What Are SA 387 Gr.22 Cl.2 Plates and Why Do Refineries & Power Plants Rely on Them?

SA 387 Grade 22 Class 2 is a Cr-Mo (Chrome-Moly) alloy steel plate, engineered under ASTM A387 / ASME SA 387 standards. Known for high temperature resistance, creep strength, and oxidation protection, these plates are vital for:

  • Boiler & pressure vessel manufacturing
  • Refinery heaters & petrochemical equipment
  • Thermal & nuclear power generation
  • Storage tanks & heavy process equipment

In short: SA 387 Gr.22 Cl.2 plates are the backbone of safe high-temperature operations worldwide.

The Hidden Risks Buyers Face While Procuring SA 387 Gr.22 Cl.2 Alloy Steel Plates

Every procurement manager and project engineer knows the risks:

  • Wrong grade supplied (Cl.1 instead of Cl.2 → outright rejection at site)
  • Delayed supply during shutdown projects → penalties & downtime
  • Lack of certifications (IBR, PED, EN 10204) → non-compliance in EPC contracts
  • Hidden costs in freight, insurance, and export packing
  •  Mill delays without buffer stock → project disruption

At Navgraha Steels INC, we remove these risks by maintaining ready Mumbai stock, global mill tie-ups, and export-proven documentation – ensuring buyers receive the right plate, on time, every time.

Applications of SA 387 Gr.22 Cl.2 Plates Across Key Industries

Our plates are trusted in mission-critical industries where failure is not an option:

  •  Boilers & Superheaters – maintaining strength at 500–600°C
  • Refineries & Petrochemical Plants – heaters, pressure vessels, exchangers
  • Thermal & Nuclear Power Plants – creep-resistant under extreme cycles
  • EPC & Process Projects – turnkey fabrication, storage tanks, industrial vessels

Wherever high heat meets high pressure, SA 387 Gr.22 Cl.2 plates are the engineer’s material of choice.

Mechanical Properties of SA 387 Gr.22 Cl.2 Chrome Moly Plates

These plates are designed for strength, creep resistance, and weldability at elevated temperatures:

  • Yield Strength: 275 – 345 MPa
  • Tensile Strength: 485 – 620 MPa
  • Elongation: 18 – 22% (excellent for fabrication & forming)
  • Impact Strength: Stable even at elevated service conditions
  • Brinell Hardness: 170 – 220 HB

Buyer Advantage: Longer service life, lower downtime, and assured safety in high-temperature pressure systems.

Chemical Composition of ASTM A387 Gr.22 Cl.2 Plates

The Cr-Mo chemistry gives these plates superior creep strength & oxidation resistance:

Element Content (%)
Carbon (C) 0.05 – 0.20
Manganese (Mn) 0.30 – 0.60
Silicon (Si) 0.50 – 1.00
Chromium (Cr) 1.90 – 2.60
Molybdenum (Mo) 0.87 – 1.13
Phosphorus (P) ≤ 0.035
Sulphur (S) ≤ 0.035

Buyer Advantage: Higher Chromium (2.25%) for scaling resistance + Molybdenum (1%) for creep resistance → reliability in refineries & power plants.
