China made PVQ A204 Gr B boiler steel plate properties

Our company's power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process,PVQ A204 Gr B boiler steel plate.

PVQ A204 Gr B boiler steel plate,S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The steel Grade S355NL making process shall according to EN10025-1.

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. The large-diameter thick wall steel pipes purchased by us are long or short. If they are short, they can be welded. If they are long, they need to remove the redundant parts, that is, cut them out. Their length is suitable for the length required by the construction of steel pipes.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness. EN10083-3 42CrMo4 steel plate has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.
