IS MADE FROM IRON
Pure iron breaks easily. It also combines with oxygen in the air. This combination produces the flaky, reddish material we call rust. For this reason, most of the iron we use today is not pure.
Iron can be made much stronger if it is heated together with a bit of carbon. Iron and carbon combine to make steel. Nearly all the iron mined today goes into making steel. Steel can be formed into many sizes and shapes, depending on how it is used.
Small amounts of other elements can be added to steel. For example, adding chromium and nickel makes stainless steel.Stainless steel stays shiny and resists rust. It is used for many things, including pots and pans, forks, knives, and spoons. It is also used to make surgical tools and to patch broken bones.

Most shower curtain rods are made of stainless steel. The stainless steel rods come in a variety of shapes and sizes and usually have a chrome finish.
The three other classes of flatwork are the float finish, broom finish, and steel trowel finish. Float finish involves smoothing the surface using a wooden or metal float. Broom finish includes dragging a broom over the surface for a textured finish. Steel trowel finish is achieved by repeatedly troweling the surface to create a smooth and glossy finish.
Stainless steel is generally easier to keep clean than satin steel because it is more resistant to fingerprints, smudges, and watermarks. Satin steel has a matte finish that can show smudges and marks more easily, requiring more frequent cleaning and maintenance.
who made a fortune as a ruthless steel tycoon
yes. everything is made of tiny particles.
the shower head is made of stainless steel and polycarbonate.
AFAIK, no.
Because refrigerators are made of steel (iron) even though they have nice finish on the outside and magnets are attracted to steel (iron).
To restore stainless steel to its original shine and finish, start by cleaning the surface with a mixture of warm water and mild detergent. Use a soft cloth or sponge to scrub the stainless steel in the direction of the grain. For tougher stains, you can use a stainless steel cleaner or a paste made of baking soda and water. Rinse the surface thoroughly and dry it with a clean cloth to prevent water spots. Finally, polish the stainless steel with a stainless steel polish or a small amount of olive oil to bring back its shine.

A damascus finish would be a finish that replicates the look of damascus steel.
Possible, but, not likely
The finish. Most people prefer stainless with a high shine (polished) finish. Satin has a dull finish to it (unpolished)
The finish of a product would be considered as heavy gauge steel. For instance, an espresso maker could have a heavy gauge stainless steel finish.
to achieve fair finish surfaces, use wrought formwork made up of steel or iron
Most police sidearms have a black or deep blue ("blue steel") finish, although some are made of stainless steel. Rarely, an officer might carry a gun with a nickel finish, which looks like bright chrome.
