EN10028-6 P500Q P500QH P500QL1 P500QL2 Pressure Vessel And Boiler Steel Plate

The designations P500Q, P500QH, P500QL1, and P500QL2 refer to different grades of weldable fine-grain steel plates specified in the EN10028-6 standard, primarily for pressure vessels and boilers. The differences lie in their heat treatment and specific mechanical properties, especially for low-temperature applications: P500Q is a standard high-strength steel, P500QH is a quenched and tempered version, and P500QL1 and P500QL2 are fine-grain grades suitable for low-temperature service, with QL1 and QL2 indicating different levels of impact energy at low temperatures.

P…Q means the -20 degree and the impact energy is 27J

P…QH means the -20 temperature quality and the impact energy is 27J
P…QL1 means the -40 temperature quality and the impact energy is 27J

P…QL2 means the -60 temperature quality and the impact energy is 27J

Thickness: 6MM to 300MM,

Width: 1500mm to 4050mm,

Length: 3000mm to 15000mm

EN10028-6 P500Q is a pressure vessel steel grade that is widely recognized for its exceptional properties and applications in the manufacturing of pressure equipment. This grade is part of the European standard for flat products for pressure equipment, and it is specifically designed to withstand high pressures and temperatures, making it suitable for critical applications in various industries.

EN10028-6 P500QH is a weldable fine-grain steel that is quenched and tempered, specified for use in pressure equipment like boilers and pressure vessels. The "P500" indicates a minimum yield strength of 500 MPa, the "Q" denotes it is quenched and tempered, and the "H" signifies it meets specific high-temperature requirements.

High strength P500QL1,P500QL1 steel plate,P500QL1 steel sheet,also named as boiler steel plate P500QL1,P500QL1 pressure vessel steel plate.because these steel plates are mianly used to built high temperature steel boilers and other pressure vessels.When rolling pressure vessel steel plate P500QL1,the low temperature impacting test shall be done at minus 40 centigree,Ultrasonis examination,heat treatment under quenched and tempered

P500QL2,P500QL2 steel plate,P500QL2 steel sheet which is under European specification EN 10028-6 standard.,all the steel materials covered by this standard shall be supplied in the quenched and tempered delivery condition.Pressure vessel steel plate P500QL2 belongs to the basic series steel which has to be done minus 60 centi degree low temperature impacting test,and boiler steel plate P500QL2 can be used under the much lower temperature working surroundings,such as deep oceans.

The primary applications of EN10028-6 P500Q, P500QH, P500QL1, and P500QL2 steel plates include:

· Pressure vessels

· Boilers

· Heat exchangers

· Storage tanks

· Columns and reactors in chemical and petrochemical plants

· Equipment for oil and gas industries

· Nuclear power plant components
