Mechanical properties of duplex 2205 stainless steel pipe:
Yield Strength RP0.2 / MPa:≥450
Tensile Strength Rm / MPa:≥655
Elongation after break A/%:≥25
Hardness value:HBW≤293;HRC≤31
◆ Characteristic
Because it contains 22%-23% chromium, 3%-3.5% molybdenum and 0.14%-0.20% nitrogen, the pitting and crevice corrosion resistance of duplex 2205 welded pipe has been greatly improved, and it is resistant to corrosion in most environments. Corrosion is much stronger than 316/316L steel.
2205 duplex stainless steel has good oxidation resistance and weldability at high temperature, and can be welded using welding techniques such as GTAW, GMAW, SMAW, SAW, FCW and PAW.
In terms of heat treatment, duplex 2205 pipe is mainly used for solution annealing and stress relief. During solution annealing, it should be annealed at a temperature of 1020°C-1100°C and cooled rapidly. Stress relief should be performed at temperatures below 1900°F.
◆ Industry&Application
Industry:
2205 stainless steel pipe is widely used in oil and gas industry, marine engineering, chemical industry, pulp and paper industry and other industries.
