EN 10149-2 S420MC is a high-strength low-alloy steel that is used in the automotive industry for structural and safety-related components. This type of steel is often used in chassis and suspension components, as well as in safety-critical parts such as seat frames and airbag components.

It is rust-resistant, making components corrosion-resistant and prolonging life, reducing thickness and consumption, saving labor and energy, etc. Weathering steel is mainly used in railways, vehicles, bridges, towers, and photovoltaics.

S420MC steel plate/sheet is in EN 10149-2 standard, the material number is 1.0972. The equivalent grades of S420MC steel are SEW092 QStE 420TM, NFA36-231 E420D, UNI8890c FeE420TM, ASTM 060XLK, BS1449 HR50F45.
