Features of A387 gr.11 boiler and pressure vessel steel plate:

The Molybdenum component in A387 gr.11 boiler and pressure vessel steel plate increases the plate tensile strength at high temperatures, and it also provides high resistance against oxidation and corrosion by increasing the lattice strain of the steel structure. That effectively stops the corrosive agents from dissolving the iron out of the steel structure.A387 gr.11 boiler and pressure vessel steel plate is good option for heat-resistant pressure vessels and sour gas environments.

 

Application of A387 gr.11 boiler and pressure vessel steel plate:

A387 gr.11 boiler and pressure vessel steel plate is popular used by power plant and dignity health medical foundation oil and gas industries in the production facilities because of the alloy's key properties.
