The delamination problem of S690QL plate thickness

26SiMnMo (GY5) is armored bulletproof steel, code-named GY4, with good ballistic performance, welding performance and mechanical processing performance. It is suitable for combat command vehicles, explosion-proof vehicles, currency transport vehicles, bulletproof trucks, bulletproof cars, explosion-proof doors, and machines. Need a safe and so on. According to the clients’ requirements, the steel plates with a thickness of more than 10mm can be subjected to ultrasonic inspection one by one, and the acceptance level should be indicated in the contract.

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 S690QL plate thickness 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 S690QL plate thickness materials and specifications can be ordered in advance.

Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled S690QL plate thickness plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy S690QL plate thickness steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.

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 S690QL plate thickness, 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.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
