SA 387 GR.2 CL.1/2 Plates

Description of SA387 GR.2 Class 1/2 Plates

SA387 GR.2 Class 1/2 Plates are high-quality chrome-moly alloy steel plates designed for use in pressure vessels and industrial boilers. These plates are primarily alloyed with chromium and molybdenum, which contribute to their exceptional ability to withstand high temperatures and corrosive environments. This composition enhances their mechanical performance and ensures long-lasting durability.

The addition of molybdenum improves the plate's creep resistance and tensile strength, making it suitable for elevated temperature service. The presence of chromium enhances oxidation and corrosion resistance, offering reliable performance under harsh conditions. These properties make the plates particularly effective in extreme operating environments.

These SA 387 GR.2 alloy plates are commonly used in industries such as power generation, petrochemical, oil & gas, and chemical processing. Their superior thermal and structural integrity makes them a dependable choice for the manufacturing of weldable steel pressure vessels that operate under elevated temperatures and pressures.

EQUIVALENT GRADE OF A387 Grade 2 Class 1/2 Plate

The SA387 GR.2 Class 1/2 plates are specifically engineered for use in elevated temperature service in welded pressure vessels. They provide excellent creep resistance, oxidation resistance, and thermal stability, making them highly suitable for use in boilers, heat exchangers, and power plant components.

These plates undergo normalizing and tempering treatments to ensure an optimum balance of strength, ductility, and toughness. This thermal processing enhances their resistance to thermal fatigue and improves their mechanical performance. In addition to excellent formability and weldability, they offer long-term performance in critical pressure vessel applications operating at high temperatures.

Material Testing and Quality Inspections

The SA387 GR.2 Class 1/2 plates are thoroughly tested using a range of advanced techniques to guarantee compliance with stringent quality standards. The testing process includes mechanical property evaluation, PMI (Positive Material Identification), chemical composition analysis, intergranular corrosion (IGC) testing, hardness testing, and tensile strength testing. Further tests such as ultrasonic inspection, macro and micro tests, flattening and flaring tests, and pitting resistance analysis are also conducted to ensure product integrity and performance.
