S45C Carbon Steel Round Bar

S45C Carbon Steel Round Bar 

Product Overview 

S45C Carbon Steel Round bar is a premium medium-carbon steel widely utilized in the machinery and automotive industries. Known for its excellent strength-to-toughness ratio and superior machinability, S45C is the ideal material for components that require higher durability than low-carbon steels. Whether used in the as-rolled, normalized, or quenched and tempered (QT) condition, our S45C round bars provide stable performance and cost-effectiveness for high-volume production.
