Steel Browser View

Steel Browser, or browser in short, displays the list of the alloys for a chosen mode, which can be one of the standards AISI, W-Nr, etc, Proprietary - shows only proprietary alloys, omitting standard names, and All - the list shows all of the alloys in the database, warning - a very long list with almost 4000 names and increasing. Plus, you can add additional search constraints, such as name, maker, technology, etc. More details in the filters section.
Up to 5 alloys can be selected by clicking on the checkbox next to their names, for comparing their composition using the Steel Comparison Graph. Use Graph button to build comparison graph, or Clear button to remove all the selections. You can also individually remove selected items. The toolbar with Graph and Clear buttons automatically pops up when the first alloy is selected, and disappears when the last checkbox is cleared.
Click on the alloy in the list launches Steel Composition And Reference View, which displays detailed information about the alloy record being clicked.

Toolbar Buttons:
Clear - Removes current selection in the list. This option is only enabled if at least one alloy is selected.
Graph - Launches Steel Comparison Graph view to compare compositions of the selected alloys. If only one alloy was selected, its composition is displayed in a graph mode.
Toolbar Buttons(Standard):
Listings - Allows to quickly display group of alloys based on one of the several criteria Standard, Maker, Country and Technology. Each of the listings will clear any existing filter settings and set single criteria for selecting alloys. This is an equivalent of selecting the same field value in more advanced, Filter dialog.
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.
Filter - More advanced Filter Dialog allowing to filter alloys by standard, maker, technology, name pattern, change sort order.
Database - Launches dialog managing databae operations, including synchronization with the knife steel chart on zknives.com. Find - 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.
Help - This help.

Steel Composition And Reference View

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. Known aliases have their own section since 3.0. 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. if there is a standard alloy composition from the same country, then the standard spec is usef, otherwise, 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.

Links:
There are two different types of links in the notes section, blue indicating external links, those require active internet connection to be viewed, and orange, indicating internal links which refer to alloys in the database, no internet connection is required to view those. Since version 2.0 all the reference names are local links and can be navigated.

Toolbar Buttons:
Find - 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 View for the ally being displayed. You can switch back by selecting Info item in the graph view screen.
Elements - Displays the list of the elements for the given alloy, tap on the info icon next to the element name, or on the row to get the description of the effect of the element in the alloy.
Send - Launches Send dialog, which allows to send the alloy record using email, 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 View.
Help - This help.

Steel Comparison Graph View

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 displaying a popup window 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. Ending touch event will close the popup.

Toolbar Options:
- Add Item. This item is enabled if the graph is displaying less than 5 alloy compositions. Selectiing this 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 item is enabled if the graph is displaying more than one alloy compositions. Selecting Remove 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 in one of the alloys selected for comparison. If you are interested in comparing only specific elements instead of all of them, uncheck the elements that you are not interested in, and click the rebuild button to rebuild the graph with just the selected elements. Tap on the info icon next to the element name to get the description of the effect of the element in the alloy.
- Search. Clicking the search button in this view launches search dialog, which is identical to the search dialog launched by Add 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.
- Info. Switches to the Steel Composition And Reference view. 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 displays
Alloy Picker menu, where you can select the alloy for which you'd like to view the composition and reference data.

Filter Dialog

Launched from the Steel Browser View, using toolbar Filter button. Its designed to filter the list of the alloys. Based on the settings of this dialog the search is executed and the results are displayed in the Steel browser view. Controls in the dialog:
Std - Select one of the international steel standards supported in this database, or select Proprietary alloys, or All, this is the same control and function as in the Std option.
Name - Allows to set the name pattern for the alloys. Pattern is a sequence of the characters, which can contain * and ? wildcards, to indicate "any character any number of times", and "single character once" respectively. E.g. A* will match all the steels starting with the letter A, while A? will match alloys starting with the letter A, but only single character following it. Pattern M*S will match any alloy that starts with the letter M and with the letter S, having anything in between those two. You can specify more than one pattern in the Name field, separating them with comma, e.g. A*, M* will include all alloys starting with the letter A or M.
Notes - Filter alloys by the content of the notes field. You can use the same patters described above.
Maker - Filter alloys by maker names. This won't work for anything but All or Proprietary options selected in Std. field.
Tech - Technology used for the alloy making, e.g. PM, CPM, etc. Same as above, has meaning only for All and Proprietary options in Std. field.
Sort - Sort order for the list, ascending or descending.
Once the search button is clicked, current settings are saved in the phone preference storage and next time you launch the application the saved settings are used. You can reset settings by using clear button, or typing new values.
Note - For the fields using pattern search, * is appended at the end of the pattern unless the pattern has either * or _ at the end. Hence, setting pattern M is the same as pattern M*. However, if you want to find 2 teller alloys starting with M, use M_ pattern and * will not be appended.
