EN-10028-2 Chrome Moly Steels
The European steel standard well known for pressure vessel purposes is EN 10028-2 which includes chrome moly plates.
The overall designation of the standard is "flat products made of steels for pressure purposes.
Non-alloy and alloy steels with detailed improved temperature properties.
Chrome moly material grades with various portions of chromium and molybdenum.
Extensively equal to the ones inside the American standard ASME SA387 and ASTM A387
EN 10028-2 chrome moly plate.
Champak Industries supplies chrome moly plates to EN 10028-2, 16MO3 PLATE, 13CRMO45 PLATES, 10CRMO910 PLATES and, when required by our customers, can offer cut to size plates and profiles to meet exact requirements.
The tables below give records referring to the chrome moly grades that are to be had Champak Industries.
