S700mc Hot Rolled high strength low alloy Steel Coil—-S700MC (0.75 x 1500 mm coils, hot-rolled and pickled, Grade A) is a high-quality automotive steel product introduced by JBL.
S700MC is a high-strength, low-alloy steel offering excellent mechanical properties and good formability. Its yield strength in the 70 kg/mm² class ensures structural safety and stability while maintaining sufficient ductility, making the material resistant to cracking during stamping and forming processes. The hot-rolling and pickling process yields a smooth, rust-free surface, meeting the stringent surface quality requirements for automotive wiring harnesses and body structures.
Compared to conventional structural steels, S700MC offers significantly improved ductility and fatigue resistance, thanks to advanced steelmaking and rolling technologies. Its low-alloy composition achieves an optimal balance of strength and toughness, further ensuring both safety and lightweighting in automotive applications.

For S700MC and QStE700TM, tensile test specimens are taken in the transverse direction.
Steel Grade | Thickness (mm) | Specimen Direction | Specimen Width | Bending Angle | Mandrel Diameter / Thickness Ratio |
|---|---|---|---|---|---|
S700MC | 1.20 ≤ T ≤ 8.00 | Transverse | b = 25 mm | 180° | 2.0a |
QStE700TM | 1.20 ≤ T ≤ 8.00 | Transverse | b = 25 mm | 180° | 2.0a |
Note: “a” represents the specimen thickness. After the bending test, the outer surface of the specimen shall show no visible cracks.
