Duplex stainless steel
2205
alloy is a duplex stainless steel composed of 21% chromium, 2.5%
molybdenum and 4.5% nickel-nitrogen alloy. It has high strength,
good impact toughness and good overall and local resistance to
stress corrosion.
2205 stainless steel bar characteristics:
Compared with ferritic stainless steel and martensitic stainless
steel, duplex stainless steel has higher toughness, lower brittle
transition temperature, better intergranular corrosion resistance
and weldability, while retaining some characteristics of ferritic
stainless steel, such as high thermal conductivity, low linear
expansion coefficient and superplasticity. Its strength is
higher, especially its yield strength is significantly improved,
and its properties of resistance to intergranular corrosion,
stress corrosion and corrosion fatigue are obviously
improved.
2205 duplex stainless steel round bar size and production
process:
Cold-drawn: Ø1 to 12mm
Hot-rolled: Ø12 to 100mm
Forged: Ø100 to 500mm
