Example: Searching for a Low Alloy Steel with P in a concentration between 0.1 and 0.2 % and Si in a concentration between 1 and 2 %.
We know the material and which elements we need in a certain concentration, so we choose "Search by Composition". Low Alloy Steels are found in "Content" so we are selecting it:
We then choose P as an element and type in 0.1 in "Min." and 0.2 in "Max." to define a range of concentration for this element. We click on "Add Filter" and do the same for Si but with 1% as "Min." and 2% as "Max.":
The result is a list of 14 reference materials to choose from.
