Product Description

Product Details

Grade 2205 UNS S31803 duplex stainless steel alloy bar peeled finish ASTM A276 standard

Duplex 2205 duplex stainless steel alloy is 22% chromium, 2.5% molybdenum, and 4.5% of nickel, nitrogen alloyed stainless steel. 2205 is characterised by:
1.high mechanical strength – roughly twice the proof strength of austenitic stainless steels.
2.physical properties that offer design advantages.
3.good weldability.
4.high resistance to stress corrosion cracking in chloride-bearing environments and in environments containing hydrogen sulphide.
5.high resistance to general corrosion, pitting and crevice corrosion.
6.high resistance to erosion corrosion and corrosion fatigue.

Bending:

Cold bending will be extremely difficult due to the high yield strength. Any cold working causing more than 10% deformation should be followed by annealing.

Hot bending should be performed at 950oC - 1000oC followed by annealing.

Product Introductionwidth: 750px; height: 346.875px; margin-left: 0px; margin-top: 0px; Introduction:

2205 is a (two phase) ferritic/austenitic stainless steel with high strength and excellent corrosion resistance, as supplied in the annealed condition with a maximum brinell hardness of 290 (Rc31).Characterised by high yield strength, double that of the standard austenitic stainless steel grades, good fatigue strength plus excellent resistance to stress corrosion cracking, crevice, pitting, erosion and general corrosion in severe environments. Again generally out performing the standard austenitic stainless steel grades. 2205 cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working, with subsequent reduction in ductility.It is used extensively by the Marine, Chemical, Petrochemical, Pulp and Paper, Oil and Gas, Transport and allied processing industries.
Typical uses are: Anchor Guides, Conveyors, Fasteners, Bushings, High Strength Pump Shafts, Propellor Shafts, plus various applications currently using standard austenitic stainless steel grades.

Applications:
Typical applications of grade 2205 Duplex stainless steels include the following:
1).Pressure vessels, high pressure storage tanks, high pressure piping, heat exchangers (chemical processing industry).
2).Oil and gas pipelines, heat exchangers, pipe fittings.
3).Sewage treatment systems.
4).Pulp and paper industry classification, bleaching equipment, and stock-handling system.
5).High strength corrosion environment rotary shaft, press rolls, blades, impeller.
6).Ship or truck cargo box
7).Food processing equipment

Annealing:

Heat to 1020oC - 1100oC. Hold until temperature is uniform throughout the section. *Soak as required.Quench in water to obtain optimum corrosion resistance. *Actual soaking time should be long enough to ensure that the part is heated thoroughly throughout its section to the required temperature, 30 minutes per 25mm of section may be used as a guide.Please consult your heat treater for best results.

Forging:

Heat uniformly to 1150oC. Hold until temperature is uniform throughout the section.Do not forge below 900oC. Finished forgings should be air cooled.Finally forgings will require to be annealed in order to obtain optimum mechanical properties and corrosion resistance.

Machining:

The machinability of 2205 in the annealed as supplied condition is lower than either 304 and 316 due to it's higher yield strength (approximately double).Typically 80% as machinable as the standard 304 and 316 grades, but lower against the improved machinability 304 and 316 grades. N.B. All machining should be carried out as per machine manufacturers recommendations for suitable tool type, feeds and speeds.
