Decision factors of S690QL australian equivalent performance

ASME SA 53 seamless pipe is a low carbon S690QL australian equivalent steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized S690QL australian equivalent steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of S690QL australian equivalent circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and S690QL australian equivalent management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the S690QL australian equivalent rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of S690QL australian equivalent steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of S690QL australian equivalent, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
