ASTM A387
ASTM A387 is the technical delivery standard covering the supply of chrome molybdenum pressure vessel alloy steel plates.
The introduction of chrome molybdenum increases the materials temperature tensile strength making it an excellent choice for elevated temperature environments. The material also displays excellent corrosion resistant characteristics. ASTM A387 is therefore ideal for the fabrication of weldable steel pressure vessels and industrial boilers found commonly in the petrochemical and oil industry.
CHEMTECH ALLOYS PVT LTD stocks an extensive range of ASTM A387 Class 2 plates, which are available for shipping worldwide. Our plates are pre-tested to stringent standards which means in many cases we are able to ship to you immediately. Should you have more specific testing requirements we can arrange third party testing for you. Even in the event that a particular grade is not currently in stock, we can arrange shipping to you directly from the mill itself.
A387 Grade 12 Class 2 is a high quality chrome molybdenum steel which is ideal for elevated temperature service and offers excellent anti corrosion characteristics.
The steel has a wide range of uses including industrial boilers and pressure vessels, especially in environments where high temperature levels are common.
