S700MC high strength low alloy structural steel Plates Sheets
S: Structural steel
700: Yield strength
MC: Thermo-mechanically rolled (controlled rolling and controlled cooling)
S700MC high strength low alloy structural steel Plates Sheets is a high-strength, low-alloy structural steel produced via the thermo-mechanical control process (TMCP)—involving controlled rolling and controlled cooling—in accordance with the EN 10149-2 standard; it is specifically designed for cold-formed, heavy-duty structural components.

S700MC Application Areas:
Key characteristics of high-strength automotive steel S700MC:
The S700MC stock currently supplied by JBL includes three common thicknesses:
Thickness (mm) | Applications |
|---|
2.0 | Vehicle body panels, inner door panels |
3.0 | Chassis structural components, reinforcement beams |
4.0 | Heavy-duty vehicle frames, load-bearing components |
Key materials for lightweight automotive design:
Body structural components: A-pillars, B-pillars, crash beams, etc.
Chassis components: Suspension assemblies, subframes
Commercial vehicle chassis rails: Enhancing load-bearing capacity
Engineering considerations for material selection:
When selecting S700MC, several key parameters must be considered:
· Forming Limit Diagram (FLD): To evaluate material performance during complex forming operations.
· Springback characteristics: High-strength steel exhibits 20–30% more springback than conventional steel.
· Die wear: Requires die materials with higher hardness.
· Welding process: Laser welding or resistance spot welding is recommended.
Cost Item | Ordinary Steel | S700MC |
|---|---|---|
Material Cost | Benchmark | +15% |
Weight Savings | 0% | -18% |
Processing Cost | Benchmark | -5% |
Perkhidmatan Life | 5 Years | 8 Years |
Industry Application Case Study:
After a domestic commercial vehicle manufacturer switched to S700MC instead of traditional materials:
· Chassis weight was reduced by 23%
· Production costs decreased by 8%
· Product competitiveness was significantly enhanced
