4130 round bar, normally normalized
When 4130 round bar is normalized, a whole new level of applications opens up. This is because the 4130 becomes significantly harder while still remaining ductile. Consequently, the bar has extra strength but also some flexibility so you don’t have to worry about it shattering under force like some other types of hard metal.
Due to these attributes, 4130 round bar is often machined down into gears, shafts, pins, and other engine components.
What should I use it for?
You should use 4130 round bar in applications where you need high strength, lower weight, ease of machining, and ease of welding. Whether that be building your own motorcycle or airplane, or machining parts to go into an engine. Specifically, 4130 is optimal when you need more strength than 1018 steel or aluminum, but more ductility than stainless steel, and you don’t need the weight reduction of aluminum or titanium.
