From this page, you can learn what is the product of our production and sales of duplex stainless steel pipes, industrial welded pipes, stainless steel flanges, etc.

Continuous casting process, also known as billet casting, is the process of solidifying molten metal into "semi-finished" billets, blooms or slabs, and then rolling them in a finishing mill. From wiki. There are two methods for casting duplex stainless steel: die casting and continuous casting. Before the 1960s, most of the duplex steels were die…

In order to illustrate the Acid corrosion resistance of 2205 stainless steel in strong acid solutions, Figure 1 shows the corrosion data of sulfuric acid solution. Figure 1 The medium conditions range from a weakly reducing environment with low acid concentration to a high-concentration oxidizing environment and a medium-concentration strong reducing hot solution. 2205 and…

2707HD duplex steel is a super duplex stainless steel, and its corresponding UNS grade is S32707 stainless steel. Special super duplex stainless steel is designed to solve the lack of local corrosion resistance and strength of super duplex stainless steel heat-resistant chloride. It came out after 2000. The PRE value of S32707 stainless steel can…

Due to its higher corrosion resistance, duplex stainless steel pipes are widely used in petrochemical industries and other industries with harsh media environments. Although duplex steel has good corrosion resistance, leakage in petrochemical industry often occurs due to the corrosion of duplex pipes or other reasons. leakage in petrochemical industry After a short-term operation of…
