The main component of PVQ P355NH boiler steel plate manganese plate is manganese, which is a relatively powerful element type, and plays a more important role in long-term development and continuous use. The main characteristics of manganese plates are high hardness and high strength. For general manganese plates, it is necessary to enhance the compressive capacity of manganese steel plates and various basic corrosion resistance capabilities. For common manganese plates, pay attention to use, choose good specifications and classifications, thus the use value of manganese plates will be better.
PVQ P355NH boiler steel plate,Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, are strict. In the chemical composition of boiler steel, , sulfur and phosphorus are strictly controlled Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties In addition, strain aging impact test is also required for boiler steel The quality control of boiler steel is slightly higher than that of pressure vessel steel,PVQ P355NH boiler steel plate.
PVQ P355NH boiler steel plate,Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials,PVQ P355NH boiler steel plate.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.PVQ P355NH boiler steel plate
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
