Boiler Steel Plates – What Are They?
Boiler steel plates are specialized pressure vessel-grade steel plates designed to withstand high pressure and temperature conditions. These plates are manufactured using carbon steel or alloy steel and comply with international standards like ASTM A516, ASME SA516, EN 10028, and DIN 17155.
Why Are They Used in Boilers?
Because they offer:
- High-temperature resistance
- Superior weldability
- Excellent toughness & ductility
They form the core structure of steam boilers, heat exchangers, and pressure vessels that operate under harsh industrial environments..
Key Properties of Boiler Plates
- Pressure resistance: up to 6000 psi depending on grade
- Temperature handling: up to 600°C
- Compliance: ASME, IBR, NACE, PED
Grades Commonly Used in Boilers
- ASTM A516 Gr 60/70
- SA387 Gr 11 / Gr 22 (Chrome Moly)
- EN 10028 P265GH, P355NH
- DIN 17155 HII / 17Mn4
- HIC/NACE tested variants for acid service
Power Plants (Steam & Thermal)
Boiler plates are essential in:
- Boiler drums, headers, and steam lines
- Superheaters and economizers
Grades like A516 Gr 70 and SA387 are used due to high-pressure resistance
Oil Refineries & Petrochemical Units
Used for:
- Distillation columns and pressure vessels
- Reactors and separators
Especially when NACE/HIC-resistant steel is required to avoid acid cracking.
Chemical Processing Equipment
Plates like P265GH and 17Mn4 are used for:
- Heat exchangers
- Storage tanks for acids, ammonia, and solvents
Fertilizer & Gas Processing Plants
Applications include:
- Urea towers, CO₂ scrubbers, flash drums
- Use of chrome-moly plates for corrosion and pressure resistance
Shipbuilding & Marine Boilers
Boiler-grade plates are used for onboard:
- Steam generators
- Hot oil systems
Preferred grades: DIN 17155 HII, A516 Gr 60
Food & Beverage Industry
In breweries and dairy processing, they’re used in:
Sterilizers, heat exchangers, pressure cookers
Hygienic-grade boiler plates meet PED and ISO standards
