So, what do these athletes from all over the world competing in various different sports have in common? They all rely on steel to enhance their performance and keep them safe while they compete for the highest honors in their profession.

Here are some of the most prominent ways steel plays its part in winter Olympic sports:

Blades/Edges of Steel

Ice Hockey

Ice hockey is easily the main attraction of winter Olympics as hockey finals are usually the last events of the Games. The same can be said of para ice hockey as well. Athletes glide through the rink on specially-made sledges, or sleds, and have as much, if not more, full-contact than regular ice hockey.

There are several pieces of equipment that enable hockey players to perform at their best, including their skates and sleds. The deciding factor in the quality of skates comes down to the type of steel used in the blades, or runners. Harder types of steel are preferred for less wear and tear and so that athletes do not have to sharpen the blades too often.

That’s why most opt for stainless steel, for its high-strength, hard, ductile and corrosion-resistant qualities. For para ice hockey players, their sleds make or break the game, and materials like magnesium, high-manganese anti-vibration steel and stainless steel give them the edge they need.

Figure Skating

Blades on figure skates look similar to that of hockey skates, but are longer and heavier. Figure skate blades also have the thickest type of blades at 4 to 5mm. These blades were most commonly made of tempered carbon steel coated with chrome, but lighter materials such as stainless steel are becoming more common. At the professional level, many athletes wear skates with high-grade steels that are much more expensive than common skates. A distinct characteristic of these blades is the spiked front toe which gives figure skaters the traction they need for rigorous jumps and spins.

Short and Speed Skating

Like blades for hockey and figure skates, short track and speed skates are also made of stainless steel. Short track skates are slightly curved and shorter than speed skates, with slightly rounded backends for safety.

Speed skates are different from those for short track because the back-end of the blade is detached from the boot. this reduces friction and energy loss. Also, the detached blade allows the blade to remain attached to the ice longer than attached blades.

Skiing and Snowboarding

Steel also plays a crucial part in the construction of ski and snowboard edges. With high-quality steel, athletes can sharpen the edges more frequently, and sharp edges are crucial for carving and turning on snow. Edges are most commonly made of stainless steel, and they are inserted into the body of the ski or snowboard via “teeth” or T-shaped ridges. Most edges have a Rockwell 48 hardness.

Rock-hard Skeleton, Ultra Sharp Blades

Bobsled

There are several variations of bobsled events during the Olympics: 2-man, 4-man and women’s doubles. No matter how many people are on a team, each bobsled has a steel chassis or skeleton and four steel blades attached to the bottom of the sleds. Every team must use the same type of steel for blades used in competition. Much like a car, materials that make up the bobsled must be lightweight yet strong so the athletes have the freedom to steer through the track. During competition, sleds slide through at an average speed of 150 km/hr.

Luge

The luge is considered to be the most dangerous winter Olympic sport due to high speeds and sharp turns of the track. After push off in a seated position, the person or pair lies flat on their backs and steer the sleds with their bodies. Sleds have a pair of steel blades attached to the bottom. Olympic rules prohibit teams from heating the blades before competition as it would decrease friction against ice. Instead, athletes try to maintain the sharpest blades possible.

Skeleton

Opposite of the luge, skeleton athletes race flat on their stomachs, with no brakes. Instead of starting on the sled, the athletes have to sprint for about 40 meters before hopping on. All skeleton sled frames must be made of steel, and blades are usually made of high-quality stainless steel. As for all the “sliding” sports, there are strict rules for the size and weight of the sleds.

Throughout March, The Steel Wire will take an in-depth look at the people of steel. From stories of those who actively play a part in the steel industry to those who are directly affected by the products made from steel, we will bring you features that will illustrate just how significant the industry truly is.

Here’s a preview of what to expect this month:

The Women of Steel

Although the steel industry is often considered a “man’s industry,” more and more women are beginning to pursue jobs in this field. With grit, determination and strength, inside and out, these women now account for 20 percent of the salaried and managerial ranks, and 10 percent of hourly workers. In honor of International Women’s Day, we investigate the challenges that women endured over the years as they pursued work in the field.

Limbs of Steel: How Prosthetics are Powering Athletes with Disabilities

Today’s most driven athletes with disabilities are transforming prosthetics by turning their limbs into sport-specific power tools. From hands shaped like ice axes to blade runners for feet, these prostheses are smarter, lighter, stronger and more efficient than ever before, all thanks to steel. Meet some of the most inspiring athletes out there—men and women who have overcome physical challenges to cross finish lines at record speeds, power across swimming pools and climb the world’s biggest mountains.

The World’s Most Famous Blacksmiths

Blacksmithing is an ancient art that dates back to the Iron Age, when primitive man first began making tools from iron. Since then, there have been a select few blacksmiths who have particularly made their mark on the steel industry. Often times these smiths and their weapons are closely associated with famous figures in time. This article will take a look at some of the most famous of the lot.

Fishing for a Solution: How an Iron Fish is Treating Anemia

Anemia is the most common and widespread nutritional disorder in the world, affecting 2 billion people globally. But Canadian scientists have come up with an ingenious solution to help alleviate the problem. Meet the Lucky Iron Fish—a fish-shaped chunk of iron that’s put into a pot and boiled with lemon to give adults 75 percent of their daily recommended iron intake, and close to 100 percent for kids in nations where anemia is prevalent.

The blades wielded by the Game of Thrones characters have become synonymous with the show itself, and hardcore fans across the world pay a lot of money to get their hands on replicas of the iconic swords, which each have their own special characteristics and names, like Blackfyre, Dark Sister and Longclaw. But, what makes these weapons so extraordinary?

A Mythical, Magical Metal  

The secret behind the swords’ superiority is the material of which they were forged: Valyrian steel. This mythical alloy, manufactured in the ancient empire of the Valyrians, is noted to be exceptionally sharp and tremendously strong, yet lightweight, making it an ideal metal for a sword. Its rippled patterns make it distinctive from other metals, and because of these properties, the steel is quite scarce and very expensive. Yet what makes Valyrian steel swords most unique and powerful is the fact that they are forged with magic spells and dragonfire in a sword making process that was all but lost over the ages.

While the fictitious alloy was more than likely the result of imaginative thinking than the consultation of chemistry books, George R. R. Martin, author of the A Song of Ice and Fire novel series on which the show is based, drew inspiration from real-life ancient weaponry, more specifically Damascus steel, to dream up the material.

Real-life Inspiration

Similar to its imaginary predecessor, Damascus steel, which originated in South India before the Common Era, was primarily used to make long-bladed weapons which were reputed to be tough, shatter-resistant and able to be honed to a sharp, resilient edge.

Additionally, the blades possessed the distinctive rippled patterns which resembled flowing water. It is said that Islamic knights would look at these patterns before a battle to be reminded of the flowing waters of the rivers of paradise, and be reassured that should they fall, their place in paradise would be secured.

Of course, there were no fire-breathing dragons or wizardry involved in the forgery of these blades, and the metal’s properties weren’t as ideal as those of Valyrian steel. The material did give rise to a number of legends, however.

It was believed that a blade made of Damascus steel could effortlessly cut through a rifle barrel, or cut in half a silk scarf falling across the blade. Some even say that Damascus steel swords were the strongest blades used in the Crusades. Whether there is any truth to these legends or not, the swords were undoubtedly extraordinary for their time.

Also like Valyrian steel, the original method of production of Damascus steel was eventually lost, and the manufacturing of the patterned swords ceased around 1750.

Although Damascus steel blades may be long gone, these intricate swords have been reincarnated, albeit fictitiously, and can continue to be admired, thanks to the Game of Thrones series, which airs on Sundays at 9PM Eastern Standard Time on HBO.
