What is minimum yield strength of S890QL equivalent?

The company adopts the S890QL equivalent international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S890QL equivalent management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

ASTM A387 steel S890QL equivalent specification refers to 6 grades levels of alloy steel plate for elevated temperature applications, classified by chromium and molybdenum content, Grade 11 and Grade 12 has similar chemical content,they can be used in welded S890QL equivalent pressure vessels and industrial boilers, and mostly in oil gas and petrochemical industry, generally it is used for transportion of medium at high temperature.

The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. S890QL equivalent, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.

Oxygen (O) is a harmful element in steel such as S890QL equivalent. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. S890QL equivalent, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
