This October has been all about pumpkins. Pumpkin spice lattes, pumpkin muffins, pumpkin beer. The list goes on and on, so we wanted to create a “Leveltek” Halloween list full of festive steel, metal and iron decorations.

imagesSteel and iron are important materials in our modern society. Some people may actually interchange the two, but steel and iron are very different. Iron is an element, while steel is an alloy made up of both iron and carbon. An alloy is just a mixture of two or more elements, generally two or more metallic, or one metallic and one nonmetallic. Other elements can be added to steel to create products with different characteristics. Stainless steel is comprised of steel and chromium; this product doesn’t rust and is very durable. Other elements that can be added to steel are silicon and manganese. By adding these other elements, one can control the strength, ductility, and hardness of steel.
Steel is the main product used in construction, as it is much stronger than iron and has better compression and tension characteristics. Iron that contains more than 2% carbon is called pig iron. But iron that contains less than 2% carbon is steel. Pure iron is very soft and susceptible to rust when in contact with moist air, making it unsuitable to be used in construction or in making utensils, cookware, or many other products. Steel, in comparison, can be up to 1000 times harder than pure iron, hence its widespread use in manufacturing many products we use today.
Although steel is much stronger than iron, it is still very malleable and thus able to be manipulated to create certain shapes. Because of it’s properties, it is the most common alloy used today. It is used for manufacturing weapons, vehicles, tools, buildings, and more. One famous building, the Eiffel Tower, was constructed from puddle iron, which is an iron alloy with very low carbon levels. If it was built today though, it would likely be made of steel.
An important form of iron is that found in our bodies. It is used to carry oxygen to the body in the form of hemoglobin. Many foods we eat are rich in iron such as red meat, tofu, beans, and fish. People who are iron deficient can take iron pills, to ensure that they don’t suffer from fatigue and weakness which is common in those with low iron levels. Vegetarians are among those most at risk for iron deficiency.
As you can see, there are many differences between iron and steel. Steel is comprised of iron and carbon, it is malleable, and has a greater strength than pure iron. Iron was very common before steel production became cheap. Today steel is used in manufacturing many products and for constructing bridges, railroads, buildings, and more. So next time someone confuses steel and iron, you can explain just how different they are.
UnknownMany of us are familiar with the fizzy sound that emanates as we pull the tab on a can of beer or soda. There are so many aluminum cans out in the world that 113,000 of them are recycled every minute. According to the Aluminum Association, recycled cans can appear back on shelves in about 60 days.
Where did these cans come from? Back in 1959, Coors created the first all-aluminum beverage container. Also at this time, Coors was paying a penny for each can returned to them. In 1964, Royal Crown Cola introduced RC Cola and Diet Rite in aluminum cans.
Why use aluminum? Before aluminum, beverage makers used steel cans. Aluminum proved to be much lighter and had a better surface for applying graphics than steel. Cans today weigh less than an ounce. Aluminum cans also allow for 100% protection against contaminants, oxygen, and light, according to the Aluminum Association. These cans also do not rust, have one of the longest shelf lives of any packaging, and are tamper-resistant. Aluminum cans are so strong, four six-packs can hold up a 2 ton car! In addition to providing superior beverage packaging, aluminum cans are used for aerosol products and paint.
The problem with the first aluminum cans was their opening mechanism. They required a device called a “church key” to open the cans. It is said that the inventor of the pull tab had to use the fender of his car to open his beer can, as he forgot his church key. He owned a tool company and invented the pull tab. This tab predated the tabs we are familiar with today, the “stay-on tab” invented in 1975.
The aluminum can is still alive and thriving more than 50 years after their invention. This growth can be attributed to the continued popularity of canned soft drinks, and the booming energy drink market. Companies like Red Bull, Amp, Monster, and more are utilizing aluminum cans to house their beverages. In addition to energy drinks, many craft beer brewers are using aluminum cans as opposed to bottles. The Aluminum Association found that almost 400 brewers use these cans, as they provide superior protection from light and oxygen.

Sheffield’s Women Of Steel will be honoured with a classical music concert to launch the new Music In The Round season at the city’s Crucible theatre – boosting their £150,000 statue appeal.

The internationally renowned Ensemble 360 played classics Schumann’s Piano Quartet in E flat and Schubert’s Octet of 1824, at Sheffield Crucible Studio, on Thursday, October 9.

The evening raised money towards a city centre statue to honour the women who kept the steel mills going, making munitions, to help win two world wars. Some of the surviving Women Of Steel from World War Two, now in their 90s, were invited to attend the concert.

They were also invited to meet Deborah Chadbourn, Music In The Round executive director, to show her a maquette of the statue.

Deborah said: “We are proud to support this appeal for these inspirational women with an night of popular classical music everyone will enjoy.”safe_image
