EN 10111 DD11 DD12 DD13 DD14 Hot Rolled Steel Plate – Chemical Composition
| Steel Grade | C (Carbon) | Mn (Manganese) | P (Phosphorus) | S (Sulfur) | Si (Silicon) | Remarks |
| DD11 | ≤ 0.12 | ≤ 0.60 | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 | Low carbon, excellent cold forming |
| DD12 | ≤ 0.12 | ≤ 0.60 | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 | Slightly higher formability than DD11 |
| DD13 | ≤ 0.12 | ≤ 0.60 | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 | Optimized for deep drawing |
| DD14 | ≤ 0.12 | ≤ 0.60 | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 | Highest formability in the DD series |
Additional Notes:
Low Carbon Steels: C ≤ 0.12% ensures ease of cold forming and stamping.
Mn ≤ 0.60%: Enhances deep drawing capacity and stamping toughness.
P & S ≤ 0.035%: Reduces inclusions and prevents cracking during forming.
Si ≤ 0.035%: Maintains surface quality and cold forming performance.
EN 10111 DD11 DD12 DD13 DD14 Hot Rolled Steel Plate – Mechanical Properties
| Grade | Yield Strength ReH (MPa) | Tensile Strength Rm (MPa) | Elongation A (%) | Features |
| DD11 | 120 – 240 | 240 – 370 | ≥28 | Excellent cold formability, low strength, easy to process |
| DD12 | 140 – 280 | 270 – 410 | ≥26 | Medium strength, still easy for cold forming, good stamping performance |
| DD13 | 160 – 300 | 280 – 420 | ≥24 | Medium strength, good formability |
| DD14 | 180 – 320 | 300 – 440 | ≥22 | High strength cold forming steel, limited deep drawing |
Notes:
ReH: 0.2% yield strength
Rm: tensile strength
A: elongation measured on a gauge length of 5.65√S in a tensile test
Values are typical ranges; actual values should be confirmed by the supplier’s Mill Test Certificate
Click the Button on The Right
Automotive Industry
Body panels, chassis, brackets, reinforcements
Grades DD11–DD14 chosen based on required strength and formability
Furniture and Appliances
Metal furniture frames, cabinets, appliance casings
DD11 and DD12 are preferred for easy bending and stamping
Construction & Light Structural Use
Roof panels, light steel frameworks, small beams
DD13 and DD14 provide higher strength while maintaining reasonable formability
Electronics & Machinery Housings
Enclosures for machines, electrical cabinets
DD14 for slightly higher strength requirements
| Grade | Typical Applications | Notes |
| DD11 | Automotive body panels, brackets, chassis parts | Excellent cold formability; used where low strength and high ductility are required |
| DD12 | Automotive structural parts, appliance panels, light metal frameworks | Medium strength; good stamping performance; still easy to form |
| DD13 | Car body reinforcements, furniture frames, small structural components | Medium strength; balance of strength and formability |
| DD14 | Automotive structural panels, load-bearing thin-walled parts, small machinery housings | High strength; used where slightly higher mechanical performance is needed; deep drawing possible but limited |
1) Branch Office - Spanish-speaking support, customs clearance assistance, etc.
2) Over 5,000 tons of stock in stock, with a wide variety of sizes
3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging
1️⃣ Bulk Cargo
works for large shipments. The plates are loaded directly onto ships or stacked with anti-slip pads between the base and the plate, wooden wedges or metal wires between plates and surface protection with rain-proof sheets or oil for rust prevention.
Pros: High payload, low cost.
Note: Specialized lifting gear is needed and condensation and surface damage must be avoided during haulage.
2️⃣ Containerized Cargo
Good for medium to small shipments. The plates are packed one by one with waterproofing and anti-rust treatment; a desiccant can be added in the container.
Advantages: Provides superior protection, easy to handle.
Drawbacks: Higher cost, decreased container loading volume.
Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling. This guarantees the H-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!
