API2WGr60 material is a special material for pipeline steel. It is mainly used to transport large-diameter welded steel pipes such as oil and natural gas for hot-rolled coils or thick and wide plates. In addition to high compressive strength, it also requires high low temperature toughness and excellent welding performance. As a leading supplier of , API2WGr60 pipeline steel plate in China, our company supply API2WGr60 steel plate, API2WGr60 steel stock and API2WGr60 steel pipe with favourable price,A514 grade J alloy steel plate.
Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel A514 grade J alloy steel plate not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
In actual processing applications, the processing A514 grade J alloy steel plate thickness of flame cutting ranges from 6 to 200 mm, and the cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting A514 grade J alloy steel plate with a certain thickness above 10mm,A514 grade J alloy steel plate.
Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.A514 grade J alloy steel plate
