The comprehensive mechanical properties of grade P235GH steel standard, Q345B steel plate are good, the low temperature performance is acceptable, and the plasticity and weldability are good. Q345B steel is used for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads, mechanical parts, building structures, general metal structural parts. Plate Q345B is the most versatile and the most used pressure special steel plate for container.The company has sufficient inventory and complete varieties and specifications. In line with the sales principle of low price operation and quality first, let customers buy grade p235gh steel standard at ease and use it comfortably! Integrity, professionalism and efficiency are our service tenets. We will wholeheartedly provide excellent grade p235gh steel standard products and high-quality services for new and old customers. We also sincerely welcome new and old customers to call and write to discuss business and guide work!Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while grade p235gh steel standard steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of grade p235gh steel standard steelmaking: converter, electric furnace and flat furnace The converter steelmaking process is most widely used,grade p235gh steel standard., Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.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 grade p235gh steel standard principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
