ASTM A285 is an ordinary carbon steel used for fusion welding of pressure vessel equipment, such as A572 grade 55 high strength steel boilers, storage tanks, heat exchangers, etc. The tensile strength of the three steel grades (Grade A, Grade B, and Grade C) ranges from 310-515Mpa, and ASTM A285 steel plates are usually delivered in the rolled state. According to user requirements, A572 grade 55 high strength steel is produced by processes such as compaction, semi-compaction, edge sealing and boiling water.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the A572 grade 55 high strength steel, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
