ATSM A790 Duplex stainless Steel Pipe S32003 Can be used in making
chemical equipment
Product Discription:
022Cr21Ni3MoN (S32003)
Containing 1.5% Mo, combined with Cr and N to improve corrosion
resistance, its corrosion resistance is better than 022Cr17Ni12Mo2
(316L stainless steel), close to 022Cr19Ni13Mo3 (317L stainless
steel), is an ideal substitute for 022Cr17Ni12Mo2 (316L stainless
steel). At the same time, the steel also has a high strength, can be used
in chemical storage tanks, pulp and paper, building roofs, Bridges
and other fields.
Features:
- High cold deformation plasticity
- The welding performance of arc welding and contact welding is good
Duplex stainless steel corrosion resistant. They have strong
resistance to inter-granular corrosion. Even in chloride and
sulfide environments, duplex stainless steels show very high
resistance to stress corrosion cracking. Duplex stainless steel
work hardening alloy. Their micro-structure consists of austenitic
phase and ferritic phase. Therefore, duplex stainless steel shows
the characteristics of austenitic and ferritic stainless steel.
This combination of properties may mean some compromise compared to
pure austenite and pure ferrite.
Use of S32003 duplex stainless steel:
S32003 Duplex steel can be used to make chemical equipment,
mechanical parts for use in corrosion resistant conditions, bolts
and nuts, pressure vessels, etc
