A steel beam can become another steel beam, or a refrigerator, car door or roof panel. when you buy steel you are buying recycled. in addition to being continually recyclable, steels durable characteristics enable many common products to be reused. steel recycling is important to the circular economy as it conserves valuable.
And, the physical characteristics of steel enable it to be recycled continuouslywithout loss of quality or strength. the industrys commitment to recycling reaches beyond the material itself. in fact, greater than 90 percent of the coproducts from the steel making process are reused or recycled. this includes products, like slag, water.

In many applications, high pressures and temperatures necessitate the use of hard tubing, which is incompatible with many other types of fittings. in other applications, such as laboratory instruments, concerns over contamination make the sterility and low outgassing properties of stainless steel tubing and compression fittings attractive.
Carbon steels, which contain between 0.5 and 1.5 carbon: this is the most common type of steel, used for auto bodies, ship hulls, knives, machinery, and all types of structural supports.; low alloy steels, which contain 15 other metals (often nickel or tungsten): nickel steel can withstand high levels of tension and is, thus, often used in the construction of bridges and for making bicycle.
