Weaknesses of Stainless Steel

Weaknesses of Stainless SteelIntroductionThis report has been written to give you the reader a basic understanding of untarnished poise. The report will explain how it is made, gives in industry and the strengths and weaknesses of the material.HistoryOriginally known as rust less brand, guileless was officially discovered between the years of 1900 and 1915. There is no exact date of creation as the discovery was the culmination of many an(prenominal) works, the first of which is recorded in 1821. A Frenchman named Berthier put up that when iron is alloyed with chromium it becomes resistant to some acids. Further developments were made in 1872, when three British scientists tried to patient their version of innoxious sword which contained, 30-35% chromium and 1.5-2% tungsten, which they too declared was weather and acid resistant. Three years later in 1875 another Frenchman, Brustlien, discovered the iron used to make spotless had to have a very low carbon content, of only 0 .15%, which was only discovered because ferrochrome became available.Why this material is considered useful or important?Stainless blade is considered to be very useful because it is ductile and malleable and produced to withstand the elements, resisting oxidation and staining.With over 150 various different spotless steel compounds there is hotshot to suit closely applications where other admixtures 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 hard metal with a high melt point.What are the raw materials that are used to produce this material?The raw materials use to produce stainless steels are, a stripped-down of 50% low carbon steel, and at least 10% of chromium. Depending on the grade of stainless steel other elements will be added d uring production including nickel, due north and molybdenum which will give added resistance to various forms of corrosion and sess also reduce the overall weight.What are its applications in industry?Stainless steel is used widely across many industries such asSurgical tools Forceps, needles, scissors and scalpelsKitchen ware Pots, pans, knives and forksArchitectural structures and panels roofing, decorative pieces eg. Empire state building retentivity containers For liquid chemicals to beer or milk.Automotive parts car exhausts, catalytic converters, trim pieces and fastenersMarine Handles, nuts 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 along with its great welding and forming characteristics. 304 is austenitic meaning it is a non metallic consentient solution of iron and carbon which contains no more than 0.08% carbon, and a minimum of 8% ni ckel and 18% chromium316 is the most common form of stainless steel after 304 and is often referred to as marine/ operative 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 hard 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 environment 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, chemical, physical, etc. mechanistic properties of stainless steel are its ab ility 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 oxygen 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 range of different environments.Pressure Stainless steels ability to contain high pressures make it ideal for storage containers and piping. ductile 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 there is no specific future applications that stainless will be in demand for it w ill 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
