The main advantage of using alloy steels is that they offer better properties in comparison to most carbon steel grades while costing lower than stainless steel grades. Both grades 4340 and aisi 4130 round bar belongs to the category of low alloy steels. The additional elements included in their chemistry gives the UNS G86200 Round Bar important properties such as good hardenability, higher tensile strength, superior wear resistance as well as good toughness.

Apart from these characteristics, alloying the aisi 4340 steel rod improves other properties like its fatigue strength, resistance to abrasion and impact resistance. There is an increase noticed in alloy steels ductility as well, making it relatively easier to form AISI 8620 Alloy Steel Round Bar. However, this being said, the hardness properties of carbon steel is very high. Because the content of carbon in Carbon Steel AISI 1045 Round Bar is high, the steel inherently has a better hardness, which makes it tougher. Unfortunately, its hardness also makes carbon steel very brittle, and stress in the form of either temperature change or high pressure can crack carbon steels.

Such applications call for a more ductile component like DIN 1.6523 Rod to be used for the production. Ductile alloys permit some levels of flexibility and in turn alloy minor expansion or contraction during temperature change. Ductility is a property, which keeps the UNS G10450 Cold drawn bar cracking in check, as their expansion or contraction prevents the formation of cracks.
