EN steel grade S450J0 material for pressure vessels

The carbon content of EN steel grade S450J0 material carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel EN steel grade S450J0 material can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.

The company specializes in the research and development, production and sales of EN steel grade S450J0 material seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has EN steel grade S450J0 material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,EN steel grade S450J0 material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Steel plate EN steel grade S450J0 material cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick EN steel grade S450J0 material steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.

The effect of elements in EN steel grade S450J0 material, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
