In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of 51crv4 hot rolled alloy steel bar customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld 51crv4 hot rolled alloy steel bar steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for 51crv4 hot rolled alloy steel bar manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
