What Are High Tensile Plates Used For?

Understanding High Tensile Steel Plates

High tensile steel plates are specially engineered carbon-manganese or alloy steels that offer exceptional yield strength, toughness, and weldability. These plates are extensively used across industries where lighter weight, higher strength, and durability are essential to meet design safety and cost-efficiency goals.

The tensile strength typically ranges from 500 MPa to over 1000 MPa, depending on the grade (e.g., S355J2, S690QL, Hiten 550, Sailma 450). Quenching and tempering, or thermomechanical rolling, are applied to enhance structural reliability.

What Makes These Plates “High Tensile”?

The term “high tensile” refers to the plate’s ability to resist stretching, deformation, and impact under heavy load without permanent damage. These plates are preferred for structural parts exposed to cyclic loading, dynamic stress, or high pressure.

Compared to mild steel, high tensile plates can reduce component weight by up to 30–40% without compromising strength — a major advantage in automotive, crane, trailer, and heavy equipment design.

Where Are High Tensile Plates Commonly Used?

You’ll find high tensile plates used in:

Material Properties That Matter

Property	Typical Range
Yield Strength	355 MPa to 1100 MPa
Tensile Strength	500 MPa to 1300 MPa
Elongation (%)	12% to 18%
Impact Toughness (Charpy V)	Up to -60°C (Grade Dependent)
Thickness Available	3 mm to 150 mm

Popular Grades of High Tensile Plates

Grade	Standard	Yield Strength	Applications
IS 2062 E350	BIS (India)	350 MPa	Infra, construction, trailers

How High Tensile Plates Are Processed

These plates are made through quenching and tempering (Q+T) or TMCP (Thermo-Mechanically Controlled Processing) to achieve:

• High strength-to-weight ratio
• Improved weldability
• Excellent fatigue resistance
• Uniform thickness & dimensional accuracy

Surface finish options: hot rolled, shot blasted, pickled or primer-coated as per customer needs.

Fabrication & Welding Advice

• Use low hydrogen electrodes for welding
• Preheat above 15 mm thickness for Q+T plates
• Cold forming possible on thinner grades like E350
• Plates up to 100 mm+ can be CNC profiled
• Machining is possible with carbide tools on S690QL+
