As the title suggests, this is a mobile version of the Interactive Knife Steel chart, for the Android OS based smartphones. Detailed information on its use is in the application help file. Given the size constraints of the small device, the layout is different compared to the table layout based user interface in the online chart. Functionality mainly is the same, but there still are differences. Mobile chart is functional without active internet connection. Links to web pages from the steel notes will not work without connection to the internet, however steel compositions, name references, notes and internal links go other alloys are available offline. Usually, the application database is a snapshot of the online database close to the release date. However, starting with version 2.0 the updates for the steel data can be downloaded from the central database automaticaly, keeping your phone database always up to date.
Steel Browser- Main view of the application, displays the list of the alloys corresponding to the current filter. Alloys can be filtered by several criteria, including standard, i.e. one of the supported international steel standards, or proprietary alloys only, or All. Also, alloys can be filtered by name pattern, content of the notes, technology used to make them, etc. Listings menu option allows to quickly switch between the Standard/Maker/Technology/Country, while Filter menu option allows to specify several filtering options simultaneously.
Special type of listings is Recently Viewed. As its name suggests, choosing this menu displays last 50 alloy records viewed by the user, ordered in reverse chronological order, i.e. last viewed is displayed first.
Search - Starts search dialog which allows to search for the alloy by name, clicking on the alloy in the search list launches the Steel Composition And Reference View, displaying detailed information about the alloy. Search option ignores filter and current standard settings, performing search across the entire database.
Checking the checkbox next to alloy name (up to 5) marks the alloy for composition comparison. Selecting Graph button will build the graph for the selected alloys.
You can clear the selection by selecting the Clear button.
Steel Composition And Reference Activity- Displays detailed information about the selected alloy record. Including its composition, and cross-reference data: names in different international steel standards and similar alloys form other makers listed under the same standard names. Any additional information regarding the particular alloy is displayed under its notes section.
For many alloys the exact composition is not available in the database. Just the reference information, which alloy(s) are they equivalent to. In the case of missing composition, it is generated based on other alloys in the same reference group. Range for each element is calculated as the lowest and highest value for that element in all compositions available for the reference group. If the composition is generated, corresponding message is displayed in the view.
There are two different types of links in the notes section, blue indicating external links, those require active internet connection to be viewed, and green indicating internal links which refer to alloys in the database, no internet connection is required to view those.
Search - Starts search dialog which allows to search for the alloy by name, clicking on the alloy in the search list launches the Steel Composition And Reference View, which displays detailed information about the alloy.
Graph - Starts Steel Comparison Graph Activity for the ally being displayed. You can switch back by selecting Menu/Info item in the graph activity screen.
Send - Launches Send dialog, which allows to choose email application to send the alloy record, includes everything that is being displayed in the window. Automatically generates email subject and body, using text/html format. Which means, the generated email will have valid links.
Browser - Switches back to Steel Browser Activity.
Steel Comparison Graph Activity- Displays a graph of the alloy(s) chemical composition. Mainly designed to use for comparison of two or more, up to 5 alloys, although it can also display a graph for a single alloy. Graph bars are single color for the element with fixed content in the alloy, and dual color for the elements with a range, e.g. 1.50%-2.50%, in this case bar from 0 to 1.50% will be darker color and the reminder for m1.50% to 2.50% will be a lighter color.
Legend - Push the button to show and hide the graph legend. Displays alloy names and their color coding.
Touch on the bar - Touching any bar on the graph causes a popup with precise values of the given element for all the alloys in the graph. For the graphs bars those are very low height, touch event is still triggered for the height approximately 30% of the screen height from the bottom.
Info - Switches to the Steel Composition And Reference Activity. If the graph view is currently displaying a single alloy, selecting Info option automatically displays composition and reference information for the alloy. If the graph is displaying comparison information for more than one alloy, the Info item first display Pick An Alloy menu, where you can select the alloy for which you'd like ot view the composition and reference data.
Add - This item is enabled if the graph is displaying less than 5 alloy compositions. Selection this menu option launches search dialog, where you can type alloy name and after selecting one in search results, the alloy will be added to comparison graph.
Remove - This menu item is enabled if the graph is displaying more than one alloy compositions. Selecting Remove menu option displays a dialog which has a check list of the alloys for current comparison. By removing checkbox selection and clicking Graph button, a new comparison graph will be built, for the reminder of the checked alloys in the list. The dialog will not allow to remove all checkboxes, at least one of them has to be checked.
Mode - Allows to select the mode in which Graph can be viewed. Mass %, Molar % and Atomic Count. Where:
Mass % - Shows element mass percentage in the alloy;
Molar Mass % - Mass % is converted into molar mass, and percentage is shown relative to the calculated alloy molar mass, which is the sum of the alloy composition element molar masses.
Atom Count - Number of the element atoms in 1000 atoms of the alloy, calculated from element Molar mass and mass;
Elements - Displays show/hide elements menu. Initially graph is built to display all the elements present at least one of the alloys selected for comparison. If you are interested in comparing only several elements instead of all of them, uncheck the elements that you are not interested in and click the graph button to rebuild the graph with just the selected elements.
Help - This help.
Clicking the search button in this view launches search dialog, which is identical to the search dialog launched by Add menu option, but the difference is that clicking the element in the search result list displays the graph for the clicked alloy, without adding it to the existing comparison set.
Integrated Search- Alloys can be searched and viewed without launching Knife Steel Composition database explicitly. Go to your phone Settings widget, select Search option and then Searchable Items option. The list of the searchable items will contain Knife Steel Compositions item. Check it to include knife steels in global search. Now, when you click the search button global search will also include knife steels in search suggestions. Clicking on the alloy item in the list will launch Steel Composition And Reference Activity for the selected record.
