By Standards & Specifications (ASTM, ASME, Alloy Steel)

SA 387 Gr.11 Cl.2 belongs to the ASTM A387 / ASME SA387 Chrome-Moly Steel family:

  • ASTM A387 Grade 11 Class 2 → Alloy steel for high-temperature pressure vessels.
  • ASME SA387 Gr.11 Cl.2 → Boiler and pressure vessel applications.
  • Equivalent Grades → EN 10028 13CrMo4-5 (Europe), BS 1501-621B (UK).

It offers superior performance at elevated temperatures (up to 600°C), making it suitable for boilers, refineries, and petrochemical industries.

By Brand / Mill Origin – Indian & Global Mills

At Navgraha Steels INC, we supply SA 387 Gr.11 Cl.2 plates, sheets & coils from:

  • Indian Mills → Sail, AMNS, JSPL, Evonith
  • Global Mills → Nippon Yakin (Japan), Outokumpu (Finland), VDM (Germany), ATI (USA)

Indian mills ensure competitive pricing, while global OEM mills are preferred for EPC contracts requiring EN/CE-certified supply.

By Testing & Quality Control – Boiler & Pressure Vessel Standards

SA 387 Gr.11 Cl.2 is subjected to rigorous testing:

  1. Tensile, Yield & Elongation Testing → Mechanical strength validation.
  2. Impact Testing (Charpy V-Notch) → Ensures toughness at elevated temperatures.
  3. Hardness Testing (BHN) → Boiler-grade consistency.
  4. Ultrasonic Testing (UT 100%) → Detects internal defects.
  5. Third Party Inspection (TPI) → Lloyd’s, TÜV, BV, SGS available.

EPC and refinery buyers demand EN 10204 3.1/3.2 MTCs with full traceability for project approvals.

By Manufacturing & Finish – HR, Normalized, Annealed

  1. Hot Rolled (HR) Plates → Standard supply for boilers & pressure vessels.
  2. Normalized (N) → For improved creep resistance.
  3. Annealed → For machinability & fabrication ease.
  4. Pickled & Oiled (P&O) → For coil supply.

Refineries often demand normalized plates to withstand high-temperature service.

By Thickness, Width & Supply Form

  • Plates: 6mm – 150mm thick, up to 3000mm width, 12m length.
  • Sheets: 3mm – 12mm thickness, standard & cut-to-size.
  • Coils: 2mm – 20mm, widths 1000–2000mm.

Customized cutting, beveling, and edge preparation available for pressure vessel fabrication.

Industry Applications – Where SA 387 Gr.11 Cl.2 is Used

This grade is widely chosen for high-temperature and pressure applications:

  • Boilers & Steam Drums
  • Pressure Vessels & Heat Exchangers
  • Refineries & Petrochemical Units
  • Thermal Power Plants
  • Oil & Gas Processing Units
  • Chemical Reactors & Storage Tanks

Preferred by EPC contractors due to its long-term creep resistance and weldability.

How to Source SA 387 Gr.11 Cl.2 at Best Price

Procurement teams must focus on these essentials:

  1.  Check Mill Origin – Indian mills for cost efficiency; Global OEM mills for EPC-approved supply.
  2.  Confirm Heat Treatment – Normalized/annealed condition is critical for boiler-grade use.
  3.  Verify Testing – UT 100%, hardness, impact, and creep tests are mandatory for pressure service.
  4.  Insist on MTCs – EN 10204 3.1/3.2 MTCs with chemical + mechanical details.
  5.  Cut-to-Size Option – Reduces welding joints & saves fabrication costs.

Choosing the right supply reduces rejection risk & ensures EPC project approvals.
