1.4429 Austenitic stainless steel seamless pipe

Austenitic stainless steel 1.4529 was developed on the basis of the 904l/1.4539 alloy. However, the molybdenum content of 1.4529 is increased to 6.5%. 1.4529 has excellent general corrosion resistance and improved resistance to pitting and crevice corrosion. Resistance to stress corrosion cracking is also increased. It is often called super austenitic stainless steel

product feature
Increased resistance to stress corrosion cracking compared to other austenitic stainless steels

Excellent overall corrosion resistance when using oxidizing and reducing media

Less tendency to form intermetallic phases than similar steels containing only 18% nickel

Very good resistance to pitting and crevice corrosion

Approved for pressure vessels with temperatures between -196 and 400°C

In September 1998, the German Institute of Structural Engineering issued a building permit for stainless steel components and fasteners.

Alloy 6XN (UNS N08367) material was developed in the United States. It has almost the same composition and is used in the same applications. However, this material is not listed on the VdTÜV table and does not have its own material standard. Therefore, use in European pressure applications is difficult.

Almost the same material was used as 1.4529 in Europe and UNS N08367 in the United States. Therefore, at Shanghai Yuangang, we stock dual-certified materials for international use.
