S690QL EN 10025-6 high strength steel carbon steel usages

Seamless steel tubes for high-pressure boilers are mainly used in pipes, headers, economizers, superheaters and heat exchangers of high-pressure boilers. The working pressure of seamless steel tubes for high-pressure boilers is generally above 9.8 MPa and the working temperature is between 450℃ and 650℃. The main grades of seamless steel tubes for high pressure boilers are 15CrMoG, 12CR2MOG, 12Cr1MoV, S690QL EN 10025-6 high strength steel, etc.. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different for different grades.

Our company was founded in 2000, which initially committed to providing high-quality steel S690QL EN 10025-6 high strength steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S690QL EN 10025-6 high strength steel steel to the international market, opening up the international steel market.

Cold rolled S690QL EN 10025-6 high strength steel steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner S690QL EN 10025-6 high strength steel steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as S690QL EN 10025-6 high strength steel.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
