Can duplex stainless steels such as 22253 be used for pressure-bearing bolts?

Standard number for duplex stainless steel 2205: ASTM A240/A240M--01. Duplex stainless steel 2205 is a composite stainless steel alloy composed of 22% chromium, 2.5% molybdenum, and 4.5% nickel-nitrogen. It possesses high strength, good impact toughness, as well as excellent overall and local resistance to stress corrosion. Duplex Stainless Steel, abbreviated as DSS, refers to stainless steel in which ferrite and austenite each make up approximately 50%; generally, the proportion of the minority phase must be at least 30%. At low carbon levels, the Cr content ranges from 18% to 28%, while the Ni content ranges from 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N. This type of steel possesses the characteristics of both austenitic and ferritic stainless steels. Compared to ferritic steels, it has higher plasticity and toughness, no room-temperature brittleness, and significantly improved resistance to intergranular corrosion as well as weldability. At the same time, it retains the brittleness at 475°C and high thermal conductivity associated with ferritic stainless steels, as well as superplasticity. Compared to austenitic stainless steels, it has higher strength, as well as significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel exhibits excellent pitting resistance and is also a nickel-saving stainless steel. High-hardness 2205 duplex stainless steel bolts can be manufactured.
