China supply carbon steel nm500 steel equivalent price

The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with NM500 steel equivalent high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".

Q420q material is a kind of structural steel plate for bridges, and there are three quality levels Q420qD, Q420qE and Q420qF. When the Q420q plate is required to have the performance in the thickness direction, the symbols Z15, Z25, Z35 representing the performance level in the thickness direction are added after the above-mentioned grades. Namely Q420qDZ15, Q420qDZ25, Q420qDZ35, Q420qEZ15, Q420qEZ25, Q420qEZ35, Q420qFZ15, Q420qFZ25, Q420qFZ35.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. NM500 steel equivalent, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

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 NM500 steel equivalent 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 NM500 steel equivalent steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the NM500 steel equivalent raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
