What is the effect of surface treatment on performance of s355j2 density

The development s355j2 density of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with s355j2 density high-quality and efficient services, work together for win-win, and create a better tomorrow!

ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as s355j2 density. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.

We have full ranges of gas cylinder steels, not only GB standard gas cylinder steel, but also JIG standard and EN standard materials. Such as SG255, SG295, HP265, P245NB, etc. The MOQ is 200 tons. For the gas cylinder steel coil, we can do s355j2 density further processing in our processing center and provide you gas cylinder steel plates. And we can punch steel discs for your convenient use.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, s355j2 density, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

13CrMo4-5 seamless pipe is a kind of pressure resistant seamless pipe in accordance with the European standard EN 10216-2. The chemical composition of 13CrMo4-5 seamless pipe is C 0.10-0.17, Si ≤ 0.35, Mn 0.40-0.70, P ≤ 0.025, S ≤ 0.020, Cr 0.70-1.15, Ni ≤ 0.30, Mo 0.40-0.60, Al ≤ 0.04, Cu ≤ 0.03. Mechanical properties of 13CrMo4-5 seamless pipe: tensile strength: 440-590 MPa, yield strength: ≥ 290 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. s355j2 density, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our s355j2 density products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

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.
