1/8 S690Q vs S690QL 4x8 factory near me

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, S690Q vs S690QL quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the S690Q vs S690QL International leading steel materials supplier.

15Mo3 steel is a kind of pearlitic heat-resistant steel, which can still show its characteristics under high temperature and long time load. 15Mo3 steel is used for heating surface of S690Q vs S690QL low and medium pressure boiler (working pressure is generally not more than 5.88MPA, and working temperature is below 450 ℃). 15Mo3 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. 15Mo3 steel is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, etc.

Strong pressure resistance of S690Q vs S690QL, 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.

The purpose of S690Q vs S690QL quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of S690Q vs S690QL. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
