TYPICAL CHARACTERISTICS AND APPLICATIONS

S500MC is a low-carbon microalloyed structural steel, produced via thermomechanical rolling according to EN 10149-2.

It belongs to the high-strength low-alloy steel group, designed for cold-forming applications requiring high yield strength and weight reduction.

It features a fine-grain microstructure achieved through thermomechanical control during rolling, ensuring a minimum yield strength of 500 MPa, good toughness, fatigue resistance, and excellent weldability and formability.

Especially suitable for lightweight structural components where high mechanical strength, good formability, and weight reduction are required: welded structures, formed parts, automotive components, machinery, chassis, frames, supports, and elements under dynamic loads.

DELIVERY CONDITION

S500MC steels are thermomechanically produced in coils and delivered as cut sheets.

Surface finish:
According to EN 10163-2 Class A, subclass 3

Dimensional tolerances:
Flatness exceeding EN 10051
Dimensions according to EN 10051

WELDING AND OXYCUTTING

S500MC offers excellent weldability due to its low carbon content and microalloyed character.

It can be welded using conventional processes such as MIG/MAG, TIG, or manual arc. For thick sections or restrictive conditions, light preheating may be recommended to minimize the risk of cold cracking.

Heat input must be controlled to preserve the fine-grain microstructure. Post-weld heat treatment is usually not required for standard structural applications.

FORMING

Suitable for cold forming. Its high strength allows manufacturing lightweight structural components while maintaining stiffness and load-bearing capacity.

The effect of strain hardening during severe operations should be considered. The recommended minimum bending radius equals the sheet thickness in the transverse direction.

Not designed for prolonged high-temperature use, which could degrade its mechanical properties.

BENDING

Minimum longitudinal and transverse bending radius (R), depending on thickness (e):

• For e ≤ 3 mm, R = 0.8 x e
• For 3 mm < e ≤ 6 mm, R = 1.2 x e
• For e > 6 mm, R = 1.6 x e
