S355MC steel coil is a hot-rolled, microalloyed High-Strength Low-Alloy (HSLA) steel (EN 10149-2) known for excellent cold formability, high strength (355 MPa yield), good weldability, and high strength-to-weight ratio, making it perfect for structural parts in automotive and industrial sectors needing lightweight yet strong components. It’s available as coils, sheets, or slit coils, offering great performance for cold forming applications like car frames and structural elements. 

S355MC steel coil conforms to the European standard EN 10149-2, which specifies the requirements for hot-rolled flat products made of high yield strength steels for cold forming. The “MC” in the designation stands for “thermomechanically rolled”, which means that the steel is produced by a controlled process that involves heating and rolling at high temperatures to produce the desired mechanical properties.

Mechanical properties of S355MC automotive steel

S355MC is a European (EN 10149-2) high-strength, cold-forming steel, with key equivalents including QStE380TM (German SEW 092), ASTM A572 Gr. 50, FeE355TM (Italian UNI), and SAILMA 350HI (Indian IS 2062), all sharing similar high yield strengths (around 355 MPa minimum) for structural and automotive uses, though minor chemical composition differences exist. 

S355MC Steel Coil Application:

1. Structural parts: S355MC steel coil can be used to make structural parts of the vehicle such as chassis, body panels, and reinforcement components.
2. Suspension components: S355MC steel is used to make suspension components such as control arms, steering knuckles, and axles.
3. Wheels: S355MC steel is also used to manufacture wheels and rims due to its high strength and excellent formability.
4. Exhaust systems: S355MC steel is used in the production of exhaust systems due to its high temperature resistance and durability.
