What are the common defects of A588 Gr A tensile strength welding

In production and operation, the company always attaches great importance to product A588 Gr A tensile strength quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market A588 Gr A tensile strength. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

The company specializes in steel plate cutting, steel plate processing and wide thick plate, hot rolling coil. The company possesses advanced CNC steel plate cutting processing equipment, first-class technical personnel, supporting marketing and after-sales service system. Steel plate cutting parts are mainly used in mechanical manufacturing, shipbuilding, steel structure and mold processing industries, and we can provide A588 Gr A tensile strength, finished products and semi-finished products processing according to the needs of users.

Heat treatment advantages of A588 Gr A tensile strength, SA516 Gr 70 pressure vessel steel:
1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased.
2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness.
3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition.
4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

A588 Gr A tensile strength, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.

Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, A588 Gr A tensile strength, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s A588 Gr A tensile strength domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

The company's after-sales service team is a high-quality professional team. Most after-sales employees have rich service experience and have reached the level of after-sales engineer. The after-sales department implements the after-sales personnel responsibility system and a 24-hour response mechanism. The company's advanced customer relationship management system provides customers with "standardized and streamlined services". A sound customer relationship maintenance system, and a "one-stop" customer satisfaction tracking system, all reflect our strong after-sales service guarantee.
