Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.
Most recycled steel is blended with new steel at the steel mill. Scrap steel that is reused directly doesn't change it properties because it has been used. That is unless it has been in certain environments such as ones with hydrogen, hydrogen sulfide etc. Then the steel can become brittle. You might look for information on the National Association of Corrosion Engineers (NACE). They have lots of information on metals and what causes problems.
It is not clear from the question whether the recycled steel is used in its existing state or used as raw material for further fabrication. For the existing steel, you need to track down the original documents such as the ladle analysis and mill certificates certifying the material standards for which the steel was fabricated. Another alternative is take samples and conduct chemical and mechanical tests on the steel. Also the date of when the structure was built from which the steel is recycled may help indicate whether it is (American Society for Testing and Materials) Standard ASTM A7 or ASTM A36 or another type of steel. In most cases, the steel is used as raw material to make new steel. The mill will adjust the additives to produce steel with the required chemical and physical properties to meet the ASTM standards specified.
