For manufacturers and engineers across New Zealand, Latham Steel in Hamilton stands as a trusted source for robust and reliable materials. We specialise in supplying AISI 4140 tubing, a versatile chrome-molybdenum steel known for its exceptional strength. Our commitment is to provide high-quality tubing that meets rigorous standards, supporting the demanding projects that drive our nation’s industry forward. When you need a component that combines durability with machinability, our AISI 4140 offerings are engineered to deliver consistent performance you can count on.
The strength of AISI 4140 comes from its specific composition, blending chromium and molybdenum to create a material that responds wonderfully to heat treatment. This allows the tubing to be precisely tempered to achieve a remarkable balance of high tensile strength and good toughness. It’s this combination that makes it so valuable, offering resistance to wear and fatigue that far exceeds standard carbon steels, ensuring it can handle significant stress and impact without failing.
