In production and operation, the company always attaches great importance to product A573 grade 70 structural steel plate 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 A573 grade 70 structural steel plate. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.
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. A573 grade 70 structural steel plate 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 A283 C mild steel plate comes from the carbon steel which has a low carbon alloy. The mild steel plate/carbon steel plate is a combination of a low amount of chromium, and molybdenum with low carbon as well. Because of the low carbon alloy, it is more weldable, ductile rather than the carbon steel. The mild steel plate A573 grade 70 structural steel plate is created magnetic and has a high amount of ferrite and iron. Mild steel has various characteristics like affordability, easy to weld, machinability.
X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This A573 grade 70 structural steel plate method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. A573 grade 70 structural steel plate, 20CrMo steel pipe is generally used in quenching and tempering state.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel A573 grade 70 structural steel plate products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
