Nestled in the heart of Hamilton’s industrial landscape, Latham Steel is a trusted partner for high-quality steel solutions. Our commitment to local manufacturing means we provide reliable, accessible materials, forged with the same integrity that has defined our community for generations. When you choose our AISI 1045 carbon steel bars, you’re not just getting a product; you’re gaining the assurance of a supplier deeply invested in the success of New Zealand’s engineering and manufacturing sectors, delivering strength and precision right to your doorstep.
The composition of AISI 1045 steel is a straightforward balance of carbon and iron, with a carbon content of around 0.45% giving it a notable boost in strength over milder steels. This mid-range carbon level provides an excellent combination of toughness and durability. It can be heat treated to further enhance its mechanical properties, offering good wear resistance and a tensile strength that makes it a workhorse material for countless demanding applications where reliable performance is non-negotiable.
