Latham Steel, based in the industrious city of Hamilton, is a trusted name for high-quality steel throughout New Zealand. We take pride in supplying robust materials for the nation’s toughest projects. Our inventory includes EN 10149-2 S420MC, a high-strength, low-alloy steel specifically engineered for demanding applications. We offer this advanced grade in both sheet and plate forms, providing our clients with reliable, high-performance steel that is perfectly suited for fabrication where strength and durability are non-negotiable.
This particular steel is defined by its carefully balanced composition, which includes micro-alloying elements like niobium and vanadium that enhance its strength without the need for heat treatment. As a result, it delivers impressive mechanical properties straight from the mill, including a minimum yield strength of 420 MPa. This excellent strength-to-weight ratio is complemented by good weldability and formability, making it a highly efficient and practical material for modern engineering and construction.
| Grade | C | Si | Mn | P | S | Al | Nb | V | Ti |
| S420MC | 0,12 max | 0,50 max | 1.6 max | 0.025 max | 0.015 | 0.015 | 0.09 | 0.2 | 0.15 |
| Grade | ReH-Minimun yield strength(Mpa) | Rm-Tensile strength(Mpa) | Nominal thickness(mm) | A-Minimum elongation Lo=5,65√So(%) | Nominal thickness(mm) | A-Minimum elongation Lo=5,65√So(%) |
| EN 10149-2 S420MC | 420 | 480-620 | From3 | 19 | From3 | 19 |
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
The real strength of S420MC is seen in its wide-ranging uses, especially in industries that push materials to their limits. It is a top choice for fabricating heavy-duty equipment, robust vehicle chassis, and structural components in mining and logging. Builders also favour it for architectural elements and support structures where reducing weight without sacrificing integrity is crucial. Essentially, whenever a project calls for a material that is both incredibly strong and surprisingly workable, S420MC sheets and plates from Latham Steel provide the ideal solution.
Latham Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products. Our extensive product range includes Pipes, Tubes, Flanges, Pipe Fittings, Forged Fittings, Sheets and Plates, catering to various industries in Hamilton, New Zealand.
