ASME SA 53 seamless pipe is a low carbon ASTM A514 QT steel plate steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized ASTM A514 QT steel plate steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.
At the same time of doing well in ASTM A514 QT steel plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the ASTM A514 QT steel plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the ASTM A514 QT steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between ASTM A514 QT steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
Corrosion resistance mechanism of ASTM A514 QT steel plate, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
