And because the process of recycling steel is less polluting than making new steel, we've also achieved the following significant savings; in energy use—47% to 74%; in air pollution—85%; in water pollution—35%; in water use—40%.

If steel is heavier than water, why are ships able to float on the sea?

Instead of using up 219kg of steel, we've use only 6kg.

That's 219kg of steel-more tan a fifth of a ton and more than 40 times the cat's weight.

Cracker Jacks has been gamifying its snack food by putting a small prize inside for more than 100 years, he adds, and the turn-ofthe- century steel magnate ( ' , 巨头) Charles Schwab is said to have often come into his factory and written the number of tons of steel produced on the past shift on the factory floor, thus motivating the next shift of workers to beat the previous one.

Well, the main activities in the region were historically steel and paper processing, I think.

A new study of 12,000 workers in 17 countries by Steel case, a furniture-maker which also does consulting, finds that the best way to ensure employees are engaged is to give them more control over where and how they do their work—which may mean liberati

We have to get the steel sheets we need for these desks from new suppliers.

We can perhaps claim compensation from the steel suppliers for failure to deliver on time

Brittleness remains a problem when building steel structures in cold conditions, such as oil rigs in the Arctic.

But the steel shells of hundreds of the ships cracked in the icy north Atlantic, and 12 broke in half and sank.

kimura's team intends to use its temp-formed steel to make ultra-high strength parts, such as bolts.

Most forms of steel abruptly become brittle at temperatures below about -25°C unless they are mixed with other metals.

Now, though a novel type of steel has been developed that resists fractures at much lower temperatures, while retaining its strength and toughness-without the need for expensive additives.

Steel is valued for its reliability, but not when it gets cold.

The resulting steel appears to achieve a combination of strength and toughness that is comparable to that of modern steels that are very rich in alloy content and, therefore, very expensive.

This could reduce the amount of steel needed to make everything from automobiles to buildings and bridges.
