Comparison and application of Q345R steel and SA-516 steel

This aritical is about Comparison and application of Q345R steel and SA-516 steel. Design and application of pressure vessels in China Q345R steel plate is widely used in manufacturing, but SA-516 steel plate is mostly applied to pressure vessels designed and manufactured according to ASME specification. Q345R steel plate can be produced by many factory now. and katalor also can supply Q345R steel plate.

In recent years, equipment damage or rupture accidents are often caused by H2S in petrochemical industry. Many scholars have studied this problem. At the same time, steel with a certain ability to resist hydrogen-induced cracking (H-drogen Included Cracking, H-IC) is smelted out to make equipment used in wet H-2S environments. Domestic Q345R steel is one of them.

Compared with SA-516 steel, Q345R steel has strict chemical composition control and stable mechanical properties. Q345R steel is more suitable for manufacturing pressure vessels used in wet H 2S corrosion environment. With the continuous renewal and improvement of production conditions of china extra-thick Q345 steel plate, Q345R steel's quality has reached the level of similar products abroad, and Q345R steel plate can be applied to similar projects at home and abroad instead of imported materials.
