What Are SA 387 Gr.11 Cl.2 Sheets and Why Do Global Projects Depend on Them?

SA 387 Grade 11 Class 2 is an alloy steel (Chrome-Moly) sheet specified under ASTM A387 / ASME SA 387 standards. These sheets are designed for elevated temperature service in industries where safety and compliance are non-negotiable.

Key reasons buyers choose this grade:

  • High creep resistance at elevated temperatures
  • Excellent weldability with PWHT compatibility
  • Durability under extreme heat cycles
  • IBR/PED approved for global boiler & pressure vessel use

In short: these sheets are the foundation of reliable high-temperature equipment.

The Pain Points Buyers Face When Sourcing SA 387 Gr.11 Cl.2 Alloy Steel Sheets

Procurement teams often struggle with:

  • Grade mismatch (Cl.1 supplied instead of Cl.2)
  • Lack of certification (no EN 10204 3.1/3.2, IBR, or PED approvals)
  •  Unreliable stock in critical thicknesses (8mm–20mm)
  • Late deliveries during refinery or power plant shutdowns
  • Hidden costs in cutting, machining, or export packing

At Navgraha Steels INC, we solve these challenges with ready Mumbai stock, certified documentation, transparent pricing, and on-time global dispatch.

Applications of SA 387 Gr.11 Cl.2 Sheets in Boilers, Refineries & Power Plants

SA 387 Gr.11 Cl.2 Sheets are trusted across industries that demand strength + heat resistance:

  •  Boilers & Superheaters – reliable in high-pressure steam environments
  • Refinery Heaters & Vessels – ideal for petrochemical exposure
  • Thermal & Nuclear Power Plants – withstanding 500–600°C conditions
  • EPC & Process Industry Projects – pressure vessels, exchangers, storage tanks

Wherever failure is not an option, SA 387 Gr.11 Cl.2 sheets deliver proven safety and long service life.

Mechanical Properties of SA 387 Gr.11 Cl.2 Sheets That Ensure Performance

SA 387 Gr.11 Cl.2 sheets combine strength, ductility, and heat resistance for demanding boiler and pressure applications:

  1. Yield Strength: 240 – 310 MPa
  2. Tensile Strength: 415 – 585 MPa
  3. Elongation: 18–22% (excellent ductility for forming & welding)
  4. Impact Strength: Reliable at elevated service temperatures
  5. Hardness (Brinell): 170 – 220 HB

Buyer benefit: Ensures long life, safe operation, and reduced risk of failure under high temperature and pressure.

Chemical Composition of ASTM A387 Gr.11 Cl.2 Alloy Steel Sheets

The controlled chemistry provides creep resistance and oxidation stability:

Element Content (%)
Carbon (C) 0.05 – 0.20
Manganese (Mn) 0.30 – 0.60
Silicon (Si) 0.50 – 1.00
Chromium (Cr) 1.00 – 1.50
Molybdenum (Mo) 0.45 – 0.65
Phosphorus (P) ≤ 0.035
Sulphur (S) ≤ 0.035

Buyer benefit: Chromium improves oxidation resistance, while Molybdenum delivers creep strength — exactly what refineries and power plants demand.

Standards, Certifications & Equivalent Grades of SA 387 Gr.11 Cl.2 Sheets
