High Tensile Steel Plates for Construction Machinery

High Tensile Steel Plates for Construction Machinery

Hindustan Steel Corporation supplies construction-grade high tensile plates used in building the world’s toughest machines — from hydraulic excavators and earthmovers to crawler cranes, concrete pump trucks, and bulldozers. Designed to withstand dynamic loads, wear, impact, and stress, these plates deliver exceptional mechanical reliability in challenging field environments.

Where Are These Plates Used in Construction Equipment?

High-strength plates are used for:

  • Boom arms & lifting arms in cranes, loaders, and forklifts
  • Chassis & undercarriages of bulldozers and track-laying vehicles
  • Dump truck bodies, backhoe buckets, load-bearing frames, and cabin reinforcements
  • Telescopic handlers, batching plants, compactors, and piling rigs

These plates are abrasion-resistant, fatigue-toughened, and ideal for equipment working on road projects, mining zones, dams, metros, and infrastructure megasites.

Mechanical Properties Needed in Construction Equipment

The plates we supply are selected for:

  • Yield strength: 450 MPa to 960 MPa
  • Tensile strength: 570 MPa to 1200 MPa
  • Elongation: Min. 14–20% for ductile performance
  • Charpy impact values: Up to 50J at -40°C for tough working climates
  • Hardness: Up to 470 HBW for extreme wear resistance (in wear plate options)

We serve American EPCs, fabricators, and procurement companies sourcing from India.

Chemical Composition of High Strength Construction Steel

While composition varies across grades (S690QL, NAXTRA 70, Weldox 700, etc.), typical alloying includes:

  • Carbon (C): 0.15–0.22%
  • Manganese (Mn): 1.0–1.7%
  • Chromium (Cr): 0.5–1.5%
  • Nickel (Ni): 0.5–2.0%
  • Boron (B): micro-alloyed for hardness boost
  • Low sulfur/phosphorus to ensure weldability and clean toughness

Construction Machinery Plate Grades & Global Standards

We supply both Indian and global equivalents, including:

  • EN 10025-6 S690QL / S890QL / S960QL
  • SAILMA 450 / 550 / 650, SAIL Hiten 550 / 600
  • Weldox / Strenx, Dillimax 690T, JFE Hiten 780 LE
  • ASTM A514 / A517, NAXTRA 70 / 700
  • IS 2062 E350BR/E450BR (for non-critical parts)

Available in shot-blasted, primer-coated, and quenched & tempered (Q&T) finishes.

Available Sizes & Custom Thickness for Machinery Applications

  1. Thickness: 6 mm to 120 mm
  2. Widths: Up to 3000 mm
  3. Lengths: Up to 12 meters
  4. Cutting service: Laser, waterjet, CNC plasma
  5. Tolerances: As per EN 10029 Class A / B

We provide cut-to-fit plate profiles for excavator arms, dump truck bodies, crane booms, etc., with optional edge preparation.

Heat Treatment & Durability Performance

Construction steel plates are delivered in:

  • Q&T (Quenched and Tempered) – for ultra-high strength & impact toughness
  • Normalized – for structural formability
  • TMCP (Thermo-Mechanically Controlled Processed) – ideal for cold-forming components
  • NACE / HIC tested – on request for oil & gas construction zones

These ensure shock load resistance, weld zone stability, and toughness across cold & hot climates.

Fabrication Tips – Bending, Welding, and Cutting

  • Welding: Preheat required for thicker plates (>40mm); low-hydrogen electrodes advised
  • Bending: Minimum radius = 3x plate thickness; no surface cracks on Q&T steels
  • Machining: Compatible with standard CNC milling & boring
  • Formability: Can be cold-formed into booms, arms, and enclosures

We offer fabrication consultation for OEM clients and contractors.
