Located in the industrial heart of Hamilton, New Zealand, Hemi Metals is a trusted partner for precision manufacturing. We take pride in supplying high-quality materials engineered for performance, and our SAE 52100 round bar and rod are prime examples of this commitment. We understand that our customers rely on consistent, reliable steel to build durable components, which is why we ensure every bar meets the stringent standards required for demanding applications, backed by our local expertise and dedicated service.
The composition of SAE 52100 is a high-carbon, chromium steel, which gives it exceptional characteristics. This specific blend results in outstanding hardness, high wear resistance, and impressive strength after proper heat treatment. These mechanical properties make it a superior choice for parts that must endure significant stress and friction over long periods. It’s this reliable combination of durability and performance that has made 52100 a go-to material for engineers and manufacturers who cannot compromise on quality.
