In the market, the price of S690QL1 chemical composition, alloy coil plate is unstable. When purchasing alloy plate, first of all, you need to observe the market situation, and then do a price analysis. In this way, you can buy the most favorable alloy coil plate. At the same time, you can also go to the Internet to inquire about the manufacturer of alloy coil plate. It is necessary to consult the price and ask several manufacturers for comparison. For the S690QL1 chemical composition, alloy coil plate quality, you can visit the manufacturer to have a look at the material and quality. Finally, you can choose the most suitable manufacturer to put orders.

42CrMo alloy steel S690QL1 chemical composition: low temperature tempering welding performance thermal processing
The heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

Strong pressure resistance of S690QL1 chemical composition, boiler steel tube: The wall thickness of boiler steel tube is very important, because the steam pressure is very large, if the wall thickness is very thin, it will be broken by the steam pressure released instantly. The boiler steel tube has good high temperature resistance performance: the steam temperature in the pipeline can reach hundreds of degrees Celsius above. If the high temperature resistance performance is not enough, the boiler steel tube will be melted by the high temperature brought by the steam.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
