A pressure vessel grade steel for use in elevated temperature service, ASME SA387 Grade 11 Class 2 is used in a variety of industries and is highly effective, particularly in the oil, gas and petrochemical industry, where liquids and gases are often stored at higher temperatures The higher levels of chromium also provide excellent corrosion and oxidation resistance, which is a must in sour gas applications.

  • The ASME SA387 standards covers the supply of weldable chrome molybdenum alloy steel plates for pressure vessels used in elevated temperature service.
  • The added molybdenum and chromium provides excellent corrosion resistance and high temperature resistance respectively.

Heat Treatment Process Overview

Optimizing the heat treatment for SA387 Grade 11 steel plate involves carefully controlling the temperature, time, and cooling rate to achieve the desired mechanical properties and microstructure. SA387 Grade 11 is a chromium-molybdenum Alloy Steel used in the fabrication of industrial boilers and pressure vessels for elevated temperature service. Here are the key steps and considerations for optimizing the heat treatment process

The tubing and piping systems are multifunctional and operate at different pressures and temperatures, it is reasonable that the components involved are manufactured from different alloys using a range of fabrication techniques. Moreover, because the design conditions of different Boiler vary within a broad power-generating system, many different alloys will be used in various product forms. The materials used and the associated product quality checks are covered by applicable specifications and standards. However, it is frequently necessary for utility engineers to have access to basic metallurgical information to aid decision making for specific projects. Maintaining accurate knowledge of the full range of Boiler materials is becoming an increasing challenge for two

main reasons: the information base continues to grow even for wellestablished alloys, and new alloys—many with complex metallurgy—are being introduced.

Heat Treatment Objectives

  • Improve toughness: Enhance the toughness of the steel to prevent brittle failure.
  • Increase hardness: Achieve a balance between hardness and toughness
  • Enhance mechanical properties: Improve tensile strength, yield strength, and elongation.

Heat Treatment Processes


Normalizing is performed to refine the grain size and improve the uniformity of the microstructure.

  • Temperature: 900-950°C (1650-1740°F)
  • Cooling: Air cooling

Austenitizing is done to transform the steel's microstructure to austenite, which is necessary for subsequent treatments.

  • Temperature: 870-930°C (1600-1700°F)
  • Soaking Time: Sufficient to allow the entire section to reach a uniform temperature

Quenching is performed to increase hardness and Strength. However, rapid cooling can cause thermal stresses and distortions.

  • Medium: Oil or water (oil is preferred for slower cooling rates)
  • Cooling Rate: Controlled to avoid cracking and excessive residual stresses

Tempering is done to reduce brittleness and increase toughness by reducing residual stresses from quenching.

  • Temperature: 650-750°C (1200-1380°F)
  • Cooling: Air cooling
  • Time: 1-2 hours, depending on the thickness and desired properties

Practical Tips

Preheating Preheat the Aluminium Plates before austenitizing to minimize thermal shock and Post-Quench Inspection Inspect for cracks and distortions immediately after quenching and Record Keeping Maintain detailed records of heat treatment cycles for quality control and traceability.

ASME SA387 Specification

The ASME SA387 standard covers the supply of weldable chrome molybdenum alloy steel plates for Pressure Vessel used in elevated temperature service and The added molybdenum and chromium provides excellent corrosion resistance and high temperature resistance respectively and ASME SA387 standard plates are used by the world’s leading fabricators who in turn, supply primarily to the oil and petrochemical industry and Sourced from some of Western Europe’s & India's finest steel mills, Prosaic Steel and Alloys stock a wide range of ASME SA387 Class 2 plates and SA 387 GR11 which are available for shipment worldwide.

Testing and Validation

Mechanical Testing Perform tensile tests, hardness tests, and impact tests to validate the mechanical properties and Microstructural Analysis Use optical microscopy and scanning electron microscopy (SEM) to examine the microstructure and Non-Destructive Testing (NDT) Use ultrasonic testing (UT), radiographic testing (RT), or magnetic particle testing (MPT) to detect internal and surface defects.
