From the heart of Hamilton’s industrial landscape, Latham Steel has built a reputation for reliable, high-quality materials. We are proud to be your local source for Carbon Steel EN-24 Bars, a versatile and high-strength alloy trusted by engineers and fabricators across New Zealand. Our commitment is to provide not just a product, but a dependable partnership, ensuring you receive the precise specifications you need, backed by expert knowledge and a dedication to supporting local industry with superior steel solutions.
The composition of EN-24 steel is engineered for resilience, primarily consisting of iron with key additions of nickel, chromium, and molybdenum. This specific blend gives the bars their notable toughness and hardenability. After a precise heat treatment process, EN-24 achieves impressive mechanical properties, including a very high tensile strength and excellent wear resistance. This makes it exceptionally capable of withstanding heavy loads and intense stress, striking a remarkable balance between strength and the ability to absorb impact without fracturing.
