A387 grade 5 heat resistant plate Chrome Molybdenum plates are produced in a wide variety of grades across the world. Below we have listed some of the more common ones and their equivalents.

Equivalency is dependent on the chemical composition, the physical properties and the application that it will be used in. Consequently the table below is for information and guidance only.

The ASTM/ASME standards are functionally identical. EN10028 is the European standards covering chromium molybdenum low allow steel plate for pressure vessel uses and the DIN standards are the German standards. These have been superseded by the EU standard though the old names are still popular.

We haven’t included the British BS standard BS1501-161-430A/B which has also been superceded by EN10028. Generally steels produced to BS 1501-161-430A are normal pressure vessel steels and BS1501-161-430B are for steels required to perform at elevated temperatures and pressures. i.e. Chrome moly equivalent steels.

For the avoidance of doubt please check with our sales staff and your design engineers that an offered grade is suitable for your needs.
