SAILMA E410 / E450 / E550 / E650 High Tensile Plates – Stockist & Exporter from India

Hindustan Steel Corporation is a leading supplier of SAILMA high tensile steel plates — produced by SAIL (Steel Authority of India Ltd) for demanding structural, fabrication, and engineering applications. Available in E410, E450, E550, and E650 variants, these plates are known for exceptional weldability, strength-to-weight ratio, and cost-efficiency.

We supply SAILMA plates with mill TC, third-party inspection support, and full export packaging — ready for global infrastructure and fabrication projects.

What is SAILMA Steel? Grades, Meaning & Yield Strength Explained

SAILMA stands for SAIL Medium Alloy, a family of Indian-made high-strength low alloy (HSLA) structural steel plates. The number in each grade (e.g., E410) denotes the minimum yield strength in MPa.

Grade Yield Strength (MPa) Typical Use
SAILMA 410 ≥ 410 General fabrication, trailers
SAILMA 450 ≥ 450 Bridges, offshore platforms
SAILMA 550 ≥ 550 Crane booms, mining equipment
SAILMA 650 ≥ 650 Load-bearing frames, defense
  • Compliant with IS 2062 E410/450/550/650
  • Supplied in as-rolled or normalized condition

Applications of SAILMA High Tensile Plates

SAILMA steel plates are used across critical high-load industries, including:

  • Infrastructure projects: bridges, metro pillars, highway girders
  • Heavy equipment: dumpers, backhoes, cranes, earthmoving frames
  • Railway & defense: bogies, armored carriers, ballistic platforms
  • Structural steel fabrication: towers, pipe racks, platforms
  • Export-based fabrication yards: Middle East & African infra builds

Because of their lighter weight for same strength, they help reduce material cost and structural dead load.

Mechanical Properties of SAILMA 410 / 450 / 550 / 650 Plates

Grade Yield Strength (MPa) UTS (MPa) Elongation (%) Test Condition
E410 ≥ 410 520–650 ≥ 22 As-rolled / Normalized
E450 ≥ 450 570–720 ≥ 20 As-rolled / Normalized
E550 ≥ 550 630–780 ≥ 18 Normalized
E650 ≥ 650 700–850 ≥ 16 Normalized / QT
  • CE (Carbon Equivalent): Low for excellent weldability
  • Thickness Impact: Higher grades available up to 50 mm; beyond that on request

Indian Standards & Equivalent Grades for SAILMA Plates

SAILMA grades are developed and certified by Steel Authority of India (SAIL) and conform to Indian and international equivalents:

SAILMA Grade Indian Standard Global Equivalent

Heat Treatment & Toughness of SAILMA Grades

  • E410/E450: Typically supplied in as-rolled or normalized condition
  • E550/E650: Supplied in normalized or quenched & tempered (QT) form
  • Excellent impact toughness at sub-zero temperatures (Charpy tested variants available)
  • Heat-treated plates show enhanced grain refinement, better formability and higher tensile strength

Every batch can be supplied with impact test reports at -20°C or -40°C as required.

Weldability, Machinability & Fabrication Guideline

SAILMA grades are engineered for seamless fabrication:

  • Welding: Excellent; CE ≤ 0.45%; suitable for MIG, TIG, SMAW
  • Machining: Smooth surface finish; compatible with CNC, lathe, and boring
  • Bending/Forming: Can be cold bent up to 3× plate thickness
  • Post-weld heat treatment (PWHT): Not required for most fabrication jobs under 50 mm

We offer pre-welded trial coupons and WPS support for critical welding jobs.
