MI-21
MI-21 (Metals Information for the 21st Century) comprises two unique data collections—WMI Metals and TWI Consumables—integrated into one tool and backed up by two specialist and authoritative library services. The MI-21 project is coordinated by NAMTEC (the National Metals Technology Centre).
WMI Metals
| What is it? | Part of the World Metals Index (WMI), a vast collection of specifications, standards, trade literature, and datasheets for ferrous and non-ferrous metals. WMI encompasses over one hundred years of metals information dating back to the early 1900s. |
| What is in it? | Data on over 20,000 alloys, including 15,000+ ferrous alloys and 5,000+ non-ferrous alloys. Links to a common MI-21 directory covering nearly 6,000 citations (data reference sources, trade catalogues and Standards) and contact details for 480 suppliers. |
| What is it used for? | Specification, procurement, material selection, design, analysis, manufacturing, maintenance and repair, material identification and equivalents, research. |
| Where does it come from? | WMI is maintained by Sheffield City Library, Yorkshire, UK. |
TWI Consumables
| What is it? | Part of TWI’s library of metal joining and surface treatment consumables data: welding, brazing, soldering, surfacing, and spraying. |
| What is in it? | Data on 27,000 consumables including around 9,000 covered electrodes, 13,000 fillers and 1,000 fluxes. Links to a common MI-21 directory covering nearly 6,000 citations (data reference sources, trade catalogues and Standards) and contact details for 480 suppliers. A guide to welding terminology comprising hundreds of entries for approval/certification organizations, shielding gas classifications, working positions, plus a glossary of common English, French and German welding terms. |
| What is it used for? | Consumables specification, procurement, selection, manufacturing, maintenance and repair, material identification and equivalents. |
| Where does it come from? | TWI (The Welding Institute), a global leader in joining technologies, headquartered near Cambridge, UK. |
MI-21 in GRANTA MI
The MI-21 data module is a powerful addition to any materials library. WMI Metals offers broad coverage of information which is hard to find elsewhere, including historical data. TWI Consumables is a unique compilation of welding related information. And, when you subscribe to the MI-21 data module, you also benefit from a direct information service provided by WMI and TWI. The service, available by email or phone, puts you directly in touch with experts who can resolve metals-related queries based on the full resources of their specialist library collections.
By deploying MI-21 within GRANTA MI, you can provide your organization with a fast, efficient way to search, browse, and use the data - on its own, in combination with other leading materials reference sources (for example, the StahlDat SX steels data), and/or integrated with your in-house materials data.
Viewing MI-21 data via GRANTA MI
What data is included?
The data module covers around 50,000 materials from 480 suppliers. Access to the MI-21 librarian support also allows users to secure additional non-digitised information or receive assistance in carrying out difficult search operations. Data on around 300,000 materials is available through this service.
The service includes information on these materials attributes:
- Chemical composition
- Mechanical properties
- Physical properties
- Equivalent materials
- Heat treatment
- Working
- Fabrication
- Welding
- Machining
- Corrosion
- Fatigue
- Creep
- Creep rupture
- Suppliers
Applications
Using this module, you can answer questions such as the following.
Supply:
- Who supplies Zeron 100 or its equivalents?
- What is JIS H 5112?
Maintenance & repair:
- What can Zeron 100 be welded with?
- What materials match my analyzed chemical composition of Fe%, Cr%, Ni%, C%?
Chemical composition & properties:
- What is the chemical composition of 9SMn28?
- What is the tensile strength of ASTM A182 F51?
Equivalents & alternatives:
- What is the British ‘equivalent' of Z6 CND 16-05-01 and where can it be bought?
- What alternative products are there to Grinox 592 covered electrode?
