Description of the grade
SA387 GR.5 Class 1/2 PLATES are high-performance alloy steel plates that include molybdenum and chromium as the main content. In addition to these are alloyed with other content such as manganese, nickel, and silicon. The addition of molybdenum content offers superior tensile strength and whereas the chromium content offers superior resistance to corrosion and oxidation at elevated temperatures. The plates are high-quality molybdenum –chromium content steel plates that are extensively applicable in weldable carbon steel pressure vessels at high-temperature situations.

The plates perform well in high-temperature situations. Thus these are resistant to crevice and stress cracking corrosion. The addition of other content makes the plates heat tolerant, stronger and harder. Moreover, these plates are highly durable and versatile. Due to the annealing and normalizing process, the plates get rock hard surfaces. While utilizing the annealing process the surface of plates easily gets toughens with the removal of interior stress. The plates exhibit outstanding formability and anti-corrosion attributes. The plates are marvelously malleable and possess excellent weldability.

Material testing and quality inspections of product
