Stainless steel seamless steel pipe is a kind of long steel with hollow section and no joints around. Stainless steel seamless pipe
Features of stainless steel seamless pipe:
First, the thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be; Secondly, the process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high sizing cost, and pockmarks and black spots on the inner and outer surfaces are not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.
Duplex stainless steel has about half of ferrite phase and half of austenite phase in its solid solution structure. Generally, the content of small phase should reach 30%. With low C content, Cr content is 18%~28% and Ni content is 3%~10%. Some steels also contain alloy elements such as Mo, Cu, Nb, Ti and N.
Classification of duplex stainless steel:
1. Low alloy type
It indicates the grade (23Cr-4Ni-0.1N). There is no molybdenum in the steel. PREN (pitting resistance equivalent) is 24-25. It can replace AISI304 or 316 for stress corrosion.
2. Alloy
Representative grade (22Cr-5Ni-3Mo-0.15N), PREN (pitting resistance equivalent) is AISI 316L and the corrosion resistance between 6% Mo N austenitic stainless steel is 32-33.
3. High alloy type
It generally contains 25% Cr, molybdenum and nitrogen, copper and tungsten. Standard grade (25Cr-6Ni-3Mo-2Cu-0.2N), PREN (pitting equivalent) is 38-39, and the corrosion resistance of this steel is higher than that of duplex stainless steel with 22% Cr.
4. Super duplex stainless steel
The standard grade (25Cr-7Ni-3.7Mo-0.3N) and PREN (pitting resistance equivalent) are greater than 40, which are suitable for demanding medium conditions and have good corrosion resistance and mechanical properties, comparable to super austenitic stainless steel.
