Product introduction
The common type of duplex stainless steel material in Chanson Metals’ products line include 329,2205,2507,2304.
329 is a duplex stainless steel with optimized S and Mo to improve mechanical properties. 329 has high mechanical strength and very good resistance to pitting and stress corrosion cracking.
2205 duplex stainless steel pipe has excellent mechanical properties and corrosion resistance, as well as good weldability, it has a wide range of applications in the petroleum and natural gas industry, marine engineering, chemical industry and other industries.
SAF 2507 has the Typical properties:
excellent resistance to stress corrosion cracking in chloride-bearing environments
excellent resistance to pitting corrosion and crevice corrosion
high resistance to general corrosion
very high mechanical strength
physical properties that offer design advantages
high resistance to erosion corrosion and corrosion fatigue
good weldability
2304 is a lean duplex (austenitic-ferritic) stainless steel characterized by the following properties:
Very good resistance to stress corrosion cracking (SCC)
Good resistance to general corrosion and pitting
High strength - approximately twice the proof strength of austenitic stainless steels
Physical properties that offer design advantages
Ease of fabrication and good toughness
Good weldability
