Carbon and low alloy EN steel grade S275J2 material with high strength

EN steel grade S275J2 material, Steel pipes are widely used in our life, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Steel pipe can also be used to manufacture building structure grid, prop and mechanical support, which can reduce weight, save metal by 20-40%, and realize factory mechanized construction. For steel pipes on the market, in fact, there are seamless pipes and welded steel pipes. If not purchasing often, buyers will easily ignore their models and some material problems.

Boilers with different parameters, different capacities, and different structures have different EN steel grade S275J2 material, steel consumption rates. Boilers with small capacity and high steam parameters have high steel consumption. Boilers with low steam parameters mainly use low-carbon steel, while boilers with high parameters use a larger amount of heat-resistant alloy steel, and their cost is much higher. In addition, because the once-through boiler has no steam drum or downcomer, steel consumption has also been reduced.

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 steel grade S275J2 material 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 steel grade S275J2 material 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.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
