What is ALFORM 700 Steel Plate and Why is It Important?
ALFORM 700 is a high-strength, thermomechanically rolled structural steel plate known for its excellent weldability, cold formability, and exceptional tensile strength. Manufactured under stringent quality controls, ALFORM 700 is engineered to deliver outstanding mechanical performance in demanding industrial environments.
With a minimum yield strength of 700 MPa, this steel plate is widely used in structures that require maximum strength-to-weight ratio. It allows fabricators to reduce material thickness without compromising on load-bearing capacity—resulting in lighter, more efficient designs. This property makes ALFORM 700 highly sought after across sectors like transport, heavy lifting, construction machinery, and pressure vessels.
Industrial Applications of ALFORM 700 Plates
ALFORM 700 plates are a trusted solution for industries that demand high mechanical strength, resistance to dynamic loading, and excellent forming properties. Common application areas include:
- Crane booms and lifting equipment
- Low-bed trailers and heavy transport vehicles
- Construction and mining machinery
- Wind tower segments and support structures
- Structural components in bridges and high-rise buildings
- Load-bearing elements in pressure vessels and tanks
Their ability to withstand fatigue, stress, and challenging environmental conditions makes ALFORM 700 a preferred material in cost-efficient structural engineering.
Mechanical Properties that Define ALFORM 700 Performance
| Property | Typical Value |
|---|---|
| Yield Strength | ≥ 700 MPa |
| Tensile Strength | 780 – 950 MPa |
| Elongation (L0 = 5.65√So) | ≥ 14% |
| Impact Strength @ -20°C | ≥ 27 J |
| Thickness Range | 3 mm to 100 mm |
These mechanical characteristics enable superior formability during fabrication and ensure long-term durability even under fluctuating loads or harsh outdoor conditions.
ALFORM 700 Plate Standards and Equivalent Grades
ALFORM 700 is produced in line with strict international metallurgical standards, typically conforming to specifications related to thermomechanically rolled high-strength steels. Though it has its proprietary composition, its performance often matches or exceeds the standards of:
- EN 10025-6 (S690QL / S700MC equivalents)
- ASTM A514 Grade Q
- DIN StE 700 or QStE 690
- JFE HITEN 780LE (comparative tensile band)
Its performance profile positions it among globally recognized high-strength plates, ideal for OEM and structural projects requiring certification and traceability.
Thickness Range, Dimensions & Supply Sizes
At Champak Industries, we supply ALFORM 700 steel plates in a wide range of sizes to meet diverse structural and fabrication requirements:
- Thickness: 3 mm to 100 mm
- Width: Up to 2500 mm (customized cuts available)
- Length: Up to 12 meters
- Surface Finish: Mill finish or shot blasted + primer coated (on request)
Custom size cutting, edge preparation, and third-party inspection can be provided as per buyer demand or project requirement.
Fabrication, Forming & Welding Characteristics
ALFORM 700 plates are known for their excellent cold formability and weldability, thanks to controlled carbon equivalent and advanced rolling techniques. Here’s what makes fabrication smoother:
- Cold Forming: Suitable for bending, flanging, and edge forming without cracking
- Welding: Compatible with all conventional arc welding methods (MIG/MAG, SAW, TIG)
- Preheating: Usually not required for <25 mm thickness, but recommended for thicker plates or high restraint joints
- Post Weld Heat Treatment (PWHT): Typically not necessary unless stated by project spec
These properties help reduce processing time, fabrication cost, and structural risk during final assembly.
Why Structural Engineers Prefer ALFORM 700 Plates
- Weight Reduction: Allows for thinner sections in high-load applications
- High Fatigue Strength: Withstands stress cycles in dynamic equipment
- Improved Design Flexibility: Enables sleek, modern structural designs
- Optimized Yield-to-Tensile Ratio: Ensures safety without overdesigning
- Corrosion Resistance (with coating): Performs well in outdoor conditions when properly painted or galvanized
This unique combination makes ALFORM 700 the go-to choice for engineers working on mobile cranes, truck frames, towers, and pressure-critical components.

Buyer’s Guide – When to Choose ALFORM 700?
Choose ALFORM 700 plates when your project demands:
✅ Higher yield strength (min 700 MPa) without compromising on weldability
✅ Reduction in structural weight and increase in payload capacity
✅ Better fatigue resistance in mobile, vibrating, or moving structures
✅ Thinner sections for the same performance — reducing cost and material weight
✅ Superior performance over conventional S355 or S460 steels
If your application involves crane construction, lifting equipment, wind tower segments, truck frames, or pressure-bearing containers, ALFORM 700 is a strategic, cost-saving alternative to over-engineered or heavier steel grades.
