Principal Design Features		This alloy is a duplex stainless steel whose structure is a balance of ferritic and austenitic. It was designed to feature high strength and toughness, resistance to stress corrosion cracking, low thermal expansion, high thermal conductivity and easy fabrication. This alloy is not designed for applications which expose it to temperatures over 570 F for long periods.

Applications		Heat exchangers, feedwater tubes, piping and instrumentation tubing for general service. Industries utilizing this alloy include the coal handling, food and beverage, potash, waste water and pulp and paper.

Machinability		Low speeds and constant feeds will minimize this alloy's tendency to work harden. Tougher than 304 and 316 stainless with a long stringy chip, the use of chip breakers is recommended.

Forming		Due its inherently higher yield strength, initial forming pressures must be higher than those required for standard 300 series stainless steel. Low ductility will make forming operations difficult.

Welding		All common methods including GTAW, SAW and GMAW can be successfully employed. Preheating and post weld annealing is not required. Filler metal should be a balanced ferrite/ austenite type like 2205 or 2304.

Hot Working		This is the recommended method of forming. It may commence after heating to 1750-2000 F, followed by rapid cooling after working. For maximum properties material should be fully annealed after working.

Annealing		Heat to 1710-1920 F(930-1050 c), rapid quench.

Hardening		This material is not hardenable by heat treatment.
