SA 387 GR.22 CL.1/2 PLATES are molybdenum-chromium alloy steel plates furthermore it includes manganese and silicon content. The plates found its application in weldable carbon steel stress vessels at soaring temperatures. The presence of chromium content offers superior corrosion resistance whereas molybdenum content provides excellent tensile strength at elevated temperatures. These grade of plates posses superior durability and ensures excellent stress distribution. Due to the annealing and normalizing process these plates get rock hard surfaces. Whereas the annealing ensures to toughens the surface by reducing the internal stress. The plates are superior malleable plates that offer outstanding formability and rust proof finish.
Thus these are supplied in tempered and normalized circumstances. The SA 387 GR.22 CL.1/2 PLATES exhibits high heat resistance and exceptionally useful in those applications where hot gases and solutions are being processed at elevated temperatures. These plates require exceptional weldability, thus these are readily welded to form superstructures. Due to the brawny surface of plates these does not get crack and deform through sudden fluctuations and shocks. Even more, these grade of plates are capable of reduction corrosive films on its surface and demonstrate resistance to pitting, sulfide, crevice and stress corrosion cracking. The plates sustain superb hardness and dimensional accuracy. Furthermore, it also provides excellent resistance to oxidation by increasing the lattice strain of the steel structure. The plates perform excellently in elevated temperatures as it offers good properties both at soaring and low temperatures.
