Pressure Vessel Quality sa573 gr.70 hot rolled structural steel coil Plate

ST52-3 low alloy steel is equivalent to domestic brand Q345. St52-3 new material number: 1.0570, old material number: 1.0841. St52-3 takes its tensile strength and yield point as its main characteristics. sa573 gr.70 hot rolled structural steel coil products are generally used in the manufacture of various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment used in mining and various engineering constructions And other structural parts.

The company attaches great importance to systematic management, and has passed the sa573 gr.70 hot rolled structural steel coil ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on sa573 gr.70 hot rolled structural steel coil quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

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 sa573 gr.70 hot rolled structural steel coil 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 sa573 gr.70 hot rolled structural steel coil manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of sa573 gr.70 hot rolled structural steel coil etc. steel material.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
