  1. 100 Years of Stainless Steel Book

    As part of the centenary celebrations a special edition book has been commissioned by Marketing Sheffield and produced by Sheffield Newspapers.

    An extraordinary discovery by a remarkable man changed the face of the modern world. Harry Brearley grew up in a poverty stricken family yet the stainless steel he discovered has left Sheffield's fingerprint on some of the world's most iconic buildings and inventions.

    The 100 Years of Stainless Steel book covers the journey from Brearley's childhood to the discovery and huge impact it still has today. Through an impressive collection of photographs it tells the story from inside the steelworks, how stainless steel shaped the city and how it continues to play a major role in 2013.

  2. Fire resistance rating and testing of stainless steels

    Stainless steels do not have an intrinsic 'fire rating'. Tests to assess fire resistance are performed on specific fabrications under precise conditions to BS476 parts 20, 21 (load-bearing elements) and 22 (non-load-bearing elements). Fire tests results on some specific products demonstrate the good fire resisting properties of stainless steels in building and ship bulkhead applications. (186)

  3. Heat tint (temper) colours on stainless steel surfaces heated in air

    A colour chart is shown for guidance on exposure temperatures on 1.4301 (304) type. The factors affecting the degree or depth of colours formed are outlined. These include steel composition, atmosphere, time and surface finish.

  4. Liquid (molten) metal corrosion resistance of stainless steels

    Corrosion risks and selection of stainless steel grades for short-term service in molten aluminium, copper, lead, tin and zinc are discussed.

  5. Maximum service temperatures in air for stainless steels

    Stainless steels are widely used for their good oxidation resistance at elevated temperatures. Although other forms of attack, such as sulphidation and carburisation need to be considered in certain applications, oxidation is of primary importance. Oxidation resistance is dependent, primarily, on the chromium content of the steel. The strength of the steel at the intended service temperature is also important when selecting stainless steels for high temperature service.

  6. Melting temperature ranges for stainless steels

    Stainless steels are alloys and therefore do not melt and freeze at a fixed temperature, as do metallic elements, but over a temperature range, depending on the chemical composition of the steel. Melting range does not directly affect the creep strength or oxidation resistance of individual stainless steels. A table of melting ranges for some of the common stainless steel grades is shown.

  7. Oxidation resistance of stainless steels

    The affects of steel composition on the oxidation resistance of heat resisting stainless steels are discussed. The ferritic stainless steels can suffer strength and embrittlement problems. The austenitic types 1.4845 (310) and 1.4835 (253MA) are good all round choices for oxidation resistance. Maximum temperatures for intermittent service in dry air are lower than continuous service for austenitics. Moist air further reduces service temperatures.

  8. Sulphidation resistance of stainless steels

    The resistance to sulphur containing gasses is related to chromium content, in the same way as oxidation. High sulphur level fuel oils are not normally considered hazardous to stainless steels. Sulphur dioxide, hydrogen and hydrogen sulphide liquid sulphur and sulphur vapour environments are discussed.
