What is PVQ A387 grade 11 class 2 boiler steel plate carbon content

PVQ A387 grade 11 class 2 boiler steel plate,The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the industry, keep pace with the times, and move towards a new course!

PVQ A387 grade 11 class 2 boiler steel plate,The commonly PVQ A387 grade 11 class 2 boiler steel plate steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main PVQ A387 grade 11 class 2 boiler steel plate boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, Q345R, A204 grade B, A285C, ASTM A387, P355GH and so on.

20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than , No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as PVQ A387 grade 11 class 2 boiler steel plate, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.

PVQ A387 grade 11 class 2 boiler steel plate,we also provide the welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

The requirements for toughness impact energy of S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.
S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27J
S355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27J
As the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
