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? Information on over 23,000 alloys, including 17,000+ ferrous alloys and 6,000+ non-ferrous alloys. Links to a common MI-21 directory covering nearly 6,500 citations (data reference sources, trade catalogues and Standards) and contact details for 520 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 31,000 consumables including around 9,800 covered electrodes, 16,000 fillers and 1,100 fluxes. Links to a common MI-21 directory covering nearly 6,500 citations (data reference sources, trade catalogues and Standards) and contact details for 520 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.

MI-21 in CES Metal Selector

Working with CES Metal Selector, you benefit from the MI-21 data module's broad coverage of over 100 years of WMI's metals data and TWI’s library of metal joining and surface treatment consumables data (welding, brazing, soldering, surfacing, and spraying). CES Selector's 'Find Similar' tool (new for 2013), comparison tables, and visual material property charts help ensure that you make the best choices when facing the challenges of global equivalency or material obsolescence. You can select materials to meet complex performance requirements and apply materials information to optimize materials strategy—for example, supporting cost control or quality initiatives.

What data is included?

The data module covers around 50,000 materials from 520 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?
