Effect of humidity and temperature on corrosion of SA514 Gr E steel material

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel SA514 Gr E steel material products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the SA514 Gr E steel material market and has strong competitiveness.

40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ～ 60mm when water quenching, and Ф15 ～ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ～ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.

The advantages of SA514 Gr E steel material, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

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 SA514 Gr E steel material 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
