stal S460Q 300 Tons

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, stal S460Q based on a high starting point and high technology, the company has vigorously developed various steel products stal S460Q and deep-processed parts, steel structures, precision castings, seamless pipes.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of stal S460Q, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product stal S460Q more than 15 years.

As the thickness and hardness of stal S460Q increase, the tendency to crack at the cutting edge increases. In order to prevent the stal S460Q from cutting cracks, preheating should be carried out before stal S460Q cutting. Special attention should be paid to preheating to make the entire stal S460Q interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole stal S460Q cannot be preheated, the partial preheating method can be used instead.

A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. stal S460Q, A588 Grade Acould be produced in 200mm in our company.

We are willing to cooperate sincerely with you with high-quality stal S460Q products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
