Valuable and extensive data using standard techniques have been generated in India in the past three decades on mechanical and corrosion properties of various materials which are utilized in different power plants and chemical industries. These data are accessible from individual laboratories either in the form of journal articles or departmental reports. A need has been felt by the  scientific communities that these data generated should be freely available and accessible for scientific analysis and engineering. The Indian data base for information on scientific expertise, research programs and laboratory facilities was made available under the website of the Indian Institute of Metals during 2005. These information are  now  freely accessible to any internet user. However, this data source did not contain information on materials property and published results. In order to add the value to this type of data base, a working group under national committee of the Indian National Scientific Academy (INSA) for CODATA was formed during 2005. The work is being carried out by this group to collect the data from various important laboratories in India, particularly on mechanical and corrosion metallurgy for its free access to the scientific communities

In this data base, for keeping  the quality of the data,  the relevant data generated using  recognized and standard test methods are collected from all important Indian laboratories. It is emphasized that the data collected from such standard methods have lots of engineering value and are comparable to other databases. In addition to basic data, the information generated on the material from plant experience and failure analysis are also added.  To accomplish this task, a common data sheet format has been prepared. This data sheet is in the form of table in which relevant properties determined after conducting Creep, Fatigue, Tensile, Fracture and Corrosion tests on various materials. The data sheets also contain the information on  metallurgical history of the materials along with the data in the form of graphs and microstructures. This paper describes the efforts made in generating this database and its structure. Typical data sheets containing the  materials data and methods used in such data archiving are also presented.
