A387 Pressure Vessel Steel Plate

ASTM A387 Boiler vessel plates are chrome-molybdenum alloy steel plates suitable for welding boilers and high temperature pressure vessels.

PRODUCT DESCRIPTION

ASTM A387 boiler container plate is divided into grade 5, grade 9, grade 11, grade 12, grade 22, grade 91 and other grades according to the alloy elements contained. Except for grades 21L, 22L, 91 and 911, each grade of ASTM A387 boiler vessel plate has two tensile strength categories according to its heat treatment: Class 1 and Class 2. A387 is a chromium-molybdenum alloy steel plate for pressure vessels. It has good high-temperature strength, oxidation resistance and sulfide corrosion resistance. The working environment of this material is harsh, and the working medium is reaction products such as hydrogen, hydrogen sulfide, wax oil, gasoline, diesel, and thermal synthesis gas, as well as raw oil.

Scope of Application

The molybdenum composition in ASTM A387 boiler vessel plate can improve its tensile strength at high temperature, and make it have higher oxidation and corrosion resistance by increasing the lattice strain. ASTM A387 Boiler Container Plates are ideal for use in heat-resistant pressure vessels and sour gas environments.
