Principle of surface pretreatment of S690QL young's modulus

BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, S690QL young's modulus steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, S690QL young's modulus chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

Heat-resistant steel has good oxidation resistance, corrosion resistance and tissue stability. The thermal strength performance is high, and the S690QL young's modulus process performance is good. Heat-resistant steel plates and sheets are commonly used in the manufacture of parts that work at high temperatures in industrial sectors such as boilers, steam turbines, power machinery, industrial furnaces, and aviation and petrochemical industries.

Bridge steel S690QL young's modulus is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S690QL young's modulus nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S690QL young's modulus steel, can be used as an alloying element of low alloy steel.

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. S690QL young's modulus, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than S690QL young's modulus 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
