Weaknesses of Stainless Steel

Weaknesses of unblemished SteelIntroductionThis accounting has been written to give you the reader a basic understanding of innocuous blade. The report get out explain how it is made, holds in industry and the strengths and weaknesses of the somatic.History primitively known as rust less marque, blameless was officially ascertained between the years of 1900 and 1915. There is no exact date of asylum as the disco genuinely was the culmination of many an(prenominal) works, the first of which is recorded in 1821. A Frenchman named Berthier found that when iron is alloyed with chromium it be fetchs resistant to round acids. Further developments were made in 1872, when three British scientists tried to unhurried their version of unspotted steel steel which contained, 30-35% chromium and 1.5-2% tungsten, which they too declargond was survive and acid resistant. Three years later in 1875 another Frenchman, Brustlien, observed the iron used to contribute stainless had to ha ve a actually low carbon content, of only 0.15%, which was only discovered because ferrochrome became available.Why this material is considered useful or important?Stainless steel is considered to be very useful because it is ductile and malleable and produced to arrest the divisions, resisting oxidation and patch.With over one hundred fifty various different stainless steel compounds there is one to showcase most applications where other metals maybe used.Where is it found?Stainless steel is not found, it is manufactured from various elements depending on its required use. All stainless steel begins as low carbon steel (50% or more) which is combined with 10 to 26% chromium, to create the base of all stainless steels.which is a sullen metal with a high warming point.What be the raw materials that are used to produce this material?The raw materials use to produce stainless steels are, a minimum of 50% low carbon steel, and at least 10% of chromium. Depending on the grade of stainless steel other elements go forth be added during production including nickel, nitrogen and molybdenum which will give added safeguard to various tunes of corrosion and can also reduce the overall weight.What are its applications in industry?Stainless steel is used widely crosswise many industries much(prenominal) asSurgical tools Forceps, needles, scissors and scalpelsKitchen ware Pots, pans, knives and forksarchitectural structures and panels roofing, decorative pieces eg. Empire state buildingStorage containers For liquid chemicals to beer or milk.Automotive parts car exhausts, catalytic converters, trim pieces and fastenersMarine Handles, loco and bolts, frames and fixturesEven down to the most basic nuts and bolts.The most commonly used form of stainless is 304 due to is cost, strength, versatility and finish available on with its great welding and forming characteristics. 304 is austenitic meaning it is a non metallic substantive solution of iron and carbon w hich contains no more than 0.08% carbon, and a minimum of 8% nickel and 18% chromium316 is the most common form of stainless steel after 304 and is often referred to as maritime/ functional grade stainless. Due to the fact that 316 is sold as a marine grade of stainless it has to resist chloride corrosion caused by salt water, so the addition of molybdenum is required. Molybdenum is a silver coloured element which has an extremely high melting point and when alloyed with steel becomes very unvoiced and resistant to salt corrosion. This is why 316 is suitable for marine use and is also used in surgical and food and beverage applications such as milk storage tanks and piping where a sterile surround is very important. For applications where heat is an issue titanium can added to raise the melting point321 other wise know as aircraft grade stainless has an increased resistance to temperature, withstanding 600-900CWhat are its properties i.e., mechanical, electrical, thermal, chemica l, physical, etc.Mechanical properties of stainless steel are its ability toWhat are its strengths and it limitations?The biggest strength of stainless steel is that it has a very high resistance to oxidation. Although there are many other advantagesLow maintenance Rarely requires cleaningAnti staining and wont rust due to the chromium in stainless steel, which reacts to atomic number 8 creating a protective surface layer over the metal, it is very hard to stain, or create rust.High positive and negative temperatures The ability to withstand temperature allows stainless to be used in a wide icon of different environments.Pressure Stainless steels ability to contain high pressures make it ideal for storage containers and piping.Malleable and ductile Stainless is most commonly produced in coils, sheets, plates, bars and tubes of differing size.What are the future demands and applications on this material?Stainless steel will be use for long time to come into the future. Although the re is no specific future applications that stainless will be in demand for it will be a material which will continue to be used for many years to come purely because stainless steel is 100 recyclable. Even the majority of stainless steel produced today will contain up to 60% recycled material.Knifehttp//www.valleymartialarts.com/index.php?main_page=indexcPath=3_18Kitchenhttp//www.furniturestoreblog.com/2009/01/24/the_ultimate_stainless_steel_kitchen_from_strato.htmlTubeshttp//www.thomasnet.com/articles/metals-metal-products/stainless-steel-tubesChromiumhttp//en.wikipedia.org/wiki/Chromiumhttp//en.wikipedia.org/wiki/Molybdenumhttp//www.wisegeek.com/how-is-stainless-steel-made.htmhttp//www.azom.com/details.asp?ArticleID=965http//en.wikipedia.org/wiki/SAE_steel_gradeshttp//en.wikipedia.org/wiki/Stainless_steelUses_in_sculpture.2C_building_facades_and_building_structures
