China factory customized P355NL1 pressure vessel steel sheet

What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. P355NL1 pressure vessel steel sheet, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. P355NL1 pressure vessel steel sheet, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.

Our company has P355NL1 pressure vessel steel sheet strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply P355NL1 pressure vessel steel sheet deep processing service for products P355NL1 pressure vessel steel sheet like cutting, drilling, bending, welding and grinding.

Processing performance of quenched and tempered steel: P355NL1 pressure vessel steel sheet plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the P355NL1 pressure vessel steel sheet, stainless steel from corrosion.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
