Q690E carbon steel material,1.0038, which one is better for construction?

Q690E carbon steel material,Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries It is a modern high-tech professional enterprise integrating scientific research, production and sales,Q690E carbon steel material.

The strength of Q690E carbon steel material, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing Arc welding and contact welding have good welding performance and small thickness during gas welding Cracks are likely to occur on parts with strict shape requirements or complex shapes,Q690E carbon steel material.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. Q690E carbon steel material, 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.

Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's requirements.

As for the mechanical properties of ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.Q690E carbon steel material

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.Q690E carbon steel material
