Boiler Steel Plates for Steam Boilers

Introduction to Steam Boiler Plates

Boiler steel plates are the backbone of steam boiler fabrication, providing the required strength, durability, and corrosion resistance to withstand high pressure and elevated temperatures. At Hindustan Steel Corporation, we supply boiler plates specifically tested and certified for use in steam generation systems—from small package boilers to large utility boilers in power plants.

Why Are Special Plates Needed for Steam Boilers?

Steam boilers involve extreme temperature and pressure fluctuations. Using generic plates can lead to cracking, deformation, or failure. Our boiler-quality plates are engineered for:

  • High-temperature creep resistance
  • Pressure containment without distortion
  • Resistance to hydrogen attack and acidic corrosion

Industrial Sectors Using Steam Boiler Plates

Boiler plates are in demand across:

  1. Thermal and captive power plants
  2. Sugar, textile, and paper mills
  3. Refinery and petrochemical boilers
  4. Industrial heating systems
  5. Biomass and waste heat recovery units

Mechanical Properties of Boiler-Grade Plates

Typical properties include:

  • Yield Strength: 240–355 MPa
  • Tensile Strength: 470–650 MPa
  • Elongation: 22% minimum
  • Impact tested at -20°C or -46°C depending on grade

Best Plate Grades for Steam Boilers

We offer plates in grades including:

  • ASTM A516 Grade 60 / 70
  • DIN 17155 HII / 17Mn4
  • EN 10028 P265GH / P295GH / P355GH / P355NH
  • IS 2002 Grade 1 / 2 / 3 (Indian standard)
  • ASME SA516 / SA387 for pressure retention

Standard Thickness & Width Options

Our boiler plates are available in:

  • Thickness: 6 mm to 150 mm
  • Width: 1250 mm to 3000 mm
  • Length: Up to 12,000 mm
  • Custom sizes available with edge prep and CNC cutting

Heat Treatment for High-Temperature Use

Plates are supplied in:

  • Normalized condition (N) for stress resistance
  • As-rolled (AR) for cost-effective options
  • Quenched and Tempered (Q+T) for high-strength applications

Weldability and Formability

Boiler plates from HSC offer:

  • Excellent weldability using TIG/MIG/SMAW
  • Low carbon content to reduce HAZ cracking
  • Bend-tested and flattening-tested for critical forming

Why Choose Hindustan Steel for Steam Boiler Projects

  • IBR-approved and PED-certified material
  • Large in-stock inventory for urgent shutdowns
  • Technical support for plate selection and code compliance
  • Cut-to-size supply with MTC & Third Party Inspection on request

Popular Boiler Plate Grades Supplied

  • A516 Gr 70 (most requested in steam boilers)
  • P265GH and P355NH (common in Europe & GCC)
  • DIN 17155 HII (used in German-origin boilers)
  • IS 2002 (legacy Indian boilers)

Global Supply Footprint for Boiler Fabricators

We export steam boiler plates to:

  • UAE, Saudi Arabia, Oman
  • Vietnam, Philippines, Indonesia
  • South Africa, Egypt, Kenya
  • Bangladesh, Sri Lanka, Nepal

Tips for Selecting the Right Boiler Plate

  • Match pressure class and temperature rating
  • Ask for impact-tested plates if working in sub-zero zones
  • Ensure compatibility with design code (ASME, EN, IBR, etc.)
  • Consider HIC/NACE plates for acidic steam systems

Certifications for Steam Boiler Use

All boiler plates come with:

  • IBR Form III or IIIC
  • EN 10204 3.1 / 3.2
  • Lloyds / TUV / DNV / ABS (on request)
  • Ultrasonic, impact, flattening, and tensile test reports

Cut-to-Size Boiler Plates – Reduce Wastage

We provide:

  • Sheared or mill edges
  • Profile-cut shells, end caps, circles
  • Nesting optimization for project cost saving
