What tests need to go through in the S355J2W weather resistant steel production process

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing S355J2W weather resistant steel high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

These grades A709 Grade 36, S355J2W weather resistant steel, A709 Grade 50 and A709 Grade 50W are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, which is a per-plate test (Frequency "P"). Bridge steels can be ordered with plate thickness up to 150mm.

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 S355J2W weather resistant steel 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.

Alloy steel plate is formed by adding alloy elements into steel. In this process, the basic elements of steel, namely iron and carbon, will have a certain effect with the newly added alloy elements. Under this effect, the structure and material in the steel will have certain changes, and the overall performance and quality of steel will also be improved. Therefore, the output of S355J2W weather resistant steel, alloy steel plate is increasing, and its application range is more and more extensive.

10CrMo9-10 seamless pipe implements European standard EN 10216-2. The chemical composition of 10CrMo9-10 seamless pipe: C 0.08-0.14, Si ≤ 0.50, Mn 0.30-0.70, P ≤ 0.025, S ≤ 0.020, Cr 2.00-2.50, Ni ≤ 0.30, Mo 0.90-1.10, Al ≤ 0.04, Cu ≤ 0.03. The mechanical properties of 10CrMo9-10 seamless pipe: tensile strength: 450-530 MPa, yield strength: ≥ 280 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. S355J2W weather resistant steel, 10CrMo9-10 seamless pipe is a kind of high temperature and high pressure boiler steel, which is mainly used in the production of power station boiler, steam boiler equipment, pressure vessel, large pressure pipe, etc.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the S355J2W weather resistant steel, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.

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.
