Nestled in the industrial heart of Hamilton, Latham Steel takes pride in being a trusted New Zealand source for premium metal solutions. We are particularly pleased to offer our high-performance Alloy Steel Grade 12 Coil, a material engineered for reliability in the most demanding environments. Sourced with a commitment to quality, this coil stock provides an outstanding combination of strength and fabrication ease, making it an intelligent choice for Kiwi manufacturers and engineers who refuse to compromise on the integrity of their critical components and projects.
The secret to this steel’s capability lies in its carefully balanced composition, which blends chromium and nickel with molybdenum to create a truly robust alloy. This specific formula grants the material excellent tensile strength and a notable resistance to wear and tear. Perhaps its most valued characteristic, however, is its superior toughness, allowing it to maintain its structural integrity and resist cracking under significant stress and pressure, outperforming many standard carbon steels.
