460: Minimum yield strength of 460 megapascals (MPa)

MC: Micro-alloyed Steel for Cold Forming

European Standard

EN 10149-2-2013 (Corresponding steel grade: 1.0982)

Core Characteristics

High strength, excellent cold formability

Typical Applications

Automotive structural components requiring good cold formability and medium to high strength, such as automotive frame rails and cross beams.

Chemical Composition Features

S460MC adopts a low-carbon microalloyed design. Typical upper limits of its composition include: carbon (C) ≤ 0.12%, silicon (Si) ≤ 0.50%, manganese (Mn) ≤ 1.60%, with the addition of microalloying elements such as niobium (Nb), vanadium (V), and titanium (Ti). This design improves strength through grain refinement strengthening and precipitation strengthening mechanisms, while ensuring good weldability and formability. Harmful impurity elements such as phosphorus (P) and sulfur (S) are also strictly controlled.

Mechanical Properties

S460MC has a yield strength of ≥460 MPa, a tensile strength generally ranging from 520-670 MPa, and an elongation after fracture of ≥16%. This excellent combination of strength and ductility enables it to meet the dual requirements of stamping formability and load-bearing capacity for automotive structural components.

• S460MC Material Properties

Fine-Grained Steel with Excellent Cold Formability

S460MC is a fine-grained steel. Its good cold formability makes it suitable for room-temperature processing technologies such as stamping and bending, facilitating the manufacturing of complex-shaped parts.

Thermo-Mechanical Control Process (TMCP)

The material is produced using the thermo-mechanical control process (TMCP). By precisely regulating the microstructure through controlled rolling and cooling processes, it achieves high strength and high toughness.

Main Application Scenarios

Due to its excellent comprehensive performance, S460MC is mainly used in manufacturing key automotive structural components, such as automotive frame rails and cross beams. These components require sufficient strength to ensure vehicle safety and good processability to complete manufacturing processes such as cold bending and stamping. The use of such high-strength steel helps reduce weight while ensuring structural strength, aligning with the development trend of lightweighting in the automotive industry.

Formability

Although S460MC has good cold formability, attention must be paid to controlling the deformation amount and bending radius when designing stamping processes.

Weldability

Its low carbon equivalent design ensures good weldability, but it is still necessary to control heat input during welding.
