Nestled in the heart of Hamilton’s industrial landscape, Hemi Metals stands as a trusted fixture for quality metal supply. We take pride in sourcing and stocking materials that local industries can rely on, and our C45 Round Bar is a prime example of this commitment. Known for its excellent balance of strength and machinability, this versatile steel grade is a cornerstone for countless projects across the region, delivered with the personal service and local expertise that defines our approach to business.
The C45 grade is a medium carbon steel, appreciated for its straightforward and reliable nature. Its composition strikes a practical balance, offering good tensile strength and durability without being overly difficult to work with. This makes it highly responsive to heat treatment, allowing its properties like hardness and wear resistance to be tailored for specific needs. Essentially, it’s a robust and adaptable material that provides a solid foundation for components that must withstand significant stress and wear in their daily operation.
