Give a brief classification of the history of steel development?

high speed steel

High-Speed Steel specifications were developed a few decades ago. Firstly, these are used to form high-speed cutting applications and to manufacture tools. The characteristics may vary with each grade, but all have common properties indulging high resistance to wear and excellent toughness. High-speed steel grades will turn into any soft shape when heated at a temperature of up to 500°C.

Moreover, the chemical composition for high-speed steel grades mixes some or all alloying elements of vanadium, tungsten, chromium, molybdenum, cobalt, and carbon. Degrees with a carbon, tungsten, and vanadium combination can offer maximum wear resistance. Cobalt grades offer hot stiffness and tempering resistance along with lower toughness.

Write a brief note on the history of steel

Robert Mushet invented an air-hardening and self-hardening steel in 1868 and gave it the name Mushet Steel or R Mushets Special Steel. It was one of the unique types of steel that turned into a much harder shape while cooling. It started to utilize engineering tools, and its chemical composition was hidden from people. Now, individuals may know that approximately eight percent tungsten content is required as the main feature of steel. Furthermore, Samuel Osborn & Company of Sheffield, the United Kingdom, patented the mass production of steel products in 1870.

Besides this, American people Frederic Taylor, Maunsel White, and Brit (employees of the Bethlehem Steel Company in Pennsylvania, USA) started experimenting with musket steel to learn more about its unknown features in the nineteenth century. At this point, they discovered that if they added 3.8 percent chromium into the eight percent tungsten steel, they could control its temperature (quench or heat it on its melting point). Hence this formula worked much more efficiently as compared to mushet Steel.

After that, the new form of steel T1 came into action with high speed due to its mass. It was first made in the 20th century by the Crucible Steel Co, New Jersey, America. Moving further, a steel (M2) that is currently used was discovered by the W Breelor in America in 1937.

Define the frequent high-speed steel specifications

The various brand names of the high-speed steel tools were confusing customers when they thought of purchasing at the time. The British Standards Institution made new standards for all types of steel brands and gave one name, BS4659, in 1971. Over time the range of high-speed steel being produced has reduced. Currently, the most popular grades are M2, M35, and M42 which are available in round bars, flat bars, and plates.

M35 HSS: It has good heat-resistant features due to its cobalt properties compared to M2.

M42 HSS: It confers high hardness and efficient cutting performance during the service.

M2 HSS: It shows high wear resistance after the stiffness due to its tungsten molybdenum composition. It beat the T1 steel because of its good cutting power and toughness.
