2205 is a duplex stainless steel, with a chemical composition of almost equal proportions of austenite and ferrite. This mixture allows the alloy to be stronger and harder than normal austenitic steels. Duplex stainless steels like 2205 additionally keep good weldability in their thickest sections, and they’re much more proof against stress corrosion cracking than normal austenitic steels. Even in chloride and sulphide environments, duplex stainless steels exhibit very excessive resistance to emphasize corrosion cracking. Duplex stainless steels are extraordinarily corrosion resistant, work hardenable alloys.
Duplex 2205 is a two-part, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to six% nickel alloyed stainless-steel. It is the most broadly used duplex stainless steel grade and is characterised by high yield strength, double that of the standard austenitic stainless-steel grades. It also demonstrates good fatigue power, as well as excellent resistance to stress corrosion cracking, crevice, pitting, erosion, and common corrosion in extreme environments.
The welding of 2205 just isn’t tough, however it is necessary to design welding procedures that result in a favorable part stability after welding and can avoid precipitation of detrimental intermetallic or nonmetallic phases. Alloy 2205 duplex chrome steel plate combines excessive energy and excessive corrosion resistance to provide excessive corrosion fatigue energy. Applications during which processing gear is topic to both an aggresively corrosive enviroment and to cycle loading can benefit from the properties of 2205 duplex chrome steel plate.
Corrosion Resistance
- Duplex 2205 is a two-part, ferritic, austenitic 22% chromium, three% molybdenum, 5 to six% nickel alloyed stainless-steel.
- It additionally demonstrates good fatigue strength, as well as excellent resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in extreme environments.
- It is the most extensively used duplex stainless steel grade and is characterised by excessive yield strength, double that of the usual austenitic chrome steel grades.
Our stainless production range
Alloy 2205 duplex chrome steel plate should be annealed at 1900°F minimum, followed by rapid cooling, ideally by water quenching. This remedy applies to both solution annealing and stress relieving. Stress relief therapies at any lower temperature carry the danger of precipitation of detrimental intermetallic or nonmetallic phases. Alloy 2205 duplex stainless-steel plate is instantly sheared and cold fashioned on gear suited to working stainless steels. However, due to the excessive energy and rapid work hardening of 2205 duplex chrome steel plate, forces considerably larger than these for austenitic steels are required to cold type it.
The UNS designation for SAF 2205 is S31803/S32205 and the EN metal no. is 1.4462. SAF 2205 or Duplex 2205 is commonly used as an alternative choice to costly 904L chrome steel owing to similar properties however cheaper elements. Duplex chrome steel is out there in a number of types like bars, billets, pipes, tubes, sheets, plates and even processed to fittings and flanges. Alloy 2205 duplex stainless-steel plate possesses good weldability. The goal of welding 2205 is that the weld metal and heat-affected zone (HAZ) retain the corrosion resistance, energy, and toughness of the bottom steel.
This leads to a microstructure that gives corrosion properties and toughness roughly equal to that of the mother or father metallic. Testing based on ASTM A262 PRE (Strauss´ test) presents no problems for welded joints in Sandvik SAF 2205™, which cross with out reservations. When scorching forming is required, the workpiece ought to be heated uniformly and worked in the vary of 1750 to 2250°F. Alloy 2205 duplex stainless steel plate is quite delicate at these temperatures and is quickly shaped. Immediately under this vary, the austenite turns into considerably stronger than the ferrite and may cause cracking, a particular hazard to “cold” edges.
This treatment applies for both solution annealing and stress relieving. Combining most of the helpful properties of both ferritic and austenitic steels, 2205 is probably the most broadly used duplex stainless steel grade.
