16Mo3 Steel Plates and Pipes for Power Plant Piping

In 25th September 2015, Hebei Metals Industrial Limited received a large order from BULMFELD, who is a German contracting company dedicating to power-station solution in Europe. The order is for a power plant project in Czech Republic. Considering the high temperature conditions, 16Mo3 / 1.5415 as well as its ASTM equivalent(ASTM A335 Gr.P1 / ASTM A204 Gr.A and Gr.B) are specifed to meet the European design code. The 16Mo3 steel plate manufactured to EN 10028-2 is required for prefabrication of the pressure vessel while 16Mo3 steel pipes(seamless) made to EN 10216-2 are required for the heat-exchanger piping.
