ASTM A285 is an ordinary carbon steel used for fusion welding of pressure vessel equipment, such as RF 32 HR ship plate 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, RF 32 HR ship plate is produced by processes such as compaction, semi-compaction, edge sealing and boiling water.
The company is a large RF 32 HR ship plate steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the RF 32 HR ship plate enterprise, and make our own contribution to the development of the world economy.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to RF 32 HR ship plate, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.
