S890QL properties elements content

The company has allocated special environmental protection facilities for all S890QL properties pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, S890QL properties steel mill scale, environmental protection dust has reached 100%.

Low alloy steel plate was originally developed for large diameter oil and gas pipeline in 1960s. Pipeline steel materials used in oil and gas projects require higher strength and toughness than low carbon steel, and have good weldability just the same as low carbon steel.Advantages: S890QL properties, Low alloy steel plate has superior performance and light weight.Disadvantages: Low alloy steel plate is killed steel, so the price will be more expensive.

12Cr1MoVR steel plate is suitable for medium and high temperature pressure vessels, and implements GB713-2014 standard. 12Cr1MoVR pressure vessel plate is usually delivered in normalizing + tempering state. According to the special agreement at the time of order, 12Cr1MoVR steel plate can also be delivered in annealing or tempering state, which significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.

We have a large number of S890QL properties steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the S890QL properties required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.

What is the difference between Q345B steel and Q345A steel?
S890QL properties, Q345B steel and Q345A steel have slight difference in chemical composition:
Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15;
Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15.
The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

There is a careful, patient, enthusiastic and thoughtful after-sales team, a professional distribution, ultra-efficient warehouse and logistics center, a marketing team with marketing expertise, an innovative technology center with strong steel technology, an experienced manufacturing center with rigorous professionalism Quality Inspection Center, an operation team with many years of administrative management experience. Such a strong combination of teams makes BEBON a steel giant in Henan Province.
