EN 10028-2 Chrome Moly Plate

Plate for pressure vessel purposes.
More information about the EN 10028-2 standard:

• The full designation of the standard is “Flat products made of steels for pressure purposes”.
• The standard covers non-alloy and alloy steels with specified elevated temperature properties.
• Also covered are chrome moly material grades with varying quantities of chromium and molybdenum.
• EN 10028-2 steels found in the table below, such as 16Mo3 are broadly equivalent to those in the American standards ASME SA387 and ASTM A387.
