Decision factors of S460QL steel pipe performance

Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. S460QL steel pipe. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

Based on the main S460QL steel pipe business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel S460QL steel pipe products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The company has passed ISO quality management system certification, domestic advanced production technology, and high product batch stability. Selected materials, the source controls every quality link to ensure S460QL steel pipe product high quality. Use automated, scientific and systematic manufacturing processes to meet the different needs of customers. Become an excellent domestic steel plate manufacturer, serving customers all over the world.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, S460QL steel pipe, 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.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
