The latest EN 10025-6 high strength steel price on China market

At the same time of doing well in EN 10025-6 high strength steel production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the EN 10025-6 high strength steel technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of EN 10025-6 high strength steel, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they EN 10025-6 high strength steel work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the EN 10025-6 high strength steel steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the EN 10025-6 high strength steel steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. EN 10025-6 high strength steel, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, EN 10025-6 high strength steel.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
