How will S890QL steel price go this week

We are a professional S890QL steel steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product S890QL steel quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

Steel material has an irreplaceable role in many projects, especially in building construction, bridge cofferdams, road construction, foundation pit support, garden engineering, excavator paving, subgrade engineering and other projects. Therefore, the quality of S890QL steel steel material can not be ignored, so how should customers identify the authenticity of steel when choosing steel materials? Today we would like to analyze it together. So that it can help you to purchase satisfied steel materials in the future.

S700MC high-strength cold-formed hot-rolled steel sheet S890QL steel more greatly improves the yield strength than traditional steel grades, and at the same time has good elongation performance, cold bending performance, welding performance and impact resistance. S700MC high-strength steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large-scale welding structural parts.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S890QL steel are higher than that of annealed S890QL steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of S890QL steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.

S890QL steel, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the S890QL steel principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
