Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in bar/rod form for structural applications
Wrought maraging steel products classify under alloy steel bars/rods.
If lower alloy grades without maraging characteristics
Basic low-alloy compositions fall under non-specialty alloy powders.
