What is S500MC material?
S500MC (1.0984) is a high-strength low-alloy (HSLA) hot-rolled structural steel with a minimum yield strength of 500 MPa. It combines excellent cold formability (180° bending with a mandrel diameter ≤ 2t) and good weldability thanks to its low carbon equivalent, and is widely used in load‑bearing applications such as truck frames, automotive chassis components, and construction equipment.
GNEE Steel has 18 years of experience in steel exports, offering one‑stop processing services from S500MC plate supply to cutting, bending, welding, and more, while maintaining a strict quality control system.

Key Advantages of S500MC Thermomechanically Rolled High Strength Steel
High strength-to-weight ratio: A minimum 500 MPa yield strength allows section thinning (up to 25% weight savings) vs. S355 while maintaining load capacity.
Excellent cold formability: The fine-grained TMCP microstructure supports cold bending (min. 2t radius) and stamping without cracking, with elongation ≥17%.
Reliable weldability: Low carbon equivalent (CEV ≤0.39%) enables most fusion processes without mandatory preheating for typical thicknesses.
Uniform property consistency: Controlled rolling and accelerated cooling deliver consistent mechanical properties along coil length and through thickness.
Satisfactory low-temperature toughness: Impact toughness ≥40 J at -20°C ensures reliable outdoor performance in cold climates.

Fabrication and Processing Guidelines of S500MC Steel Plate
Is S500MC weldable?
Yes, S500MC offers excellent weldability due to its low carbon equivalent (CEV ≤ 0.39%), and can be welded using common fusion processes with preheating generally not required for thicknesses ≤12 mm.
S500MC Steel Plate Weldability
| Welding Process | Recommended Filler Metal (AWS Classification) | Typical Shielding Gas/Flux | Notes |
|---|---|---|---|
| MIG | ER70S-6 | Argon/CO2 Mix | Good for thin sections |
| TIG | ER70S-2 | Argon | Excellent for precision welding |
| Stick | E7018 | - | Suitable for field repairs |
S500MC is well-suited for various welding processes, including MIG, TIG, and stick welding. Preheating is generally not required, but post-weld heat treatment may be beneficial to relieve residual stresses. Common defects include cracking and porosity, which can be mitigated through proper welding techniques and filler selection.
S500MC Steel Plate Cold Forming
This grade is specifically engineered for cold forming operations such as bending, roll forming, stamping and cold flanging. Adhere to the minimum bend radius values in Section 3.2 to avoid edge cracking. Its fine grain structure and low sulfur content also provide good stretch-flangeability.
S500MC Steel Plate Machinability
| Machining Parameter | [S500MC] | AISI 1212 | Notes/Tips |
|---|---|---|---|
| Relative Machinability Index | 60% | 100% | Moderate machinability |
| Typical Cutting Speed (Turning) | 80 m/min | 120 m/min | Use carbide tools for best results |
S500MC exhibits moderate machinability, requiring careful selection of cutting tools and speeds. Carbide tools are recommended for optimal performance, and coolant should be used to manage heat during machining operations.

FAQ
What is S500mc Steel Plate Thickness ?
Standard supply thickness:2.4–16 mm.Other thicknesses are available upon request depending on mill capability.
What does S500MC stand for?
S500MC stands for structural steel (S) with a minimum yield strength of 500 MPa (500) delivered in thermomechanically rolled condition with enhanced cold formability (MC – "M" for thermomechanical rolling, "C" for cold formability) under European standard EN 10149‑2.
Can S500MC be heat treated?
No, S500MC is supplied in thermomechanically rolled condition and post‑delivery heat treatment should be avoided, as it can coarsen the grain structure and reduce yield strength below 500 MPa.
What is the ASTM equivalent of S500MC?
The closest ASTM equivalent to S500MC is A572 Grade 50, though compositional differences exist between the two standards.
