A573Gr70 plate technical conditions: the chemical composition and mechanical properties of A573Gr70 steel are produced in line with ASTM A573. When ordering, additional impact, flaw detection, z direction, composition control, performance requirements beyond the standard can be added. Available heat treatment processes of P235GH steel, A573Gr70 plate: hot rolling, controlled rolling, normalizing, tempering, quenching, normalizing + tempering. Our company supply flaw detection Z15-Z35 thickness direction performance.

The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, p235gh steel professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better p235gh steel tomorrow!

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 p235gh 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 p235gh 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.

Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, p235gh steel, and greatly improves the steel material's resistance to atmospheric corrosion.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
