Galvanized seamless steel pipes are widely used, and can be divided into low and medium pressure galvanized seamless steel pipes, high-pressure galvanized seamless steel pipes, and stainless steel galvanized seamless steel pipes according to different requirements. Steel pipe A514 Gr B quenched and tempered steel can be used for industrial pipes with different pressures such as water vapor, air, oil, and gas.
37SiMn2MoV steel is high-grade quenched and tempered steel. A514 Gr B quenched and tempered steel, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.
Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel A514 Gr B quenched and tempered steel produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
Expect in the A514 Gr B quenched and tempered steel goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen A514 Gr B quenched and tempered steel product development technology, excellent production team, hand strict quality control, sales and after-sales service.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
