For over three decades, Latham Steel in Hamilton has been a cornerstone of New Zealand’s industrial landscape. We are proud to supply high-performance materials, including the exceptionally resilient Alloy Steel Grade 9 Coil. Known for its excellent strength-to-weight ratio, this steel is a go-to choice for engineers and fabricators across the country who demand reliability in challenging environments, from heavy machinery to critical infrastructure projects where safety and durability are non-negotiable.
Alloy Steel Grade 9 achieves its notable strength through a careful balance of elements, primarily chromium and molybdenum. This gives the coil impressive mechanical properties, including high tensile and yield strength, allowing it to handle significant stress without deforming. It also maintains good toughness and impact resistance, even in lower temperatures, making it a versatile and dependable material for demanding structural and pressure-related applications.
