Who knew? The word drill can mean: a tool for boring holes in metal, wood, stone, bone, teeth, etc.; a type of snail; repetitive physical, military or mental training; a row of planted seeds; a coarse, heavy-duty fabric; or a type of monkey.

When hot steel, iron, and oxygen interact, surface scale is formed. Descaling is done by either scraping the surface using an abrasive and hot water, or by coating it with wet sand or salt prior to rolling.

One of the biggest uses for stainless steel isn't just cutlery. Stainless steel is often used in engines, covering everything from cars to jets. Because of the enormous pressure engines are under, manufacturers needed to be sure the metal wouldn't corrode and weaken.

Around 90% of the steel you're going to run into is carbon steel, but this can have a wide variety of alloying elements. For the most part, though, they'll fall into three groups: Low carbon or mild steels (with up to .3% carbon), medium carbon steels (.3-.6%) and high carbon steels(more than .6% carbon).

It’s important to choose the right steel for each fabrication challenge. Flat steel is suited to manufacturing processes found in the appliance, automotive, construction, machinery, medical, pipe, and tubing industries. Long steel is essential to the automotive, construction, and energy industries.

The term "tin can" is pretty common, but can be deceptive. Lots of cans used for food storage and are actually made of steel, and can be recycled. In fact, the average family goes through about 600 steel cans every year.

If you're looking at your stainless steel cutlery, you may notice tiny numbers on it, reading either something like 18/10 or 301. This is referring to the percentages of chromium and nickel in the alloy. The 301 number is an alloy designation. For normal cutlery use, you won't notice much of a difference.

You've probably seen lots of items made of steel: sinks are made from it; appliances are made of it, and it's a key material used in construction and manufacturing. Do you know what steel is made of, though? It's an alloy of several metals, including iron and carbon.

When making fittings or other equipment that will be used around explosive gases, brass should be your metal of choice. Its properties eliminate sparking, so there is less of a worry of accidental ignition. Let us know the application, and we will help.

You may think all cans are made of tin (aluminum), but that that's not true. The average household uses over 600 steel cans (or other containers) every year. What are steel cans used for? You'll find them used to package paints, solvents, aerosols and even foodstuffs.

Stainless steel is made up of many metals, with chromium being the most important to determining strength. 10.5 percent chromium is required to make the steel stainless. The more chromium that is added to the mixture, the stronger the metal will be.

What exactly is brass? Brass is a metal alloy which is formed by copper and zinc and brass recipes can be tweaked to vary the amount of copper and zinc to create brass with different types of malleable, color and durability properties.

During the Elizabethan era, brass components were essential to the wool industry, which was essential to the British economy. Brass was highly prized and very costly, because one English company had a monopoly on its production.
