The Long Development of Alloy Steel
During the twentieth century, steel was the dominant engineering material in the industrialized world due to its low cost and versatility.
This steel, containing 12 percent manganese, has the property of becoming harder as it is worked. This made it ideal for certain types of machinery, such as digging equipment. Hadfeld also invented silicon steel, which has electrical properties that make it useful for building transformers. His work showed conclusively that the controlled addition of alloying elements to steel could lead to significant new specialty products. Hadfeld's discoveries, which were well publicized, led many other engineers and steelmakers to experiment with the use of alloying elements, and the period between about 1890 and 1930 was a very active one for the development of new alloys. The first highly systematic investigation of alloy steels was carried out by Frederick W. Taylor and Maunsel White at the Bethlehem Steel Works in the 1890s. In addition to testing various alloy compositions, the two men also compared the impact of different types of heat treatment. The experiments they conducted led to the development of high-speed steel, an alloy steel where tungsten and chromium are the major alloying elements, along with molybdenum, vanadium and cobalt in varying amounts. These steels allowed the development of metal cutting tools that could operate at speeds three times faster than previous tools. The primary application of high-speed steel during the twentieth century was for the manufacture of drill bits.
Military applications were also a major factor in the development of alloy steels. The demand for better armor plate, stronger gun barrels, and harder shells capable of penetrating armor led to the establishment of research laboratories at many leading steel firms. This played a significant role in the development of the science of metallurgy, with major firms like Vickers in the U.K. and Krupps in Germany funding metallurgical research. The most notable discovery that came out of this work was the use of nickel as an alloying element. Nickel in quantities between 0.5 and 5.0 percent increases the toughness of steel, especially when alloyed with chromium and molybdenum. Nickel also slows the hardening process and so allows larger sections to be heat-treated successfully.
The young science of metallurgy gradually began to play a greater role in nonmilitary fields, most notably in automotive engineering. Vanadium steel, independently discovered by the metallurgists Kent Smith and John Oliver Arnold of the U.K. and LeÂ´on Guillet of France just after the beginning of the twentieth century, allowed the construction of lighter car frames. Research showed that the addition of as little as 0.2 percent vanadium considerably increased the steel's resistance to dynamic stress, crucial for car components subject to the shocks caused by bad roads. By 1905, British and French automobile manufacturers were using vanadium steel in their products. More significantly, As stated in www.canadiandriver.com ,Henry Ford learned of the properties of vanadium from Kent Smith and used vanadium alloy steel in the construction of the Model T. Vanadium steel was cheaper than other steels with equivalent properties, and could be easily heat-treated and machined. As a result, roughly 50 percent of all the steel used in the original Model T was vanadium alloy. As the price of vanadium increased after World War I, Ford and other automobile manufacturers replaced it with other alloys, but vanadium had established the precedent of using alloy steel. By 1923, for example, the automobile industry consumed over 90 percent of the alloy steel output of the U.S., and the average passenger car used some 320 kilograms of alloy steel.
The extensive use of alloy steels by the automobile industry led to the establishment of standards for steel composition. First developed by the Society of Automotive Engineers (SAE) in 1911 and refined over the following decade, these standards for the description of steel were widely adopted and used industry-wide by the 1920s, and continued to be used for the rest of the century. The system imposes a numerical code, where the initial numbers described the alloy composition of the steel and the final numbers the percentage of carbon in the steel. The specifications also described the physical properties that could be expected from the steel, and so made the specification and use of alloys steels much easier for steel consumers.
One of the goals of automotive engineers in the 1910s and 1920s was the development of so-called ''universal'' alloy steel, by which they meant a steel that would have broad applications for engineering purposes. While no one alloy steel could serve all needs, the search for a universal steel led to the widespread adoption of steel alloyed with chromium and molybdenum, or ''chrome-moly'' steel. According to www.sheldonbrown.com ,this alloy combines high strength, toughness, and is relatively easy to machine and stamp, making it the default choice for many applications. The final major class of alloy steel to be discovered was stainless steel. The invention of stainless steel is claimed for some ten different candidates in both Europe and the U.S. in the years around 1910. These various individuals all found that high levels of chromium (12 percent or more) gave exceptional levels of corrosion resistance. The terms ''stainless'' is a bit of an exaggeration-stainless steel alloys will corrode under extreme conditions, though at a far slower rate than other steels. It is this resistance to corrosion, combined with strength and toughness, that made stainless steels so commercially important in the twentieth century. The first commercial stainless steels were being sold by 1914 for use in cutlery and turbine blades, and by the 1920s the material was commonly used in the chemical industry for reactor vessels and piping. Stainless steel later found widespread application in the food processing industry, particularly in dairy processing and beer making. By the end of the twentieth century, stainless steel was the most widely produced alloy steel.
After the 1920s, the development of alloys steels was largely a matter of refinement rather than of significant new discoveries. Systematic experimentation led to changes in the mix of various alloys and the substitution of one alloy for another over time. The most significant factor has been the cost and availability of alloying elements, some of which are available in limited quantities from only a few locations. For example, wartime shortages of particular elements put pressure on researchers to develop alternatives. According to www.lincolnmachine.com ,during World War II, metallurgists found that the addition of very small amounts of boron (as little as 0.0005 percent) allowed the reduction of other alloying elements by as much as half in a variety of low- and medium-carbon steels. This started a trend that continued after the war of attempts to minimize the use of alloying elements for cost reasons and to more exactly regulate heat treatment to produce more consistent results. The manufacture of alloy steels changed significantly over the period 1900-1925. The widespread introduction of electrical steel making replaced the use of crucible furnaces for alloy steel processing. Electrical furnaces increased the scale of alloy steel manufacture, and allowed the easy addition of alloying elements during the steel melt. As a result, steel produced electrically had a uniform composition and could be easily tailored to specific requirements. In particular, electric steel-making made the mass production of stainless steel possible, and the material became cheap enough in the interwar period that it could be used for large-scale applications like the production of railway cars and the cladding of the Chrysler and Empire State skyscrapers in New York.
A major refinement in steel manufacture, vacuum degassing, was introduced in the 1950s and became widespread by the 1970s. By subjecting molten steel to a strong vacuum, undesirable gases and volatile elements could be removed from the steel. This improved the quality of alloy steel, or alternatively allowed lower levels of alloy materials for the same physical properties.
As a result of manufacturing innovations, alloy steel gradually became cheaper and more widely used over the twentieth century. As early as the 1960s, the distinction between bulk and special steel became blurred, since bulk steels were being produced to more rigid standards and specialty steels were being produced in larger quantities. By the end of the twentieth century, nearly half of all steel production consisted of special steels.
