China material S690QL1 datasheet professional supplier

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, material S690QL1 datasheet, etc.. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different for different grades.

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of material S690QL1 datasheet steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special material S690QL1 datasheet materials and specifications can be ordered in advance.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium material S690QL1 datasheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some material S690QL1 datasheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the material S690QL1 datasheet, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
