The S960QL mechanical properties price forecast this week in China

What are the characteristics of medium and thick plate, S960QL mechanical properties? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, S960QL mechanical properties is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the S960QL mechanical properties construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU S960QL mechanical properties steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in S960QL mechanical properties etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35, S960QL mechanical properties. On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).
