Description :
This product is a high-performance super austenitic stainless steel seamless steel pipe, covering various high-end grades such as 904L, S31254 (254SMO), N08367 (AL-6XN), and S30432. Super austenitic stainless steel significantly enhances its resistance to pitting and crevice corrosion in chloride environments by increasing its molybdenum and nitrogen content, while also possessing excellent resistance to stress corrosion cracking.
This series of products is widely used in harsh industrial environments, such as seawater desalination devices, flue gas desulfurization systems (FGDs), petrochemical heat exchangers, pulp bleaching equipment, and offshore platform pipeline systems. Among them, 904L steel grade has excellent resistance to reducing media such as sulfuric acid and phosphoric acid due to its high content of nickel and molybdenum; S31254 and N08367, with their extremely high PREN values (pitting equivalent), are ideal choices for handling high concentration chloride ion media and are commonly used as alternatives to expensive titanium or nickel based alloys, offering higher cost-effectiveness.
The product is strictly produced in accordance with international mainstream standards such as ASTM A312 and ASTM A790, ensuring stable chemical composition and superior mechanical properties. The surface smoothness of the pipe is high, the dimensional accuracy is good, and it supports seamless cold rolling or hot rolling processes. Solid solution treatment and acid pickling passivation can be carried out according to customer needs to meet the cleanliness and corrosion resistance requirements under different working conditions. Suitable for key fields such as electricity, chemical industry, environmental protection, and pharmaceuticals that require extremely high corrosion resistance of materials, it is a high-quality basic material that ensures long-term operation safety and reduces maintenance costs.
