Carpenter Technology Corporation has enhanced its online technical information database. The enhancement includes an improved interface and improved search functions. Launched in November 2000, the database allows users to search for and compare data on hundreds of Carpenter's specialty alloys. To date, more than 27,000 users have registered for the free database. With the upgrade, they will be able to edit and save searches, save personal lists of the alloys they use, sort data easily, view information on new alloys, and e-mail datasheets.
