    Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion - and oxidation-resistant need typically an additional 11% chromium.

  2. Steel is iron mixed with carbon and perhaps other metals. It is harder and stronger than iron. Iron with more than 1.7% percent carbon by weight is named cast iron. Steel is different from wrought iron, which has little or no carbon.

  3. J. P. Morgan formed U.S. Steel on March 2, 1901 (incorporated on February 25), by financing the merger of Andrew Carnegie 's Carnegie Steel Company with Elbert H. Gary's Federal Steel Company and William Henry "Judge" Moore 's National Steel Company for $492 million ($15.31 billion today). At one time, U.S. Steel was the largest steel producer ...

    John Henry Irons is a weapons designer who invents high-tech laser guns, protective armor, and sonic sound cannons for the United States military. One soldier, Nathaniel Burke, decides to show just what Irons' weapons can do and sets one of Irons' sonic cannons at the highest power setting, firing the device at an abandoned building. However, the weapon backfires and destroys the building the team is situated in. Irons' partner, Susan "Sparky" Sparks, is crushed by a large slab of concrete in th

    Production of the film Steel started with music producer Quincy Jones and his partner David Salzman. Both Jones and Salzman were fans of the Steel character, especially Jones, who found personal reasons to support the project. Jones stated that he found children's "perspective on the future has changed for the worse, and I hate seeing young people who don't believe in the future. Steel—and I don't want to use that word 'superhero,' because he doesn't fly or anything like that—represents ...

    As well as acting in the film, Shaquille O'Neal contributed to the soundtrack for the film. The single "Men of Steel" has him featured alongside rappers KRS-One, Ice Cube, B-Real, and Peter Gunz. The soundtrack was released on Quincy Jones' record label Qwest Records and included songs featured in the film and songs inspired by it. The album charted in the United States on the Billboard 200 at number 185 and on the Top R&B/Hip-Hop Albums at number 26.

    Steel was released in the United States on August 15, 1997. Steel was considered a large box office bomb on its release with an estimated budget of $16 million, the film grossed just over $1.7 million at the box office.

    Steel was critically panned upon its original release. On Rotten Tomatoes, the film has a rating of 12%, based on 26 reviews, with an average rating of 3.04/10. The site's consensus reads, "Steel is a badly-acted movie that indulges not only in superhero clichés, but also ...

    Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries. Most structural steel shapes, such as I-beams, have high second moments of area, which means they are very

    The shapes available are described in many published standards worldwide, and a number of specialist and proprietary cross sections are also available.

    Most steels used throughout Europe are specified to comply with the European standard EN 10025. However, many national standards also remain in force.

    Steels used for building construction in the US use standard alloys identified and specified by ASTM International. These steels have an alloy identification beginning with A and then two, three, or four numbers. The four-number AISI steel grades commonly used for mechanical engi

    The tallest structures today are constructed using structural steel due to its constructability, as well as its high strength-to-weight ratio. In comparison, concrete, while being less dense than steel, has a much lower strength-to-weight ratio. This is due to the much larger vol

    Structures consisting of both materials utilize the benefits of structural steel and reinforced concrete. This is already common practice in reinforced concrete in that the steel reinforcement is used to provide steel's tensile strength capacity to a structural concrete member. A

    The properties of steel vary widely, depending on its alloying elements. The austenizing temperature, the temperature where a steel transforms to an austenite crystal structure, for steel starts at 900 °C for pure iron, then, as more carbon is added, the temperature falls to a minimum 724 °C for eutectic steel. As 2.1% carbon is approached, the austenizing temperature climbs back up, to 1,130 °C. Similarly, the melting point of steel changes based on the alloy. The lowest temperature at ...

    Steel loses strength when heated sufficiently. The critical temperature of a steel member is the temperature at which it cannot safely support its load. Building codes and structural engineering standard practice defines different critical temperatures depending on the structural element type, configuration, orientation, and loading characteristics. The critical temperature is often considered the temperature at which its yield stress has been reduced to 60% of the room temperature yield stress.

  5. Steel is first rolled to size and thickness and then annealed to change the properties of the final material. Any oxidation that forms on the surface is removed by pickling, and a passivation layer is created on the surface. A final finish can then be applied to achieve the desired aesthetic appearance.
