Manufacturing technology of St52-3 carbon steel plate sheet

Some St52-3 carbon steel plate sheet, low-alloy high-strength steels have good atmospheric corrosion resistance.In some cases, appropriate precautions can be taken, and they can even be used without being coated in the atmosphere. The elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel and molybdenum. The excellent atmospheric corrosion resistance of some low-alloy high-strength steels has led to the formation of new concepts in the design of buildings, bridges and other structures, that is, these structures are constructed with appropriate exposed components of low-alloy high-strength steel.

Due to the rapid development of the epidemic globally, many nations have moved to a position of “social distancing” in an effort to delay the spread of the COVID-19 virus. Cases have now been detected in most countries worldwide and community spread is being detected in a growing number of countries. The World Steel Association (worldsteel) has cancelled or postponed all our upcoming membership committee meetings. In a few cases they may go ahead electronically but the majority will be reconvened at a later date.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with St52-3 carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as St52-3 carbon steel plate sheet, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.
