S690QL application material grade comparison

The production process of seamless steel pipe for high pressure boiler is more strict than that of S690QL application ordinary steel pipe. In the process of using seamless steel pipe for high pressure boiler, oxidation and corrosion will occur under the action of high temperature flue gas and steam. Therefore, the requirements for the durability and anti-oxidation corrosion performance of seamless steel pipes for high-pressure boilers are higher, and has requirements for good structural stability.

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product S690QL application structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel S690QL application supplier in the world.

WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders S690QL application WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, S690QL application.
