In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product S355J2WP atmospheric corrosion resistant structural steel structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel S355J2WP atmospheric corrosion resistant structural steel supplier in the world.
BBN STEEL is an agreement direct selling agent of Wuyang Iron and Steel Company, which mainly deals in medium and extra wide and extra thick steel plates. There are more than 8,000 tons of steel S355J2WP atmospheric corrosion resistant structural steel plates of various specifications for customers to choose. The company's steel plate processing plant can cut semi-finished products and special-shaped parts according to user requirements, and can also transport on behalf of office roads, railways and shipping.
Advantages of S355J2WP atmospheric corrosion resistant structural steel, stainless steel: 1. Chemical properties: the chemical and electrochemical corrosion resistance of stainless steel is the best in steel, second only to titanium alloy. 2. Physical properties: stainless steel has good heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance. Stainless steel can work safely at - 270℃ - 400℃ for a long time. No matter at high or low temperature, no harmful substances will be precipitated, and the stainless steel material properties are quite stable.
Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as S355J2WP atmospheric corrosion resistant structural steel, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.
What is the difference between Q345B steel and Q345A steel? S355J2WP atmospheric corrosion resistant structural steel, 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.
