What Are SA 387 Gr.12 Cl.2 Alloy Steel Plates and Why Do Refineries & Power Projects Depend on Them?

SA 387 Grade 12 Class 2 is a Chrome-Moly alloy steel plate, specifically developed for elevated temperature and pressure service. In Cl.2 condition (Normalized + Tempered), these plates provide:

  • High tensile strength & toughness under thermal cycling
  • Oxidation resistance at elevated temperatures
  • Excellent creep resistance for long-term high-pressure use
  • Conformance to ASME/ASTM boiler & pressure vessel standards

This makes SA 387 Gr.12 Cl.2 plates the material of choice for boilers, pressure vessels, and refinery reactors, where safety, durability, and compliance are non-negotiable.

Procurement Risks Buyers Face While Sourcing SA 387 Gr.12 Cl.2 Plates

If you’re a procurement manager or EPC project head, you’ve likely faced these challenges:

  •  Wrong grade/class supplied → causes material rejection and costly rework
  •  Missing IBR / PED / EN 10204 certification → non-compliance penalties
  •  Delivery delays → shutdown fines and lost contracts
  •  Inferior packaging → rust, edge damage, or rejection at customs
  •  Non-transparent pricing → hidden charges post-order

At Navgraha Steels INC, we solve these issues by ensuring:

  •  Strict grade verification & mill test certification (MTCs)
  •  IBR, PED, EN 10204 3.1/3.2, CE approvals
  •  Ready stock in Mumbai + mill allocations for large projects
  •  Seaworthy packaging with rust prevention
  •  Clear CIF/FOB pricing, no hidden costs

Applications of SA 387 Gr.12 Cl.2 Plates Across Global Industries

Our plates are engineered for industries where heat, pressure, and compliance converge:

  • Boilers & Heat Exchangers – consistent strength under thermal load
  • Refineries & Petrochemical Plants – safe handling of corrosive media
  • Power Generation (Thermal & Gas Plants) – long-term creep resistance
  •  Pressure Vessels & Reactors – compliance with ASME Section VIII codes
  • EPC & Shutdown Projects – urgent deliveries for time-sensitive repairs

Wherever projects demand reliability under heat and pressure, SA 387 Gr.12 Cl.2 plates deliver the peace of mind buyers need.

Mechanical Properties of SA 387 Gr.12 Cl.2 Alloy Steel Plates
