S690QL1 specification container plate

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 S690QL1 specification 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.

The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of S690QL1 specification, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.

we also provide the S690QL1 specification welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful S690QL1 specification welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S690QL1 specification products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
