  • Most decisions about which steel to use are based on a combination of the following factors:What is the corrosive environment? – Atmospheric, water, concentration of particular chemicals, chloride content, presence of acid.What is the temperature of operation? – High temperatures usually accelerate corrosion rates and therefore indicate a higher grade. Low temperatures will require a tough austen...

  • Various types of stainless steel are used across the whole temperature range from ambient to 1100 deg C. The choice of grade depends on several factors:Maximum temperature of operationTime at temperature, cyclic nature of processType of atmosphere, oxidising , reducing, sulphidising, carburising.Strength requirementIn the European standards, a distinction is made between stainless steels and heat...

  • Austenitic stainless steels are extensively used for service down to as low as liquid helium temperature (-269 deg C). This is largely due to the lack of a clearly defined transition from ductile to brittle fracture in impact toughness testing.Toughness is measured by impacting a small sample with a swinging hammer. The distance which the hammer swings after impact is a measure of the toughness...

  • Although stainless steel is much more resistant to corrosion than ordinary carbon or alloy steels, in some circumstances it can corrode. It is 'stain-less' not 'stain-impossible'. In normal atmospheric or water based environments, stainless steel will not corrode as demonstrated by domestic sink units, cutlery, saucepans and work-surfaces.In more aggressive conditions, the basic types of stainles...

  • Stainless steels of various kinds are used in thousands of applications. The following gives a flavour of the full range:Domestic – cutlery, sinks, saucepans, washing machine drums, microwave oven liners, razor bladesArchitectural/Civil Engineering – cladding, handrails, door and window fittings, street furniture, structural sections, reinforcement bar, lighting columns, lintels, masonry supports...

  • Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as...

  • Many elements and materials go through chemical reactions with other elements. When steel comes into contact with water and oxygen there is a chemical reaction and the steel begins to revert to its original form - iron oxide.In most modern steel applications this problem is easily overcome by coating. Many different coating materials can be applied to steel. Paint is used to coat cars and enamel ...

  • It is not known who produced the first steel. Since 200 BC, many cultures have produced steel in one form or another. A British inventor, Henry Bessemer, is generally credited with the invention of the first technique to mass produce steel in the mid 1850s. Steel is still produced using technology based on the Bessemer Process of blowing air through molten pig iron to oxidise the material and sep...

  • Yes, very easily. Steel's unique magnetic properties make it an easy material to recover from the waste stream to be recycled. The properties of steel remain unchanged no matter how many times the steel is recycled.The electric arc furnace (EAF) method of steel production can use exclusively recycled steel.Steel is the world's most recycled material.

  • Steel is very friendly to the environment. It is completely recyclable, possesses great durability, and, compared to other materials, requires relatively low amounts of energy to produce. Innovative lightweight steel construction (such as in automobile and rail vehicle construction) help to save energy and resources. The steel industry has made immense efforts to limit environmental pollution in ...

  • World crude steel production reached 1,414 million metric tonnes (mmt) in 2010. This is an increase of 15% compared to 2009 and is a new record for global crude steel production.

  • Steel is not a single product. There are more than 3,500 different grades of steel with many different physical, chemical, and environmental properties.Approximately 75% of modern steels have been developed in the past 20 years. If the Eiffel Tower were to be rebuilt today, the engineers would only need one-third of the steel that was originally used.Modern cars are built with new steels that are...

  • Most steel is made via one of two basic routes:Integrated (blast furnace and basic oxygen furnace).Electric arc furnace (EAF). The integrated route uses raw materials (that is, iron ore, limestone and coke) and scrap to create steel. The EAF method uses scrap as its principal input.The EAF method is much easier and faster since it only requires scrap steel. Recycled steel is introduced into a fu...

  • Steel is an alloy of iron and carbon containing less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen. Steel is the world's most important engineering and construction material. It is used in every aspect of our lives; in cars and construction products, refrigerators and washing machines, cargo ships and surgical scalpels.
