Duplex 2205 Stainless Steel

Duplex stainless steels are in most cases, harder than ferritic stainless steels. Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels. Alloy 2205 duplex stainless-steel plate should be annealed at 1900°F minimum, followed by speedy cooling, ideally by water quenching.

The UNS designation for SAF 2205 is S31803/S32205 and the EN steel no. is 1.4462. SAF 2205 or Duplex 2205 is commonly used as an alternative to expensive 904L stainless-steel owing to similar properties but cheaper elements. Duplex stainless-steel is available in multiple varieties like bars, billets, pipes, tubes, sheets, plates and even processed to fittings and flanges. They are not quite as easily welded because the austenitic grades however low thermal growth in duplex grades reduces distortion and residual stresses after welding. The really helpful filler materials for 2205 stainless-steel is 2209.

This mixture allows the alloy to be stronger and more durable than normal austenitic steels. Duplex stainless steels like 2205 additionally maintain good weldability of their thickest sections, and they are much extra proof against stress corrosion cracking than normal austenitic steels.

Although machinable, the high strengths of duplex stainless steels makes machining difficult. As an instance, machining of 2205 is around 20% slower than for 304. Duplex 2205 stainless steel is used extensively in applications that require good corrosion resistance and strength. The S31803 grade chrome steel has undergone numerous modifications leading to UNS S32205, and was endorsed in the yr 1996.

• It additionally demonstrates good fatigue strength, in addition to excellent resistance to stress corrosion cracking, crevice, pitting, erosion, and basic corrosion in extreme environments.
• However, the corrosion resistance of the least resistant duplex stainless steels is larger than that for probably the most commonly used grades of stainless steels, i.e. 304 and 316.
• It is the most extensively used duplex stainless-steel grade and is characterized by excessive yield strength, double that of the standard austenitic stainless-steel grades.
• Duplex 2205 is a two-section, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel.

austenitic

Ferritic stainless steels, similar to 430 and CB-30 grades, are more durable, less ductile, and magnetic as a result of their predominately ferrite makeup. Duplex stainless steels are normally chosen for their high mechanical properties and good to very high corrosion resistance . The technical advice and proposals made in this Product Data Sheet shouldn’t be relied or acted upon with out conducting your individual additional investigations, together with corrosion publicity checks the place wanted.
